O-Ring Materials

The O-Ring is a simple, ingenious and effective sealing device. Because of its simple construction, it is readily adaptable to limited-space applications. It provides a dependable dynamic and static seal through wide ranges of pressures and temperatures. Although O-Rings are manufactured primarily as hydraulic and pneumatic seals, they are also used as drive belts, friction devices, vibration dampers and retaining rings.

Our customer representatives can assist you in selecting the appropriate O-Ring seal design, elastomer group and specific compound for trouble-free sealing in your specific application.

large inventory of over 350 standard-size O-Rings, in a wide range of compounds, is available from Johnson Packings. Hundreds of specials can also be provided.
