FAQs

What type of pipe does this coupling fit?

This coupling is designed specifically for 32mm MDPE (Medium Density Polyethylene) pipes.

Can I use this coupling for hot water systems?

No, this coupling is designed and approved for cold water systems only.

What does WRAS approved mean?

WRAS approval signifies that the product has met the strict standards of the Water Regulations Advisory Scheme for use in public water supplies, ensuring it is safe for drinking water.

How many couplings are included in a set?

Each set contains 10 MDPE compression straight couplings.

What are the dimensions of a single coupling?

Each coupling measures approximately 63mm x 63mm x 128mm.

Do I need any special tools for installation?

While a pipe cutter and potentially a wrench for final tightening are recommended, the primary connection is hand-tightened, making installation straightforward.

Troubleshooting

Leak at the connection

Ensure the MDPE pipe is fully inserted into the fitting and the retaining nut is adequately tightened. Check the pipe end for damage or deformation. Verify that the pipe is the correct 32mm MDPE type.

Pipe does not insert fully

Make sure the pipe end is clean, smooth, and cut square. Remove any burrs or obstructions. If the pipe is deformed, trim off the damaged section and try again.

Fitting appears damaged or cracked

Inspect the coupling before installation. If any damage is visible, do not use the fitting and replace it with a new one.
