What is WIS 4-41-01?

WIS 4-41-01 is a Water Industry Specification outlining the requirements to connect pipes on adopted systems, which the Flexseal SC137 complies with.

What tools are needed for installation?

A nut driver and a torque wrench are required for installation.

What materials are used in the coupling?

The coupling features a stainless steel shear band and other materials designed to withstand various environmental conditions.

What is the pressure rating of the Flexseal SC137?

The coupling can withstand an internal pressure of up to 2.5 bar.

Where can the coupling be used?

How do I ensure a watertight seal?

Ensure the pipe ends are clean, the coupling is properly positioned, and the nuts are tightened to the correct torque specification.

Troubleshooting

Leakage at the joint

Check the torque of the nuts and tighten if necessary. Ensure the coupling is properly centered and the pipe ends are clean.

Difficulty in tightening the nuts

Ensure the nut driver and torque wrench are the correct size and type. Lubricate the threads if necessary. Check for obstructions.

Pipe misalignment after installation

Ensure the pipes are properly aligned before tightening the coupling. Check for any obstructions preventing proper alignment. Ensure the shear band is correctly positioned.
