The Series SS9003 Straight Male BSPP x Male BSPT hydraulic adapters, made from stainless steel, are designed for secure connections between BSPP (British Standard Pipe Parallel) and BSPT (British Standard Pipe Tapered) fittings in high-pressure hydraulic systems. BSPP connections feature parallel threads and seal through metal-to-metal contact or with an O-ring, while BSPT connections use tapered threads that create a seal by thread deformation. BSPP and BSPT are similar to NPT but have different thread pitches and thread forms, making them non-interchangeable. The BSPP male connection, labeled "G," is comparable to NPSM but has a different thread pitch, while BSPT, labeled "R," has a tapered thread. Thread sealants are recommended for these connections to prevent leaks. These adapters are compatible with DIN Tube connections, meeting the ISO 8434-1 / DIN 2353 standard, ensuring versatility and reliability in fluid power systems.
