Made of Buna-N, these O-rings resist grease, hydraulic oil, and motor oil—plus mild chemicals and water.

Harder than standard Buna-N O-rings, these 90A durometer O-rings are more durable and wear resistant.

With four points of contact for a strong seal, these X-profile O-rings are often used in dynamic applications, such as on pistons and rotating shafts. Also known as Quattro seals and X-rings, they resist rolling and twisting better than round- and square-profile O-rings.

FDA compliant for direct contact with food, these Buna-N O-rings create a strong seal in food and beverage lines.

These Viton® fluoroelastomer O-rings resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.

With a 90A durometer, these O-rings are harder and more wear-resistant than standard Viton® fluoroelastomer O-rings. They hold up to the high pressures in fuel injectors and heavy duty hydraulic cylinders.

Also known as Quattro Seals and X-rings, these X-profile O-rings have four points of contact for a better seal in moving parts than round-profile O-rings. Since they require less compression to make a seal, they also last longer.

Made for demanding applications, these O-rings hold up to constant motion, repeated compression, and extreme temperatures. They’re often used for centrifugal pumps and high-pressure hydraulic valves in chemical processing systems.

An FEP casing protects these O-rings from moisture and harsh solvents such as acetone, methanol, and boric acid. If the casing wears away, the Viton® fluoroelastomer core will continue to ward off chemicals.

Made from PTFE, these O-rings withstand extreme temperatures and harsh chemicals such as acetone, fluorinated solvents, and ethanol.

Create seals in temperatures as low as -65° F. Made of fluorosilicone, these O-rings have the same chemical resistance as Viton® fluoroelastomer O-rings, but they’re more flexible in the cold.

Use these O-rings in temperatures up to 400° F. Made of Parker S1138 silicone, they’re pure enough for food or pharmaceutical applications—they’re USP VI certified.

Made of silicone, these O-rings can withstand temperatures up to 400° F or higher. They're FDA compliant for direct contact with food, so they're often used on hot food lines.
