Series SS5001S Straight Male Heavy Duty DIN x Male BSPP Form B hydraulic adapters, made from stainless steel, offer a robust solution for high-performance hydraulic systems. The Form B design utilizes a metal-to-metal seal, which is cut into the spot face port side to create a durable, cost-effective connection, especially in high-heat environments where Viton seals may not be reliable. These adapters are compatible with DIN Tube fittings, adhering to the ISO 8434-1 / DIN 2353 standard, with a 24° tapered throat on the male fitting for a secure connection. On the BSPP (British Standard Pipe Parallel) side, the male fitting features parallel threads that mate with the female BSPP fitting to create a leak-tight seal, often with a combination of metal-to-metal or metal-to-O-ring sealing. The connection is similar to NPSM but uses different thread pitches and dimensions, so it's non-interchangeable. Thread sizes are marked with "G" for parallel threads, such as BSPP 1/4-19, and thread sealants are recommended for a reliable, leak-free seal.
