Stainless Steel SAE O-Ring Boss Fittings ( ORB )

Stainless SAE O-ring boss fittings use straight thread and an O-ring (of either Buna N or Viton material, depending on the type of hydraulic fluid) to create a seal between the male and female fitting. Compression of the male fitting O-ring into the female chamfer cone seat creates a strong leak proof connection. SAE ORB adapter fittings are an excellent choice for medium and high pressure applications.
