The Pipe Cowl is a pre-soldered solution for pressure relief termination. Traditional pressure relief terminations require extra tube, 2 bends and 4 soldered joint to be made resulting in a different finish each time. The pipe cowl has the advantage of guaranteeing a neat finish every time, with one soldered joint to make meaning installers save time and money. The pipe cowl also complies with all current legislation and NHBC approved.

The solder ring pipe cowl is ideal for domestic and commercial applications and is available in two sizes to enable fixes to both 15mm and 22mm copper tube which is manufactured to BS EN 1057. We are also delighted to introduce the new extended pipe cowl, with 400mm of 15mm copper tube. This enables the installer to carry out full installation from inside the building. This removes the need of spending time and money on scaffolding or abseiling allowing for easy high-level installation.
