About O-Rings

Rigid and hard with a slippery surface, these PTFE O-rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and boric acid. They have a round profile and are suitable for a wide range of static and dynamic sealing applications.

Metric O-rings are sized to the actual measured inside diameter.
