Product Description
This Stainless Steel ORB #12 Single Thru-Deck Fitting can't be beat!
An O-Ring Boss Seal is a technique for joining two fluid-carrying pipes, hoses or tubing. In an O-ring boss (abbreviated ORB) system, a male-threaded part is inserted into a female-threaded part, providing a mechanical seal. This system differs from others in that an additional nut is tightened over an O-ring into a chamfered area, creating a fluid-tight seal.
