Pipe Cutting
The stops are located in the following distances from the fitting end.
Twistloc® fittings should be in the "unlocked" position, this shown by coloured line which a small gap between the screw cap and the body. Ensure that they are kept free from scratches, gouges, dirt and debris or any form of damage on the circumference of all fittings.

Tensile Strength Test Maximum Torgues Figures

The maximum torque values for threads used on Twistloc® products are as follows:

The graph above shows the results of a tensile strength test conducted
independently by an independent Laboratory and shows conclusive
proof that Twistloc fittings outperform our competitors.

To Lock The Pipe Connection
Lock Pipe Connection
Ensure that the tubing 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.
Twist Screw Cap Twist the screw cap until coloured line is no longer visible. This confirms a proper, secure fit. This locks the pipe into position and increases pressure on the 'O' ring seal around the pipe for greater security.

Ensure no scratches, gouges or any form of damage on the circumference of the tubing within one [1] inch [24.4mm] of the cut end. Damage in this area may cause leakage problem.

Check Twistloc® fittings for any signs of damage or foreign objects.

When Twistloc® fittings have to be disassembled and then reused, ensure that the tubing that was removed from the joint has no damage on the circumference within 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.

Twistloc® fittings can then be reassembled.

Ensure Twistloc® fittings and pipes are kept clean at all times by keeping them in the bags and boxes provided. Do not empty Twistloc Products onto the floor area.

To Seperate The Pipe Connection

Seperate Pipe Check if the pressure inside the system is released.

Unlock fitting by twisting until coloured line is visible and clicking sound is heard.

Press collets squarely against the face of the fitting. With collets depressed, pull tubing to remove from fitting. Fitting may be reused.


Stop End

If necessary, the Twistloc® Stop End not only provides the permanent leak-prevention sealing effects 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.

Stop End

To assemble fully push in the pipe and pull on pipe to ensure security.
To remove simply push the collet into the body and pull to release the pipe.


Mini Manifold

For maximum flexibility Twistloc® fittings can be combined to provide multiple functions.

Mini Manifold


Do not insert fingers into Twistloc® fittings as the stainless steel teeth may cause injury.

Twistloc® fittings should not be used for gas, fuel, oil or compressed air applications.

DO NOT allow contact with any chemical or foreign substance; paint strippers, solder flux, Acid based descalents or chemical. The additive customer should be consulted.

Twistloc® fittings are not suitable for buried installation.

All Twistloc® fittings and related products should be selected, installed, used and maintained in accordance with these Technical Specifications.

Do not use a damaged or scored pipe.

Cut Pipe
Do not use a hacksaw to cut a pipe. Do not leave burrs on the pipe.

If the pipe is not fully inserted, the connection cannot be properly sealed even if the fitting is coupled.

You must push in the pipe passing the collets [gripper] and the O-ring inside the fitting.
