Compression Couplings

Explore our range of compression couplings designed specifically for underfloor heating pipe.

What Is a Compression Coupling?

A compression coupling is used to securely join two sections of pipe. Each end of the fitting features a compression nut and an olive. When the nut is tightened onto the threaded body, it compresses the olive creating a watertight seal that prevents leaks.

What Size Are These Compression Couplings?

Our compression fittings are designed for 12, 15, 16, 17 or 20mm pipes. This covers the main UFH and plastic pipe sizes.

We also carry a 15-16mm reducer, which allows connection to 15mm copper pipe.

Popular Uses

Compression couplings are not only ideal for connecting pipework, they’re also commonly used to repair damaged sections of pipe caused by kinks or accidental punctures (screws or nails during flooring installation).
