  • Boss 900 Series O-Rings | O-Ring Boss Seal

An O-ring boss seal is primarily used to join pipes, hoses or tubes that transfer fluid. One of the main benefits of utilizing an O-ring boss seal over other connection systems is that a boss O-ring can be mechanically tightened with a nut into a chamfered area before being sealed.
