Oil-Resistant Hard Buna-N O-Rings for Tube Fittings with SAE Straight-Thread Connection

SAE J1926-1

Also known as Boss O-rings, these are for use in tube fittings with a straight-thread connection. They are made of hard Buna-N, which is resilient and offers excellent resistance to wear, grease, petroleum fluids, and motor oil. These O-rings have a round profile and are suitable for a wide range of static and dynamic sealing applications. They're sized to the SAE standard AS568.

Recommended by the NFPA for optimal leakage control in medium and high pressure hydraulic systems. The male fitting has a straight thread and O-ring. The female port has a straight thread, a machined surface (minimum spotface) and a chamfer to accept the O-ring. The seal take place by compressing the O-ring in the chamfer. The threads hold the connection mechanically. This fitting is also known as O-Ring Boss (ORB) and uses these Boss O-Rings.
