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

These hard O-rings offer better wear resistance than standard Buna-N O-rings.

When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements. These resist grease, hydraulic oils, and motor oil.

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

If these O-rings deteriorate, they can be picked up by metal detection systems.

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.

These hard O-rings offer better wear resistance than standard Viton® fluoroelastomer O-rings.

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.

Because one black O-ring looks just like another, these O-rings are brown for easy identification.

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.

In addition to resisting chemicals, such as benzene, butyl alcohol, and ethylene glycol, these Viton® fluoroelastomer ETP O-rings resist steam.

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.

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.

Inherently softer and more compressible than PTFE O-rings, these Kalrez 4079 O-rings have comparable chemical resistance.

Kalrez 6375 O-rings are preferred over Kalrez 4079 for chemical-processing environments and applications involving steam.

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.

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.

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

These silicone O-rings withstand temperatures up to 400° F or 450° F.

When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements. These O-rings withstand temperatures up to 450° 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 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.

These O-rings also resist ammonia, ethylene glycol, and isopropyl alcohol.

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.

This soft cord stock creates a better seal in low-pressure applications that standard neoprene cord stock.

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

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

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

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.

These assortments include a mix of EPDM O-rings that resist water and steam and silicone O-rings that resist temperatures up to 450° F.
