Static Seals

Static Seals - Rubber, PTFE, Metal, Bonded and Inflatable

In a static sealing application 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.The range includes our proprietary metal O-Rings, Wills Rings® , which are ideal for use in extreme temperatures and pressures. Other static seals we offer include inflatable seals (Airseal), various rubber seals, valve seals, x-rings, square rings, rubber - metal bonded seals, polyurethane seals and spring energized Polytetrafluoroethylene (PTFE) seals.
