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

When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements. These resist grease, hydraulic oils, and motor oil.

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.

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.

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

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.
