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.

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.

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.

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.

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

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.
