Series 9038ES Straight Male BSPP x Female BSPP hydraulic adapter bushings, made from carbon steel and equipped with elastomeric seals, provide a secure connection in hydraulic systems using British Standard Pipe Parallel (BSPP) threads. These adapter bushings are designed to handle high-pressure applications, ensuring leak-proof sealing through a combination of metal-to-metal contact and a flexible elastomeric O-ring. While similar to NPT, BSPP threads differ in pitch and form, requiring thread sealants for a tight fit. The female swivel BSPP fitting features a tapered nose flareless swivel, ensuring the seal occurs on the cone seat of the male connector. These bushings are ideal for systems that require reliable and durable sealing with an added elastomeric seal for extra leak protection. The thread sizes are marked with "G" for parallel threads, such as G 1/4 for BSPP 1/4-19.
