Our Straight Female Light & Heavy Duty DIN x Male BSPP hydraulic adapters, made from carbon steel, are designed to connect hydraulic systems using DIN Tube fittings (ISO 8434-1 / DIN 2353 standard) and BSPP (British Standard Pipe Parallel) fittings. The DIN connection features a 24° tapered throat on the male fitting for a secure and durable connection. BSPP male fittings, with parallel threads, seal via metal-to-metal or metal-to-O-ring surfaces, creating a reliable, leak-tight seal. These adapters are commonly used in high-pressure hydraulic systems where sealing is achieved by thread distortion, and thread sealants are recommended for added security. The BSPP connection is similar to NPSM but with different thread pitch and dimensions, making it non-interchangeable. Thread sizes are marked with "G" for parallel threads (e.g., BSPP 1/4-19 = G 1/4), ensuring compatibility and leak-free performance when properly sealed.
