Also known as Boss O-rings, these are for use in tube fittings with a straight-thread connection. They're 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.

These temperature- and chemical-resistant O-rings prevent leaks in tube fittings that have a straight-thread connection, also known as O-ring boss fittings. Because they’re PTFE, these O-rings are slippery, won’t tear, and resist harsh chemicals such as acetone, fluorinated solvents, methanol, and boric acid. They’re also made of FDA-listed materials, so they’re safe to use in food production lines. However, they’re rigid, which makes them more difficult to install than flexible O-rings. They come in standard dash number sizes according to SAE AS568A.

Flexible even at temperatures as low as -80° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol. Also known as Boss O-rings, these O-rings work with tube fittings with a straight-thread connection, such as BSPP, UN/UNF, and most metric fittings.
These O-rings meet MIL and ASTM standards for the chemical and physical properties of fluorosilicone. They also meet SAE AS568A for standard O-ring sizing.
