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. Trelleborg's range of pneumatic seals includes: Pneumatic rod seals Piston seals Rod seal - scraper combinations Static seals Pneumatic scrapers Wear rings and cushioning seals Any Trelleborg pneumatic seal is manufactured in optimized materials including Zurcon® polyurethane andTurcon® Polytetrafluoroethylene (PTFE) based material.
