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.

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

Rigid and hard with a slippery surface, these O-rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and boric nitric, and sulfonic acids.

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.
