The Pressure Relief Terminal that will save you time and money

The Pipe Cowl is a pre-soldered solution for pressure relief termination designed to save you time and money. The Pipe Cowl comes in both 15mm and 22mm sizes and also as an extended version to remove the need for any scaffolding when installing in high rise buildings.

Traditional pressure relief terminations require extra tube, 2 bends and 4 soldered joint to be made, resulting in a lot of wasted time and a different finish for each installation. The Pipe Cowl changes all this by guaranteeing a neat finish every time, with one just fitting and one soldered joint.
