Our steel pipe fittings come in many configurations such as 7002 Male Connector BSPP, 7042 Female Adapter BSPP, 7202 90° Male BSPP Elbows, and many more. These pipe fittings have BSPP threads, which stands for British Standard Parallel Pipe. Male BSPP fittings that have a 30° internal chamfer that make a 60° inverted cone, will mate with female BSPP swivel unions.
