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

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.

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.

These fluorosilicone O-rings remain flexible at temperatures as low as -60° F. They resist ethanol, ethylene glycol, and isopropyl alcohol.

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.

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

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.

Also known as Quattro Seals and X-rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O-rings. They also require less compression to make a seal, so they offer a longer service life.

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

With flat edges on all four sides, square-profile O-rings cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections.

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

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.

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

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.

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

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

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

These O-rings also resist ethanol and ethylene glycol.

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

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

Made of Buna-N, these backup rings resist grease, petroleum fluids, and motor oil.

Place an O-ring onto one of these plastic sizing cones to determine the size of your O-ring.

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

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.

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

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

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

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

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

This square-profile cord stock has flat edges on all four sides, which creates a better seal than round profile in static applications, such as hose, pipe, and faucet connections.

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

This square-profile cord stock has flat edges on all four sides, which creates a better seal than round profile in static applications, such as hose, pipe, and faucet connections.

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

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

Also known as O-ring vulcanizing kits, these use a combination of heat and adhesive to create a bond that’s stronger with greater elasticity than a bond made of adhesive alone.

The X shape of this cord stock provides four points of contact for a better seal in dynamic applications than round profile. It also requires less compression to make a seal, so it offers a longer service life.

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