Stainless Steel SAE O-Ring Boss (ORB) Hydraulic Adapter Fittings
SAE O-ring boss fittings use straight thread and an O-ring (Buna N or Viton 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 very leak resistant connection. SAE ORB adapter fittings are an excellent choice for medium and high pressure applications. Stainless steel fittings are used for applications requiring maximum corrosion or sanitary protection.
