The Series SS5315L Straight Female Light Duty DIN Swivel x Male Light Duty DIN Reducer hydraulic adapters are made of durable stainless steel and designed to connect hydraulic systems with different sizes of DIN fittings. These adapters feature a 24° tapered throat angle in the male threads for a secure and tight connection. When the tube nut is tightened, it compresses a ferrule or cutting ring around the tube, creating a leak-free seal. The swivel feature allows for flexibility in positioning the connection, while the reducer function smoothly transitions between different sizes. Classified under Light Duty (L), these adapters are ideal for low-pressure applications, offering reliable and efficient fluid transfer in hydraulic systems.
