Boss Fittings

When connecting two fluid-carrying tubings, hoses, or pipes, one of the common methods is using an O-ring boss seal. Boss fittings are plumbing fittings used on o-ring boss systems (ORB), where the male parts are inserted into threaded female parts to provide a mechanical seal. Boss fittings and O-ring boss system differ from other types of fittings in that an additional nut is tightened over the O-ring to form a fluid-tight seal. Although boss fittings are in most of the cases used in hydraulics, they are also applied in other systems such as compressed air systems in vacuum pumps like the Robinair pump. In the case of the Robinair pump, the intake seal is designed with an O-ring seal at the bottom. Boss fittings are also recommended for hydraulic systems where leaks and failure are not tolerable.
