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

WRAS approval signifies that the fitting has been tested and certified to meet the Water Regulations Advisory Scheme's standards for materials and construction, ensuring it is safe for use with potable water in the UK.

While functionally it may work, it is specifically designed for underground installation. For above-ground use, consider fittings designed for UV resistance and aesthetic visibility.

The fitting is designed to withstand working pressures up to 16 bar.

It is designed to connect to 25mm (external diameter) MDPE (Medium Density Polyethylene) or HDPE (High-Density Polyethylene) pipe.

Ensure the pipe is cut cleanly and squarely, fully inserted into the fitting, and the compression nut is tightened securely. The anti-perishable o-ring creates the primary seal.

No, this fitting is specifically designed for 25mm pipe on one end and a 3/4" male thread on the other. Using it with incorrect pipe sizes will result in leaks or connection failure.

The blue colour is typically used to identify pipes intended for non-potable water supply or specific system types, though WRAS approval ensures it meets standards regardless of colour.

Ensure the pipe is cut squarely and inserted fully into the fitting. Check that the compression nut is tightened sufficiently. Inspect the pipe for damage and the o-ring for debris or defects.

Ensure the pipe end is clean and not deformed. Slightly twisting the pipe as you insert it can help. Do not force the pipe; ensure it is seated correctly.

Ensure the 3/4" male thread is clean and the connection is properly sealed, potentially using appropriate thread seal tape if required by the connected component's design.

Confirm the fitting is rated for the operating pressure. Check that the correct pipe size and type (MDPE/HDPE) are being used and that the o-ring is correctly seated and undamaged.
