Pipe stops / Insertion depths are located at the following distances from the fitting end.
fittings should be in the ‘unlocked’ position, this is shown by colored line which a small gap between the screw cap and the body. Ensure that there are kept free from scratches, gouges, dirt and debris or any from of damage on the circumference of all fittings.
When cutting tubing, ensure that the ends are cut square and are free of burrs.
TENSILE STRENGTH TEST
The graph above shows the results of a tensile strength test conducted independently by the Korean Government Laboratory and shows conclusive prove that Twistloc fittings outperform our competitors.
Maximum Torque Figures
The Maximum torque values for threads
used on products are as follows;
To Lock The Pipe Connection
Ensure that the pipe is pushed into the fitting fully past both the collets (gripper) and the ‘O’ ring and is
engaged properly in accordance with the manufacturer’s instructions.
Pull to check it is secure. It is good practice to test
the system prior to leaving the site or before use. If
PEX pipe is used, then a tube insert must be used
also. The tube insert acts as an internal support for
the end of the pipe.
Twist the screw cap until colored ring is no longer visible.
This confirms a proper, secure fit and locks the pipe
into position and at the same time increases pressure
on the ‘O’ ring seal around the pipe for greater
Ensure no scratches, gouges or any form of damage on the circumference of the pipe within one (1) inch
(25.4mm) of the cut end. Damage in this area may cause leakage problem.
Check fittings for any signs of damage or foreign objects.
When fittings have to be disassembled and then reused, ensure that the pipe, removed from the
joint, has no damage on the circumference with one(1) inch (25.4mm) of the end. Inspect the tube and fitting
for any signs of damage and ensure they are free of foreign materials. fittings can then be
Ensure fittings and pipes are kept clean at all times by keeping them in the bags and boxes
provided. Do not empty Products onto the floor area.
To Separate the Pipe Connection
Before attempting to disconnect any fitting, make
sure that the system is de-pressurized.
Unlock fitting by twisting until colored ring is visible.
Press collets squarely against the face of the
With collets depressed, pull on the pipe to
remove it from the fitting.
If necessary, not only provides a permanent leak-prevention sealing effect but also enables
immediate removal and system extension for re-work. In particular, this is a Push-in design for easy use.
The Stop End is also useful in system pressure testing prior to connection works.
Fully push in the pipe and pull to check it is secure. The release, depress the collet and pull out the pipe.
For maximum flexibility fittings can be combined to provide multiple functions.
To maintain the pipe radius.
For sharp bends, standard elbow fittings can be used. For slight bends it is possible to use the flexibility of the pipe to produce a bend which can be clipped into shape, or tighter still with a 15mm cold forming bend, subject to the following limits.
Do not insert fingers into fittings as the stainless steel teeth may cause injury.
If PEX pipe is used, then a tube support liner must be used also. The tube support liner acts as an internal support for the end of the pipe.
fittings should not be used for gas, fuel oil or compressed air applications.
DO NOT allow contact with any checmical or foreign substance; paint stripers, solder flux, Acid based descalents or chemical.
fittings are not suitable for buried installation
All fittings and related products should be selected, installed, used and maintained in accordance with these Technical Specifications.
When cutting pipe, ensure that the ends are cut square and are free of burrs.
Ensure that there are no scratches, gouges or any form of damage on the circumference of the pipe within 1 in. (25.4mm) of the cut end. Damage in this area may cause leakage. Check the fitting for any signs of damage or foreign objects.
Do not use a damaged or scored pipe.
Do not use a hacksaw to cut a pipe. Do not leave burrs on the pipe.
Ensure that the pipe is pushed into the fitting fully and is engaged properly in accordance with instructions.
If the pipe is not fully inserted, the connection cannot be properly sealed even the fitting is coupled.
You must push in the pipe passing the collets (gripper) and the O-ring inside the fitting.
When a connection has to be disassembled and reused, ensure the pipe has no damage around the circumference within 1” (25.4mm) of the end. Inspect the tube and fitting for any signs of damage and ensure they are free of foreign materials. The connection can then be reassembled.
