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 O-rings are harder and stronger than standard polyurethane O-rings to handle high-pressure applications.

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 for use in semiconductor manufacturing, food processing, and other highly controlled applications. More pure than Kalrez 4079 O-rings, these Kalrez 6230 O-rings won’t leach contaminants into your line.

Often used in drilling systems, these Aflas O-rings hold up to petroleum fluids. They also withstand steam and chemicals such as ammonia, calcium hydroxide, and boric acid.

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.
