Frequently Asked Questions
What is the difference between BSPP and BSPT threads?
BSPP (British Standard Pipe Parallel) has a cylindrical thread that requires an O-ring or bonded seal. BSPT (British Standard Pipe Tapered) has a conical thread that creates a seal through thread interference. BSPP is more common in hydraulic systems; BSPT is used in pneumatic and low-pressure applications.
