HydroSure WRAS Approved Adaptor Compression Fitting - 25mm x 3/4" - Blue

WRAS (Water Regulations Advisory Scheme) approval means the product has been tested and meets the high standards set for materials and fittings used in public water supplies in the UK, ensuring it is safe for drinking water.

No, this fitting is specifically designed for 25mm external diameter pipes only. Using it with other sizes will result in a poor or non-existent seal and likely leaks.

It is designed to work with 25mm external diameter MDPE (Medium Density Polyethylene) or HDPE (High Density Polyethylene) WRAS approved pipes.

The fitting is rated for working pressures up to 16 bar.

Ensure the pipe end is cut perfectly square, is free of burrs, and is fully inserted into the fitting before tightening the compression nut securely. The O-ring's design helps create a tighter seal under pressure.

Yes, its robust construction and high-pressure tolerance make it suitable for both above-ground and underground installations, provided the pipework is protected from damage and extreme environmental conditions.

Ensure the pipe is cut squarely and inserted fully into the fitting. Check that the compression nut is tightened sufficiently (but not over-tightened). Verify that the pipe is the correct size (25mm OD) and type (MDPE/HDPE).

Check that the pipe end is clean, free of burrs, and not deformed. Ensure the correct size and type of pipe is being used.

Ensure the threads on both the fitting and the connecting female part are clean and undamaged. Lubricate threads lightly with a suitable water-safe lubricant if necessary.
