The Series 3474-NWO-SS Straight Male Adjustable ORB x Male ORB hydraulic adapters, made from stainless steel, are an adjustable version of the standard 6464-O series, offering enhanced flexibility for fluid power systems. These ORB (SAE Straight Thread O-ring Boss) fittings feature a male connection with a straight UNF thread and an O-ring, providing a reliable leak-tight seal when compressed into the chamfer of the mating female connection. The female port has a straight thread with a precisely machined surface, ensuring smooth and accurate alignment for secure connections. Commonly used in medium to high-pressure hydraulic systems, these fittings are manufactured in durable stainless steel and equipped with Buna-N or Viton 90 Durometer O-rings, as recommended by the NFPA for leak prevention. They offer long-lasting, effective sealing solutions in fluid power applications.
