1.0 General Product & Safety Information
1.1 Product Information
The CRD220SS Tube Expander is designed to expand flexible tubing up to a durometer
of Shore A85 (Shore D35), including any non-metallic braided materials.
The device only works with tubing that has an inside diameter of 7/16” to 3/4”.
The standard jaw sets are universal and are designed to be used with an inside diameter
range of 7/16” to 3/4". Other jaw sets are available that are optimized for a specific size
(see accessories page at www.cleanroomdevices.com or call Clean Room Devices, Inc.).
The device features simple yet reliable tool-less jaw adjustment, which can be made by
the operator.
The device features a calibrate-able pressure gage conveniently mounted for addition
process control.
1.2 Safety Information
The device has a foot pedal actuated air cylinder that actuates the expanding jaws. The
unit is not intended to expand anything other than flexible tubing.
Avoid placing your fingers between the upper jaw block and the air cylinder
mounting bracket while operating unit, sufficient pressure exists to cause personal
injury.
The air supply should be free of moisture/contaminates, and set at 80-130 psi. It is
recommended that a suitable filter/regulator be installed onto the supply line prior to the
unit to preserve the life expectancy of the air regulator and air cylinder.
2.0 Installation
Ensure all five (5) rubber feet are completely stabilized on your work surface prior to
applying air pressure to the unit.
2.1 Air Supply
Connect a 1/4” air supply hose to the inlet on the pressure regulator. The air supply
should be free of moisture and contaminates and provide a minimum of 100 psi.
The regulator on the unit should be set to 80-120 psi.

3.0 Operation
3.1 Tube Expanding
To adjust the jaws for the size tubing to be expanded start by loosening the knurled
Lock Nut.
With the compressed air attached to the expander, actuate the foot pedal which will
activate the expander. Keeping the foot pedal down adjust the expander lower jaw to the
position you want using the Thumb Wheel Knob.
Turning the nut clockwise will increase the jaw expansion size, counter clockwise will
decrease the jaw expansion size. This adjustment may require fine tuning depending on
your tubing I.D., O.D., durometer and/or material.
Once you have the expansion size you want tighten the Lock Nut to secure the
adjustment. Release the foot pedal.
Place the tube over the ends of both expander jaws and hold firmly in place.
Actuate the Tube Expander by pressing the foot pedal.
Once the tube is expanded, release the foot pedal, rotate the tubing 90 degrees on the jaws
and actuate the Tube Expander by pressing the foot pedal again.
Note: Several expanding actions may be necessary to effectively expand the end of
the tube for the fitting/connector to slide in. Each time you expand the tubing
remember to rotate the tubing 90 degrees on the jaws.
Quickly insert the component or tube connector before the tubing regains its original
size.

3.2 Jaw installation and removal
Tools required are 9/16 open wrench, 3/4 open wrench and a 5mm, 3mm and 3/32nd hex
wrench
Remove jaw guard by removing two 5x10mm screws using a 3mm hex wrench.
Turn the thumb wheel clockwise until the cylinder shaft is fully extended in the jaw block
channel. Figure 3.2.1
Cylinder shaft shown fully extended in jaw block channel
Figure 3.2.1
Using a 3/4" open end wrench break the upper jaw nut loose. Figure 3.2.2
Using a 9/16” open end wrench break the lower jaw nut loose. Figure 3.2.3
Figure 3.2.2 Figure 3.2.3

Now remove the two 6x12mm screws holding the front cylinder mount bracket using a
5mm hew wrench. Figure 3.2.4. Rotate the cylinder backwards until it stops in the semi-
vertical position. Figure 3.2.5
Remove two 6x12mm screws Cylinder semi-vertical position
Figure 3.2.4 Figure 3.2.5
Rotate the upper jaw by hand counter clockwise until removed.
Important note: when screwing upper jaw onto cylinder shaft it is important to only
screw the jaw 1/2 to 2/3 of the way on. Any farther and the jaw may slip off the jaw
block when the cylinder is retracted.
Remove the Knurled lock nut and grab threaded rod by hand and rotate rod counter
clockwise while holding the lower expander jaw until the jaw is removed. Figure 3.2.6

Select replacement jaw set and assemble them in the reverse order of operations.
Note: If the cylinder shaft won’t retract when being cycled the adjustment of both
set screws on the front cylinder mount bracket will need to be adjusted. To make the
adjustment you must first loosen the two 6x12mm screws using a 5mm hex wrench
(Figure 3.2.7.) and then by adjusting the two set screws using a 3/32nd hex wrench.
(Figure 3.2.8.) Now tighten the two 6x12mm screws and ensure jaw alignment.

5.0 Troubleshooting
Operating Error
Action
Unit does not operate.
1. Check the facility air.
2. Check all air hose connections on the unit.
Jaws do not expand.
1. Ensure there are no obstructions keeping the
jaws from expanding.
2. Completely depress the foot pedal to actuate.
3. Verify that the tubing is within the
recommended durometer and size range.
Flexible tubing is splitting/tearing.
1. Verify that the tubing is within the
recommended durometer and size range
2. Ensure the lower jaw has been adjusted
correctly for the tubing inside diameter (I.D.).
3. Verify facility air supply psi or unit pressure
adjustment.
6.0 Maintenance
6.1 Periodic Cleaning (annually)
Wipe down outer surfaces with alcohol, septihol or mild detergents as required.
7.0 Safety
The jaws are a PINCH POINT, therefore DO NOT OPERATE the Tube Expander
without the clear safety guard bolted in place.
