SAE O-Ring Boss (ORB) threaded fittings are ideal for leak control in medium to high pressure applications. While SAE O-Ring adapters and JIC 37° fittings have the same straight threads, JIC fittings create a metal-to-metal fitting, and SAE O-Ring adapters are sealed on an o-ring. O-ring seals are the best type of seals in regards to leakage. Because the seal takes place at the o-ring and not the threads, SAE O-Ring adapters are reusable.
Made from #45 steel and are zinc plated. O-Rings are included on all male boss (O-Ring) ends. Buna-N, 90 durometer O-Ring is standard. Other compounds are available, please inquire by email.
