Plumbing fittings in BSP and metric

The plumbing range here covers compression fittings, ball valves, elbows, tees, reducers, and the olives and nuts that go with them. Most items are available in 15mm and 22mm compression sizes for copper pipework, and in 1/4 inch to 1 inch BSP thread sizes for threaded connections.

BSP (British Standard Pipe) is the thread standard used across UK domestic and light commercial pipework. BSPP threads are parallel; BSPT threads are tapered and seal by thread interference. Compression fittings work differently again — they don't rely on threads to seal, but on the mechanical deformation of an olive against the pipe surface. Understanding which connection type you need before ordering avoids the most common mistakes.

All common sizes are stocked. If you're working on an older system with unusual thread sizes, or mixing metric with BSP, contact our team — we can advise on adaptors and reducers to bridge the difference.

Frequently Asked Questions

Do you stock both BSP and metric plumbing fittings?

Yes. The range covers BSPP, BSPT and metric compression fittings. Most standard UK domestic and light commercial pipework uses BSP threads; metric sizes are common in European equipment and some industrial applications.

What is a compression fitting and how does it work?

A compression fitting connects copper or steel pipe without soldering. The pipe is inserted into the fitting body, and when the compression nut is tightened, an olive deforms around the pipe to create a watertight seal. No heat is required.

Can I use BSP fittings on copper pipe?

BSP is a thread standard, not a pipe material standard. Compression fittings that accept copper pipe can have BSP threads for connection to other components. Check whether you need the fitting to accept a pipe (compression end) or thread into another fitting (BSP end).

Do you stock fittings for 22mm and 15mm pipe?

Yes. Both sizes are standard in the range.
