Static Seals

Rubber, PTFE, Metal, Bonded and Inflatable

In a static sealing applications there is no movement between sealing surfaces or between the seal surface and its mating surface.

The most common seal used in static sealing situations is the O-Ring, but in addition to these, Trelleborg Sealing Solutions offers a range of specialized static seals.

Airseal | Static Seals | Trelleborg

Airseals are tubular elastomer seals activated by internal pressurization (inflatable seals) with air, water or other media. Airseals are used wherever reliable sealing of accesses to plants, containers and rooms are required. They represent a technically improved alternative to the standard contact pressure seals and can be easily adapted to match the surface to be sealed.
