HydroSure WRAS Approved Elbow Compression Fitting 20mm x 3/4" Male - Pack of 3 - Blue

WRAS (Water Regulations Advisory Scheme) approval means the product has been rigorously tested and meets the high standards set for products that come into contact with drinking water in the UK, ensuring it does not contaminate the water supply.

This fitting is designed to operate safely at working pressures up to 16 bar.

No, this specific fitting is designed exclusively for 20mm external diameter MDPE or HDPE pipes. Using it with a different pipe size will result in a poor seal and likely leaks.

It connects to MDPE (Medium Density Polyethylene) or HDPE (High-Density Polyethylene) pipes with an external diameter of 20mm.

The 3/4" male thread is designed to screw into a corresponding 3/4" female threaded socket, such as on a tap, valve, or other plumbing fitting.

Generally, standard pipe cutters and wrenches are sufficient. No specialized or powered tools are required for typical compression fitting installation.

While designed for underground installation, it can be used above ground provided it is protected from UV degradation and physical damage. Its primary design benefits are most relevant in buried applications.

Ensure the pipe is inserted fully to the internal stop. Check that the compression nut is tightened sufficiently (but not over-tightened, which can damage the pipe). Verify the pipe is the correct size (20mm external diameter) and that the end is cut cleanly and squarely. Inspect the O-ring for damage or debris.

Make sure the pipe end is clean and slightly chamfered if necessary. Ensure the compression nut and ferrule are correctly positioned on the pipe and not obstructing insertion. A small amount of silicone lubricant (approved for potable water) can sometimes aid insertion, but avoid excessive amounts.

The pipe may not have been fully inserted. Dismantle the fitting and re-insert the pipe until it stops. Ensure the compression nut is tightened properly according to instructions. If the pipe is damaged or deformed, it may need to be cut back and a new connection made.
