We stock these O-ring coupler fittings to join two female ORB parts together. This includes adapting a fuel filter to fuel pump, regulator to fuel rail and other such instances.
The O-Ring Boss (ORB) is a UNF Thread with a o-ring recess cut into it for sealing. It is now very common to find oil and fuel pumps, filters & regulators to be machined this way for a much more secure seal.
