Compression Straight Couplers

Brass compression straight couplers in sizes 4–54mm.

Compression plumbing fittings do not require solder.

The joint is formed by tightening a nut and olive onto a pipe, compressing the olive onto a copper or plastic pipe which forms the seal.

They can be used on wet pipework, and are suitable for hot and cold systems.
