When you want a simpler route for pressure-relief termination, Flowflex Pipe Cowl replaces a conventional assembly of extra tube, multiple bends and several soldered joints with one fitting and one soldered joint. That gives you a more straightforward product choice and can reduce time and associated labour on the job.

One fitting, one soldered joint

The value of Pipe Cowl is in the simpler assembly. Rather than building the termination from separate components, the fitting provides the route in one product with one soldered joint. It is a practical option when you want to reduce the number of parts and joints involved without turning the decision into a complicated product search.

A neat finish at the external wall

Pipe Cowl gives a neat finish at the external wall. The one-fitting, one-joint approach keeps the termination tidy at the wall and makes the finished appearance a clear part of the product proposition.

Choose the standard size and pack

The standard range includes 15mm and 22mm options. Start by comparing the current details for the 15mm Pipe Cowl 1 Pack and 22mm Pipe Cowl 1 Pack to identify the size required for your project.

For different pack formats, PlumbHQ also lists the 15mm Pipe Cowl 5 Pack and 22mm Pipe Cowl 5 Pack. Compare the current details for the exact size and pack format you need.

Extended Pipe Cowl for high-rise applications

The Extended Pipe Cowl 1 Pack is designed for high-rise applications. It can be installed from inside the building, avoiding external access arrangements such as scaffolding or abseiling. This gives you a practical access and planning advantage where that route is relevant to the project.

Product details that matter

The Pipe Cowl range is manufactured to BS EN 1254 and NHBC approved. These are useful product details to consider alongside the size, pack format and Extended option you need. For your project, compare the current product information for the exact option before making your selection.
