O-Ring Adapters

O-Ring Boss (abbreviated ORB) is frequently used in hydraulics. The male-threaded part connects with a female-threaded part, although an o-ring creates the fluid-tight seal.
O-Ring Face Seal (abbreviated ORFS) sometimes called Flat Face O-Ring or For-Seal - is another popular connection used in hydraulic systems.
O-Ring fittings and adapters are designed and built to resist high pressure leakage and are made for higher pressures than is typically experienced in general plumbing systems.
