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.

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.

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.

Heat treated, cleaned, and double-bagged in an ISO Class 5 clean room, these O-rings come ready for use in high-vacuum systems.

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 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.

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.

Also known as Boss O-rings, these O-rings are made for tube fittings with a straight-thread connection. They’re made of Viton® fluoroelastomer that meets MIL-R-83248 performance standards.

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.

Get the same chemical and heat resistance as Kalrez 4079 without the brand name. Even at 600° F, these FFKM O-rings resist a wide range of chemicals, including acetone, methyl ethyl ketone (MEK), potassium hydroxide, and most acids.

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

Softer and easier to compress than Viton® fluoroelastomer, this fluoroelastomer cord stock creates tighter seals on uneven surfaces.

Create seals for equipment used in food, beverage, or pharmaceutical lines—this cord stock is FDA compliant for direct contact with food. Made of Viton® fluoroelastomer, it resists benzene, ethylene glycol, and other harsh chemicals.
