BSPP sizes range from ¼" through 1½" threads with multiple seal configurations including Inline and 90º Swivels.
BSPP (British Standard Parallel Pipe) swivels are most common in the UK, Europe, Asia, Australia, New Zealand, and South Africa. A parallel thread fitting uses a bonded seal ring. This bonded ring seal is sandwiched in between a shoulder on the male fitting and the face of the female fitting and is squeezed in place with no thread sealant required. Super Swivels ball bearing race design withstands heavy side loads preventing premature seal wear and leaks.
