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.

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.

Made of silicone, these O-rings withstand temperatures up to 400° F. They have flat edges on all four sides, so they cover more surface than round-profile O-rings.

Also known as boss O-rings, these O-rings are sized to fit straight-thread fittings to prevent leaks.

If these O-rings deteriorate and fall in your line, they’ll be caught by metal- and X-ray-detection systems.

Also known as Boss O-rings, these Viton® fluoroelastomer O-rings are made for tube fittings with a straight-thread connection. With a 90A durometer, they’re harder and more durable than standard Viton® fluoroelastomer O-rings.

Made of Viton® fluoroelastomer, these O-rings won’t degrade when exposed to chemicals such as sulfuric acid, butyl alcohol, and ethylene glycol. They’re also FDA compliant for direct contact with food.

Tested to meet ASTM E595, a standard used by NASA, these O-rings give off almost no volatile emissions that could damage sensitive electronics, even in a vacuum. They’re softer than standard Viton®, so they better conform to irregular surfaces.

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.

Also known as Boss O-rings, these O-rings are made for tube fittings with a straight-thread connection. Made of Viton® fluoroelastomer, they resist a variety of chemicals, including benzene, butyl alcohol, and ethylene glycol.

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 of our hardest Viton® fluoroelastomer, these O-rings can handle sudden pressure changes that would cause softer O-rings to crack or deform.

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

Our most chemical-resistant Viton® fluoroelastomer O-rings. Made of Viton® ETP, these O-rings stay strong when used with harsh chemicals including acetone, MEK, and sodium hydroxide. They also keep their elasticity and shape under constant motion in steam and heat.

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 made for tube fittings with a straight-thread connection. They’re fluorosilicone, which stays flexible in temperatures as low as -65° F, so they form better seals than Viton® fluoroelastomer O-rings in cold environments.

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

Seal lines and valves in HVAC systems, freezers, and other cold applications exposed to chemicals. Made with an FEP casing, these O-rings are protected against chemicals such as methanol and boric acid.

Keep a range of sizes on hand so that you always have the O-ring you need.

Keep a variety of O-rings on hand, so you always have the size you need. The O-rings in these assortments have flat edges on all four sides, so they cover more surface than round-profile O-rings.

All of the O-rings in these assortments are Viton® fluoroelastomer and resist isopropyl alcohol, mineral oils, and transmission fluid.

Often used to seal ovens and other food processing equipment, this silicone cord stock withstands heat up to 450° F. It’s made with metal and chemical additives that will set off metal detectors and X-ray machines if a piece falls into your line.

Easier to compress than standard silicone cord stock, this cord stock creates a better seal on uneven surfaces. It withstands temperatures as low as -60° F and as high as 400° F.
