John Guest Female Thread Adaptor - 25mm X 3/4"

This adaptor is specifically designed to connect to 25mm MDPE (Medium Density Polyethylene) pipe.

The threaded end of this adaptor is a 3/4 inch female thread, designed to connect to a 3/4 inch male threaded fitting.

No, this adaptor is exclusively for 25mm MDPE pipe and threaded fittings. It is not compatible with copper or other pipe materials.

For the push-fit connection, ensure the MDPE pipe is clean, cut square, and pushed fully in. For the threaded connection, use PTFE tape or a suitable sealant on the male threads and tighten securely.

This adaptor is designed for standard cold water applications. It is not recommended for high-temperature hot water systems.

The product is supplied in a bag containing 20 units of the female thread adaptor.

Its primary benefit is providing a reliable, durable, and leak-free transition between 25mm MDPE pipe and standard 3/4 inch male threaded fittings.

Ensure the MDPE pipe is cut square, clean, and fully inserted into the push-fit connector. Re-seat the pipe or check for damage to the pipe end or the connector's internal O-ring.

Verify that the 3/4 inch male thread is clean and that PTFE tape or appropriate sealant has been used correctly. Tighten the connection appropriately; do not overtighten.

Check that you are using the correct 25mm MDPE pipe. Ensure the pipe end is not deformed and is free from dirt or obstructions. A slight chamfer on the pipe edge can sometimes help.
