The Series 6605 Straight Male ORFS x Male DIN Tube Light Duty hydraulic adapters, made from carbon steel, are designed to provide a secure, leak-free connection in medium-pressure hydraulic systems. ORFS (O-ring Face Seal) fittings use an O-ring at the face of the fitting, creating a reliable seal when the O-ring is compressed between the fitting and the mating part. Made to SAE J1453 standards, these adapters feature Buna-N or Viton, 90 Durometer O-rings, ensuring long-lasting performance. The DIN Tube Light Duty side, compliant with ISO 8434-1 / DIN 2353, has a 24° tapered throat on the male fitting, allowing for precise identification when combined with a Metric thread. To ensure proper fitment, tube series and size are clearly marked on the tube nut, making these adapters ideal for use in a wide range of hydraulic applications.
