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.

Also known as boss O-rings, these O-rings are sized to fit straight threaded fittings to prevent leaks. With a 90A durometer hardness, they’re more wear resistant than standard Buna-N O-rings.

These Buna-N O-rings are made of FDA-listed material for use with food and beverage.

These Buna-N O-rings are made and bagged in an ISO Class 7 (Fed. Std. 10,000) clean room.

More abrasion resistant than Buna-N O-rings, these also resist mineral oil and motor oil.

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

Softer than standard Viton® fluoroelastomer O-rings, these offer a better seal in low-pressure applications.

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

Use these O-rings with metric sanitary fittings, which are sometimes called aseptic fittings. Made of Viton® fluoroelastomer, these O-rings resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.

These durable O-rings bounce back to shape after repeated compression better than other types of Viton® fluoroelastomer O-rings.

These are the highest purity chemical-resistant O-rings we offer. They are made and bagged in an ISO Class 7 and Fed. Spec. Class 10,000 clean room, plus they’re USP VI certified; not for use in medical applications.

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

Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection. They meet MIL-R-83248.

Rigid and hard with a slippery surface, these PTFE O-rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and boric acid.

Pair these O-rings with metric sanitary fittings, which are commonly known as aseptic fittings. Made of PTFE, they’re rigid with a slippery surface and resist harsh chemicals such as acetone, fluorinated solvents, methanol, and boric acid.

The FEP casing on these O-rings provides the same level of resistance to harsh chemicals as PTFE O-rings, but the core material is soft to make these O-rings more compressible.

Able to bounce back after repeated compression, these Kalrez 7075 O-rings last longer than other Kalrez O-rings when exposed to repeated heating/cooling cycles.

Also known as Boss O-rings, these Kalrez 4079 O-rings are for use in tube fittings with a straight-thread connection. They’re inherently softer and more compressible than PTFE O-rings with comparable chemical resistance.

While these Aflas O-rings are commonly used with petroleum fluids, they also resist many chemicals, such as ammonia, calcium hydroxide, and acetic, boric, and phosphoric acids.

Flexible even at temperatures as low as -75° 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.

Able to withstand temperatures up to 400° F, these O-rings are softer than standard silicone O-rings for a better seal in low-pressure applications.

When you need a silicone O-ring that’s not an industry standard size, we can make one to fit your requirements. These O-rings withstand temperatures up to 400° F.

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

These O-rings also resist ethanol and ethylene glycol.

When you need an EPDM O-ring that’s not an industry standard size, we can make one to fit your requirements.

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

Resistant to changing weather—from rainwater to sunlight—these neoprene O-rings are good for outdoor use.

Harder than standard Buna-N cord stock for better wear resistance.

This cord stock resists benzene, boric acid, ethylene glycol, and isopropyl alcohol.

This cord stock is softer and creates a better seal in low-pressure applications than standard fluoroelastomer cord stock.

More chemical resistant than standard Viton® fluoroelastomer, this cord stock is made of Grade ETP Viton® fluoroelastomer. It resists harsh chemicals, such as calcium hydroxide, methyl ethyl ketone (MEK), and nitric and phosphoric acids.

Use this cord stock to create O-rings for high-temperature applications up to 400° F.

Create round-profile O-rings for sealing applications near ovens and other hot areas in your food plant.

Use neoprene cord stock to make O-rings for applications that come into contact with water.

All of the O-rings in these assortments are made of Buna-N. They resist animal, vegetable, and motor oils.

These O-rings are harder than standard Buna-N O-rings for better resistance to wear.

These assortments contain a mix of Buna-N O-rings that resist oil and Viton® fluoroelastomer O-rings that resist boric acid, fuels, and transmission fluid.

Also known as Boss O-rings, these hard Viton® fluoroelastomer O-rings are for use in tube fittings with a straight-thread connection. They offer excellent resistance to wear.

In addition to water and steam, these EPDM O-Rings resist ethanol and ethylene glycol.
