Softer than standard Buna-N O-rings for 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.

Choose these O-rings for their adherence to strict military standards for material and construction.

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

Made of silver-plated 321 stainless steel, these O-rings can handle extreme pressure up to 11,000 psi. They resist grease, hydraulic oils, mineral oil, motor oil, and synthetic lubricants.

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

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.

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.

All of these O-rings meet MIL-R-83248C.

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.

Unlike silicone, the Viton® fluoroelastomer core will continue to ward of chemicals should the FEP casing wear away.

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.

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.

Made of Kalrez 6230, these O-rings are for use when high purity is essential, such as with food and semiconductors.

These fluorosilicone O-rings remain flexible at temperatures as low as -75° F. They resist ethanol, ethylene glycol, and isopropyl alcohol.

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.

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

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.

Made and bagged in an ISO Class 7 (Fed. Std. Class 10,000) clean room, these are the highest purity high-temperature O-rings we offer.

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

These O-rings withstand higher temperatures than standard EPDM O-rings.

Made of FDA-listed material for use with food and beverage.

Use these O-rings with metric sanitary fittings, which are also called aseptic fittings. Made of EPDM, they resist water, steam, ethanol, and ethylene glycol.

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

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

Made of FDA-listed material for use with food and beverage, this cord stock resists animal and vegetable oils, citric acid, sodium bicarbonate, and grease.

Harder than standard Viton® fluoroelastomer cord stock for better wear resistance.

The brown color of this cord stock makes it easy to identify.

This cord stock is made of FDA-listed material for use with food and beverage. It resists citric acid, diluted salt solutions, glycerin, and sodium bicarbonate.

This cord stock is softer and creates a better seal than standard silicone cord stock in low-pressure applications up to 400° F.

In addition to water and steam, this EPDM cord stock resists diluted salt solutions, ethanol, and isopropyl alcohol.

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

Softer than standard Buna-N O-rings for a better seal in low-pressure applications.

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

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

Able to withstand heat up to 450° F, these O-rings maintain a strong seal even when the temperature rises.

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.
