HydroSure WRAS Approved Straight Compression Coupling - 32mm - Blue

WRAS Approval means the product has been rigorously tested and meets the Water Regulations Advisory Scheme's strict standards for water quality, safety, and performance in the UK.

No, this fitting is specifically designed for 32mm (external diameter) MDPE or HDPE pipes only. Using it with other sizes will result in leaks or an insecure connection.

There is usually a depth mark on the pipe or fitting. The pipe should be inserted squarely until it reaches this marked depth, ensuring it is fully seated against the internal stop.

The coupling is designed to safely handle working pressures up to 16 bar.

While designed for underground installation, its robust construction may allow for above-ground use in certain applications. However, prolonged UV exposure could degrade the materials over time. Always follow local regulations for above-ground plumbing.

The O-ring is made from durable, anti-perishable materials designed for long-term sealing in underground conditions. Its lifespan is expected to be many years under normal operating pressures and conditions.

Basic tools such as a pipe cutter, deburring tool, and a suitable wrench for tightening the compression nut are generally sufficient. Ensure tools do not damage the pipe or fitting.

Ensure the pipe is fully inserted to the correct depth and the compression nut is adequately tightened. Check the pipe end for damage or ovality. If the issue persists, remove the pipe, inspect for debris on the O-ring and pipe end, and reassemble.

Verify that you are using the correct 32mm pipe size and that the pipe end is clean, round, and free from burrs. Slightly wetting the O-ring or pipe end can sometimes ease insertion, but avoid excessive lubrication.

Confirm the fitting is WRAS approved and compatible with the pipe material. Ensure the O-ring is correctly seated and undamaged. Re-tighten the compression nut carefully, ensuring the pipe is fully seated.
