Shop 6464-O Straight Male ORB - Male ORB

Series 6464-O Straight Male ORB x Male ORB hydraulic adapters provide secure, leak-free connections for medium and high-pressure hydraulic systems. ORB (SAE Straight Thread O-ring Boss) fittings are designed with a male connection featuring a straight UNF thread and an O-ring that creates a tight seal when compressed into the chamfer of the mating port. The female port has a straight thread with a precisely machined surface, ensuring a smooth, flat surface for accurate alignment. Made from durable carbon steel, these adapters commonly use Buna-N or Viton 90 Durometer O-rings for elastomeric sealing. Recommended by the NFPS, they prevent leaks and ensure optimal performance in fluid power systems.
