There are many different connection types all across the world, this post will help you identify and define UK, German and Japanese connections! This post is an excerpt from our new Thread ID & Measurement Guide.
British Standard Pipe (BSP) and BSPT (tapered) connections are comparable to NPT, except most sizes have a different thread pitch, plus the O.D.’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.
