BSP Adapters & Fittings
We stock one of the largest selections of British Standard Pipe (BSP) fittings that you will find anywhere outside of Great Britain!
Steel fittings are recommended for use in brake lines. Steel, brass, or aluminum fittings may be used in oil systems or when plumbing gauges.
Note: BSP nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. If you are not sure what size you need, check in our Threaded Plumbing Fitting Identification Guide or our Guide to BSP Fittings.

We stock fittings to adapt male AN or NPT to female BSP (British Standard Pipe) ports. If the port face is not chamfered for an O-ring seal, an aluminum crush washer or a Dowty seal is usually used.
