Our Series 5009S Straight Male Heavy Duty DIN x Female BSPP hydraulic adapters are designed to provide a strong, secure connection between DIN and BSPP threaded components in heavy-duty applications. The DIN side features a 24° tapered throat inside the male threads, where a tube nut is tightened, compressing a ferrule or cutting ring to form a reliable seal. These adapters are ideal for high-pressure systems, as they are built to handle tougher conditions. On the BSPP side, the female swivel fitting has a parallel thread that uses metal-to-metal contact or an O-ring to form a seal, similar to NPSM connections, but with different thread specifications. These adapters are crucial for systems where durability and secure fluid transfer are required in compact, space-efficient designs.
