The Series SS5315S Straight Female Heavy Duty DIN Swivel x Male Heavy Duty DIN Reducer hydraulic adapters are high-quality stainless steel components designed for robust, high-pressure hydraulic systems. These adapters feature a 24° tapered throat angle in the male threads, ensuring a secure, tight connection when a tube nut is tightened over the metric threads. This action compresses a ferrule or cutting ring around the tube, creating a leak-proof seal. The swivel design allows for flexible positioning of the connection, while the reducer function accommodates different sizes, ensuring smooth transitions in your hydraulic setup. Classified as Heavy Duty (S), these adapters are built to handle higher pressures, providing reliable performance and durability in demanding applications.
