The Air Venturi Ez Fill Valve is equipped with an ASTM COMPLIANT bottle Burst
Disc required by the Department Of Transportation. (D.O.T.). Do not alter this burst
disc in anyway. Make sure the burst disc in the valve is the proper burst disc for the
tank you are using. 5000 psi (5k) for a 3000 psi aluminum tank and 7500 psi (7.5k)
for the carbon ber 4500 psi tanks.
Air Venturi Ez Fill Valve has a Safety Vent Groove on the stem (As shown in below
image). This lifesaving features allow for the venting of the bottle, in the event that
the valve is unscrewed from the bottle with pressure present in the bottle.
ALWAYS CHECK TO MAKE SURE THERE IS NO GAP BETWEEN THE BOTTLE
AND VALVE SEAL (SEE ILLUSTRATION BELOW). IF THERE IS A GAP, STOP!!!
DO NOT FILL OR USE YOUR SYSTEM.
Place the system on the ground and wait for the system to FULLY DE-GAS!
Contact a qualied airsmith IMMEDIATELY! Or Call Air Venturi (216-292- 2570) for

No Gap

The Air Venturi Ez Fill System is equipped
with the industry standard “QD Style” ll tting.
The Air Venturi Ez Fill System may be lled with
Clean, Dry Compressed Air or Nitrogen. Only ll
through the male ll nipple - not through the hose.
When lling your Air Venturi Ez Fill System do not exceed the pressure rating shown on
Air Venturi Ez Fill System or the CYLINDER’S LABEL.
Follow all CGA, DOT and ASTM guidelines and standards in regard to lling and
inspecting the tank prior to lling.
It is important to keep dirt, oil and water out of your Air Venturi Ez Fill System. Most
failures are due to dirt or contamination. Always keep a cover on the ll nipple when
you are not lling the Air Venturi Ez Fill System. If you use compressed air, make sure
that the compressor providing that air is equipped with WORKING lters and moisture
separators.
Always make sure the control knob is turned all the way counter clockwise and in the all
the way up "off" position.
Only the lower tank gauge will read pressure, the output gauge will only read pressure
when in use and dispensing air to the rie.

Micro Bore Hose & Attachment
© Air Venturi 2018 / www.airventuri.com / 216-292-2570
Never operate the Ez Fill System unless a PCP AIRGUN is attached to the ll
adapter on the end of the micro bore hose. Operating the Ez Fill System without a
PCP AIRGUN attached may cause the ll hose to “whip”. Injury may result!!
Do not bend the micro bore ll hose at the crimp ends. Although the hose is rated to 6500
psi bending the hose where the crimp tting is attached to the hose will cause the hose to
break and leak at that location.
Your micro bore ll hose is supplied with a safety qd. This qd is a stainless steel 5000 psi
rated quick disconnect and has a safety strut installed. This strut allows the unit to leak
and help lessen hose Whip should a male ll nipple not be fully installed. Always hold the
hose at the end when in use just in case.
Ensure the air rie you are lling has a 1/8" male Industrial Interchange quick disconnects,
see gure 1.4a. Pull the sleeve/collar back on the quick disconnect and connect the
female quick disconnect socket to the ll nipple on your PCP air gun.
THE SLEEVE /COLLAR MUST SNAP FORWARD AND BE SECURE! Do not force it on
and if it does not t properly do not ll. See gure below.
If the collar is hard to move once lling is complete do not force it as pressure may be
present. Make sure the hose is fully drained and never remove the qd under any pressure!
DO NOT DISCONNECT THE HOSE UNDER
PRESSURE. DISCONNECTING THE HOSE UNDER
PRESSURE COULD CAUSE DAMAGE TO THE HOSE FITTING AND PERSONAL
INJURY TO THE OPERATOR.

Using e Ez Fill System
The Ez FILL SYSTEM is not a regulator.
Do not over ll your airgun.
The output gauge will only read pressure
when the unit is attached and pressurized.
The gauge will not show the pressure in the
airgun unless you stop lling and maintain air
pressure in the hose.
Attach the female QD (Quick Disconnect) to the
male ll nipple on the rie, SEE page 5.
Slowly turn the control knob clockwise/down
(FIG 1) until air starts to ow into the airgun.
Once air starts owing turn the unit slightly back
or counterclockwise (FIG 2) to stop the air from
owing but do not turn the knob too far as to vent
the air. You what to start the ow of air into the
airgun and then stop the ow of air but maintain
the pressure in the hose. This will allow you to
control the next release of air easily.
Turn the control knob clockwise and watching
the gauge on the airgun ll the airgun to the
proper pressure. Once the proper pressure is
reached stop lling by turning the control knob
counterclockwise all the way up and the unit will
vent the air in the hose allowing you to remove
the female quick disconnect from the airgun.
If more pressure is needed repeat the steps to
desired pressure is reached.

SAFE DIRECTION PRIOR TO DEGASSING THE SYSTEM!!!
IF THE UNIT LEAKS WHENEVER TANK HAS AIR
Check all ttings on the system by spraying the ttings with window cleaner or dunking the
unit in water, the bubbles will show any leaks with the ll valve, gauge, burst disc or neck
connection with the tank. If there are no bubbles on those items or the unit leaks from the
end of the hose the issue is with the valve seat.
IF YOUR LEAK IS AT THE;
Fill nipple threads - Empty the system and remove the ll nipple. Clean both the male
threads and the female threads and inspect threads for damage. Ensure the threads are
fully formed and not damaged. Re apply sealing tape on the male ll nipple threads. See
instructions below on installation.
Fill nipple end - If the ll nipple is leaking from the end of the ll nipple a new o-ring
on the ll nipple is needed or a new ll nipple is needed. Follow the instructions below for
removal and install. Only replace the o-ring with a 006-90 cast urethane and use no lube on
theo-ring. Ensure the entire assembly is clean.
ONLY REPLACE WITH GENUINE AIR VENTURI FILL CHECK VALVE.
The Fill check valve assembly on your Air Venturi valve is one of the items that will require
periodic replacement, either due to leakage or mechanical damage to the OD portion,
follow the procedure below:
1. ALWAYS WEAR SAFETY GLASSES AND POINT THE FILL CHECK AWAY FROM YOUR
SELF AND ALL BYSTANDERS.
2. MAKE SURE THE SYSTEM IS COMPLETELY DE-PRESSURIZED.
3. Use a 7/16" wrench, box end, remove the old Fill check assembly.
4. Clean any debris and old sealant out of the port.
5. Inspect the female 1/8"; NPT ll check port threads on the gas distribution body for any
damage. IF THREADS ARE DAMAGED OR WORN STOP! DO NOT USE THE VALVE SEE AN
AIRSMITH OR CALL 216-292-2570. It is recommended that a go/no-go thread gauge be used
to verify these threads AVAILABLE AT WWW.MSCDIRECT.COM
6. A thread sealant has been applied to the threads on the new Air Venturi Fill
check. Do not use any additional sealant or PTFE tape.
7. Make sure the strut is inserted into the Air Venturi Fill check as show below, and
screw the new assembly into your valve. Turn it in until it is hand tight,
and then tighten a further 1 & ½ turns. It should not be necessary to exceed 100 inch-
pounds of torque to achieve sealing. If a leak still occurs STOP and contact an Airsmith or call

OIL TO ENTER THE BOTTLE OIL DROPLETS WILL IGNITE DURING THE FILL
PROCESS WHICH MAY LEAD TO INJURY OR DEATH.
NOTE: You will notice that the strut in our Air Venturi Fill check Valve has a groove across the “O” Ring end.
This groove is essential for proper gas ow. Always replace the complete assembly. Only replace with Air
Venturi FILL CHECK ASSEMBLY.
Gauge thread leaks - Empty the system and remove the gauge. Clean both the male
threads and the female threads and inspect threads for damage. Ensure the threads
are fully formed and not damaged. Re apply sealing tape on the male gauge threads.
Installing is the same as the male ll valve instructions above and use a 7/16 wrench
on the hex to tighten. Do not force or overtighten as the gauge can be damaged.
Burst disc leaks- See instructions below
- TOOLS REQUIRED: 3/8" BOX WRENCH
- FOR SAFETY AND RELIABILITY ONLY USE Air Venturi REPLACEMENT

TO REPLACE A UNIFIED BURST DISC ASSEMBLY:
1. Unscrew (turn counterclockwise) the failed unit, and discard it. They are not
serviceable.
2. Visually inspect the female port on for damage or debris and blow out if necessary.
If the port is damaged, do not replace the disc. Consult an airsmith or call:
216-292-2570 for assistance. We recommend the female port be checked with a
3/8-24-UNF-2B go/ no go gauge available at www.airventuri.com
3. Screw in the new replacement unit and torque to a minimum 55 inch-pounds and
maximum 95 inch-pounds. UNIFIED BURST DISC MUST BE ASSEMBLED WITH AN
INCH POUND TORQUE WRENCH!
4. If the Burst Disc Assembly does not seal at 95 inch-pounds, the valve should be
inspected by an airsmith or call 216-292-2570 for assistance.
Neck leaks - Remove the unit from the bottle and change the o-ring. The proper o-ring
should be used.
Leaks from the end of the hose - If the unit leaks from the end of the hose the valve
seat needs to be removed and replaced.
No need to remove the valve from the tank, just make sure the tank is completely empty.
Hold the ll valve with a 7/16” deep socket and short extension. The using a wrench on
the ats of the ange turn the body off of the ange, counter clockwise like a normal bolt.
Be careful as the ball and spring will fall out of the ange/body pocket.
The ball and spring may fall out but if not remove the spring from the ange. Make sure
you clean the ball and spring and inside the ange.
Exam the spring and ball and if corroded due to contamination replace with new units
from the included rebuild kit.
Remove the upper assembly from the unit – see instructions for LEAKS WHEN
ACTIVATED, UPPER ASSEMBLY.
After removing all upper assembly components use a long 5/64” allen wrench and insert
the allen wrench into the hole in the body from the top. The allen wrench will contact the
seat and allow you to push the seat out through the stem. A .081 to .085 rod may also
be used to remove the seat.

Leaks from the end of the hose - (cont.)
Once removed, clean the seat and o-ring and check for damage. The other side may be
used but a new seat and o-ring is recommended.
Clean the inside of the body where the seat goes with compressed air and a cotton swab
paying close attention to clean where the seat and o-ring are located in the stem. Make
sure the entire body and ange internal area is completely clean and blowing it out with air
once swabbed is recommended.
To reassemble make sure the seat o-ring is lubed with silicone lube – use no oil.
Using a larger allen wrench or a blunt object push the seat into the body. Make sure the
seat is at and is fully seated into the body. When pushing on the seat you should feel a
slight resistance and then the seat popping into the correct location. If you look through
the stem you should see light through the center hole.
Holding the ange up and down, insert the spring into the ange pocket and then place
the ball on top of the spring. Then screw the body on top of the ange assembly.
Turn the valve over and follow the reassembly instructions for the upper assembly.

If the unit leaks only when relling
Check the output gauge threads and output hose threads on the system by spraying the
ttings with window cleaner or dunking the unit in water while the unit is pressurized and
lling an airgun. The bubbles will show any leaks with the threads of the output gauge
or with either end of the micro bore hose. If there are no bubbles on those items or the
unit leaks from the female quick disconnect or the top of the unit see below for the proper
procedure.

ONLY WORK ON A COMPLETELY EMPTY
AIR SYSTEM!
!WARNING:
ALWAYS WEAR EYE PROTECTION, GLOVES AND
POINT THE AIR SYSTEM IN A SAFE DIRECTION
PRIOR TO DEGASSING THE SYSTEM!!!
!WARNING:

Thread leaks – if the unit leaks from any of the output thread connections follow the
instructions above for removal and reinstall of the output gauge or micro bore hose.
Female Quick Disconnect- If the unit leaks at the female qd while attached to the
male it is the o-ring inside the female qd. The o-ring is a 010 in size and is located
behind the ball bearings in the female quick disconnect. Remove the old o-ring with a
pick and then squeeze the new o-ring into the grove. Starting with one end of the o-ring
in the groove and then using a blunt object to push the other side in will usually get it in
place.
Leaks out the top – If the unit leaks out the top while lling, the 004 o-ring located
inside the unit needs to be replaced with a new o-ring.
Remove the set screw that holds the top of the unit in place – 5/64 inch allen wrench
Unscrew the top of the unit – actuator plug assembly – from the body. A wrench may
be needed to get the assembly started unscrewing but take care not to damage the
body or the assembly.
Unscrew the housing nut by using a 3/4” thin wall socket. Counter clockwise will
remove the nut and remove fully. No ratchet or tool is needed as the nut is only
installed by hand and will turn and remove easily.
Remove the actuator shaft and return spring from the unit. Clean and inspect the shaft,
replacing the shaft is usually not needed unless the shaft is bent.
Using a 3/16 allen wrench remove the o-ring jam nut
The 004 o-ring is located in the pocket and a pick will remove the o-ring but take care
not to damage or scratch the internals during removal.
Make sure the unit is clean
Reassembly is the reverse, install the 004 and push the o-ring into place with a blunt
object.
Screw the o-ring jam nut into place – snug and do not over tighten or torque it in.
Place the return spring in the unit and lube the bottom 1/3rd of the shaft, then insert the
shaft into the unit.
Install the retaining nut into place.You may need to push down on the nut with an allen
wrench through the drive hole of the socket to get the nut to start catching the threads.
Do not overtighten.
Install the top unit in place and install the set screw.

Unit continues to vent once knob is all the way up - if you use the Ez Fill System and
have lled your airgun and have turned the knob all the way up and the unit continues to
vent out the top it is the valve seat or the male ll nipple on the airgun. Let the unit vent
until it stops and verify if the bottle is empty or the airgun.
If the bottle is empty follow the procedure to replace the valve seat inside the stem.
If the airgun is empty a new ll valve will be needed on the airgun and follow the airgun
instructions for ll valve replacement.
Unit does not vent and air is in the hose and showing on output gauge - If you ll
the airgun and turn the knob all the way up to vent but no venting occurs and there is air
showing on the output gauge and you are unable to remove the female quick disconnect
due to pressure. If this is the case you need to drain the system by loosening the burst disc
with a 3/8 box end wrench. Just loosen the burst disc until the system starts to leak and
leave it to vent until it stops. Once it has stopped venting, activate the knob and allow the
air trapped in the hose to vent out of the burst disc and then tighten the burst disc following
the instructions above.
Once the unit is drained, remove the hose from the airgun and remove the upper half
assembly following the directions above. Make sure the spring is in good condition, the
shaft is straight and not bent and the o-ring jam nut is not too tight. If the o-ring jam nut is
too tight this will case the o-ring not to release from the shaft and not allow the unit to vent
properly. Change the 004 o-ring with a new o-ring.
Reassemble the unit with the instructions above.
