British Standard Parallel Pipe (BSPP) fittings are used to connect hydraulic valves and pipe fittings establishing pipeline connections. BSPP fittings are a good choice for hydraulic systems because they are strong reliable and provide secure connections even at high pressure. They are used in automotive systems such as fuel and hydraulic systems where reliability and ease of maintenance are important. BSPP fittings are designed with straight threads and a bonded seal ring which helps to create a strong seal. The seal is formed by pressing a bonded seal like an O-ring against the flat face of the male fitting.

• Other uses for BSPP fittings:• Pneumatic systems: BSPP threads are used to connect pneumatic valves and pipe fittings. They are a good choice because they can create secure connections without leaks.• Low-pressure liquid transmission systems: BSPP threads are often used in low-pressure liquid transmission systems such as fuel and liquid supply pipelines.• Industrial equipment and machinery: BSPP threads are used to connect pipes and fittings for industrial equipment and machinery such as water pumps compressors filters and cylinders.• Automotive: BSPP threads are used in automotive systems such as fuel and hydraulic systems where reliability and ease of maintenance are important
