The Series 9018 Straight Swivel Male Metric x Female BSPP Hydraulic Adapter is designed for secure and flexible connections in hydraulic systems. It features a male metric thread, a common type of foreign thread used in Europe, with outer diameter and thread pitch measurements specified in millimeters, such as M22x1.5. The female BSPP side has a parallel thread and is equipped with a swivel design, allowing for easy adjustment and orientation of the fitting without causing stress or leakage. The BSPP connection relies on a metal-to-metal seal or a combination of metal and an O-ring, ensuring a tight, leak-free fit. This adapter is ideal for applications requiring a reliable, flexible connection between male metric and female BSPP fittings in fluid power systems.
