Pneumatic Seals

Rod, Piston, Static and Compact Seals

Trelleborg Sealing Solutions supplies a number of seals, wear rings and scrapers / wipers specifically engineered for pneumatic applications, where cylinders and valves are actuated by air. Pneumatic seals operate in dynamic applications, often at high speeds, generally with rotary or reciprocating motions. In addition, where a standard product type is not suitable, custom solutions can be developed.
