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.

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.

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.

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.

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

Made and bagged in an ISO Class 7 and Fed. Spec. Class 10,000 clean room.

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.

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

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.

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.

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.

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length.

Built for small circulation and dispensing pumps, these seals have short springs.
