GENERAL INFORMATION
DESCRIPTION
The SnakeBite XQ Nozzle and Silencer
represents a step change in abrasive blasting
nozzle design and functionality. The unique
internal nozzle geometry of the SnakeBite XQ
Nozzle produces a more stable blast stream
than conventional nozzles. This results
in less blast stream turbulence, improved
stability, higher abrasive particle velocity for
an increased distance after the nozzle exit and
delivers increased abrasive particle energy at
the work surface.
The Silencer has been specically designed
to respond to the characteristics of the blast
stream produced by the SnakeBite XQ Nozzle
and is tuned to remove the typical high pitch
screech of the blast stream and reduce the
sound emitted by the blasting process.
The Silencer design incorporates a nozzle
thrust reduction feature that reduces the
force produced by the nozzle in the opposite
direction to the blast stream.
FEATURES
• Groundbreaking Nozzle internal geometry
that delivers up to 25% increase in surface
cleaning rates and operator productivity
without increased abrasive usage rates.
• Industry leading nozzle silencer delivering
up to 16dB noise reduction across a wide
range of operating pressures.
• Nozzle thrust reduction of up to 40%,
when operated with the silencer tted,
results in a signicant reduction in
operator fatigue over the shift.
• Silicon Nitride ceramic liner offering
excellent wear characteristics and life.
• Robust anodised aluminium nozzle jacket,
including a nozzle exit bump guard,

INSTALLATION
Installing the Nozzle
1. The SnakeBite XQ Nozzle is available in a
range of standard nozzle sizes and includes
a standard contractor inlet thread.
2. Inspect the condition of the nozzle liner and
jacket prior to installing it into the nozzle
holder. Make sure the nozzle liner is not
damaged or cracked or has pieces missing.
Check the nozzle is not excessively worn
by using a nozzle wear gauge – the nozzle
is excessively worn if the throat diameter
has worn to the diameter of the next larger
size nozzle. Inspect the nozzle jacket for
damage. If the nozzle liner is damaged or
excessively worn do not continue to use the
nozzle.
3. Ensure the system pressure is isolated
before installing the nozzle into the nozzle
holder.
4. Clean the threads on the nozzle and the
nozzle holder and make sure they are free
of any grit or debris.
protects the nozzle and liner from the
harsh blasting environment and improved
operator safety.
• Slimline ergonomic nozzle jacket design
providing improved grip and reduced
operator hand fatigue.
• Standard contractor nozzle inlet thread.
Installation - Always isolate the system
pressure prior to installing and removing
the nozzle or silencer and conducting
maintenance. If the Nozzle or Silencer is
damaged, cease using the damaged product.

INSTALLATION
5. The nozzle is installed onto the blast hose
by screwing the bell shaped inlet end of the
of the nozzle into the nozzle holder. Make
sure the nozzle washer is located as shown
below.
6. Continue to screw the nozzle into the nozzle
holder until the nozzle reaches the end of
the nozzle holder thread, then tighten the
nozzle until it is hand tight. Do not over-
tighten the nozzle in the nozzle holder or
use any tools to tighten the nozzle.
7. If the nozzle is to be used without the
silencer, the bump guard must be installed
and securely tted to the outlet end of the
nozzle. Hand tighten the bump guard in the
same way the nozzle is hand tightened.
Note: The bump guard thread is different to
the nozzle inlet thread to ensure the nozzle
cannot be installed backwards.
8. When the nozzle is installed into the nozzle
holder as per the instructions above,
check to make sure the connection is tight
and there is no movement between the
nozzle holder and the nozzle. Check that
the nozzle holder is rmly secured to the
blast hose.
9. The nozzle is removed in the reverse order
to the above sequence.
Note: Ensure the system pressure is
isolated prior to removing the nozzle.

INSTALLATION
Installing the Silencer
1. Inspect the condition of the silencer liner
and jacket prior to installing it onto the
nozzle. Make sure the silencer liner is
not damaged or cracked or has pieces
missing. Inspect the silencer liner wall
thickness at the exit of the silencer –
typically the silencing effect will reduce
if the silencer is excessively worn. The
silencer is excessively worn if the exit
diameter has worn per the following table:
Inspect the silencer jacket for damage.
If the silencer is damaged or excessively
worn do not continue to use the silencer.
2. Ensure the system pressure is isolated
before installing the silencer onto the
nozzle.
3. The nozzle has been designed to be used
with or without the silencer. If required,
remove the bump guard, and clean the
threads on the nozzle exit and the silencer
and make sure they are free of any grit or
debris.
4. The silencer is installed onto the nozzle by
screwing it onto the outlet end of the nozzle
as shown below.
Note: there is no silencer washer.
5. Continue to screw the silencer onto the
nozzle until the nozzle reaches the end of
the silencer thread, then tighten the nozzle
until it is hand tight. Do not over-tighten the
nozzle in the nozzle holder or use any tools
to tighten the nozzle.

OPERATION
Operators must read and understand fully
this operating manual prior to using the
SnakeBite XQ Nozzle and Silencer.
Operator Competence: Operators must
be trained and competent to undertake
abrasive blasting prior to using the
SnakeBite XQ Nozzle and Silencer.
Blasting operations generate noise levels
that can permanently damage hearing:
operators and nearby personnel are to
ensure appropriate personal protective
equipment, including hearing protection is
worn during blasting operations.
Nozzle and Silencer Care: Take care to
place down the SnakeBite XQ nozzle and
silencer rather than dropping from height
and to avoid impact with hard surfaces as
this may damage the nozzle and silencer.
Operators are required to inspect the nozzle
and silencer for damage or excessive wear
before installing onto the blast hose and
before use.
Nozzle control: The Blasting Process
generates thrust through the nozzle in
the opposite direction to the blast stream.
Operators must maintain a secure grip of
the nozzle on start-up and during blasting
to ensure the control of the nozzle is
maintained and the operator hand doesn't
slip off the front of the nozzle.

shut off Deadman system when using the
SnakeBite XQ Nozzle and Silencer.
WARNING

12
OPERATION
The SnakeBite XQ Nozzle and Silencer are
designed to operate effectively across a
wide range of operating pressures, typically
between 80-110psi, with the optimal and
recommended operating pressure being
100psi. Operating the nozzle and silencer
at pressures other than the recommended
pressure will reduce cleaning efciency and
silencing effect.
It is recommended the blast system used is a
BlastOne Schmidt Pressure hold system tted
with a 2” bull hose coupled to an adequately
sized compressor for the nozzle size used – see
BlastOne catalogue for compressor sizing.
The SnakeBite XQ has been designed to optimise
abrasive blasting using GMA Australian Garnet.
Use with alternative abrasive types may result
in reduced performance outcomes compared to
using GMA Australian Garnet.
Preparing to use the nozzle and silencer
1. Setup Blast system in accordance with
manufacturers instructions and connect
nozzle and silencer as per instruction
above.
2. Clear the work area of any debris and
trip hazards and observe all safety
requirements.
3. Pressurise the system and set the nozzle
outlet pressure to 100psi.
Operator standoff
1. The improved blast stream stability
generated by the SnakeBite XQ Nozzle will
allow an increased standoff distance and
faster cleaning rates - around 500-600mm
(20-24 in) for typical situations.

13
OPERATION
Maintenance: Any maintenance on the
Nozzle and Silencer must only be conducted
by trained and qualied personnel.
