The Series 3474-LLL-NWO Straight Male Adjustable ORB x Male ORB hydraulic adapters, made of carbon steel, are an adjustable and extra-extra-long version of the standard 6464-O series, designed for flexible and secure fluid power connections in medium to high-pressure systems. These ORB (SAE Straight Thread O-ring Boss) fittings feature a male connection with a straight UNF thread and an O-ring, ensuring a leak-tight seal when the O-ring is compressed into the chamfer of the mating female connection. The female port has a straight thread with a precisely machined surface to ensure smooth, accurate alignment. Manufactured in durable carbon steel and equipped with Buna-N or Viton 90 Durometer O-rings, these fittings meet the NFPA standards for leak prevention, providing reliable sealing performance in demanding hydraulic applications.
