15mm Compression Fittings

Compression fittings are a very widespread standard in all manner of domestic and workplace plumbing and drainage applications. 15mm diameter compression fittings are an especially common size that fit many systems, and can usually be fitted simply with a spanner.

A majority of our 15mm compression fittings are stocked under our popular brand RS PRO line, we also sell equivalent versions supplied by Legris and Pegler Yorkshire.
