The Adaptall Series SS9007 Straight Male BSPP x Male NPT hydraulic adapters, made from high-quality stainless steel, are designed to provide reliable and durable connections in fluid and gas systems. The male NPT side uses tapered threads to create a metal-to-metal seal, which is ideal for single assembly applications but not recommended for frequent disassembly due to wear on the threads. On the other side, the male BSPP connection features parallel threads, similar to the American NPSM but with a different thread pitch, and uses metal-to-metal or metal and O-ring sealing for a leak-tight fit. These adapters are perfect for hydraulic systems that require secure, long-lasting connections in harsh environments.
