SAE O-Ring Boss (ORB) hydraulic adapters are crafted from pressure-resistant carbon steel, which is renowned for its resilience and durability in high-demand hydraulic settings. ORB adapters can also be used to convert to NPT (National Pipe Thread), JIC (Joint Industry Council) conforming to SAE J514 technical specifications, and NPSM (National Pipe Straight Mechanical). Each type is tailored with distinct threading and sealing designs to meet diverse hydraulic system needs. To further enhance their durability and corrosion resistance, these adapters are coated with a zinc-trivalent anti-corrosion plating.
