The Series 9234 Straight Rigid Male Metric x Female BSPT Hydraulic Adapter is a robust connection designed to join hydraulic systems with metric and British Standard Pipe Tapered (BSPT) threads. The male end features metric threads, commonly used in Europe, with measurements in millimeters (e.g., M22x1.5), where "M" indicates metric, "22" is the outer diameter in millimeters, and "1.5" is the thread pitch. The female end is BSPT, a tapered thread type used to seal pipes in fluid power systems. BSPT threads create a secure seal by distorting the threads when tightened, making the use of thread sealants essential for ensuring leak-proof connections. The key difference between BSPT (tapered threads) and BSPP (parallel threads) lies in their design: BSPT features a taper, which allows for a tighter, more secure seal, whereas BSPP has parallel threads that require additional sealing methods such as O-rings. This hydraulic adapter is made of carbon steel, ensuring durability and strength for high-pressure applications.
