# BSPT — Hydraulic and pipe connection type identification

For BSPT, governing standard is BSP; region of origin is British Connections; thread type (tapered or parallel) is tapered; seal method is Sealing takes place by distortion of the threads; interchangeability notes is comparable to NPT, except most sizes have a different thread pitch, plus the OD's and thread form are close, but not the same, recorded from its source on 2026-08-13.

## What the source says

> British Connections British Standard Pipe (BSP) and British Standard Pipe Tapered (BSPT) connections are comparable to NPT, except most sizes have a different thread pitch, plus the OD’s and thread form are close, but not the same. Sealing takes place by distortion of the threads. Because of this, thread sealants are recommended when securing these connections.
