Straight Male ORB x Male ORB hydraulic adapters are designed to provide reliable, leak-free connections in medium and high-pressure hydraulic systems. ORB (SAE Straight Thread O-ring Boss) fittings feature a straight UNF thread with an O-ring, creating a secure seal when the O-ring is compressed into a chamfered surface on the mating port. The female connection also has a straight thread and a precisely machined surface for accurate alignment, ensuring optimal performance. Typically made from carbon steel, nickel-plated carbon, or stainless steel, these adapters utilize Buna-N or Viton 90 Durometer O-rings to form an elastomeric seal. Recommended by the National Fluid Power Association (NFPA), they are ideal for preventing leaks in hydraulic systems while providing easy assembly and disassembly.
