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

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

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.

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

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

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