Complete Pneumatic Piston A complete double acting piston supplied to CETOP sizes. Comprised of a molded nitrile (NBR) piston head with vulcanized metal support ring. Fields of application include oily and non processed compressed air and dry oil free air. Non-standard Pneumatic Seal Standard seals are frequently not appropriate for non-reciprocating and high volume applications. As your development partner, we can work with you to design, develop and supply precision elements and sealing systems in accordance with your requirements. Pneumatic Glyd Ring® for Piston and Rod Double acting Glyd Ring® available as piston or rod seal comprising a slipper seal and an energizing O-Ring combined with less installation space required. Different possible material combinations (Turcon® PTFE / Zurcon® polyethylene with NBR or FKM O-Ring) provide suitable solutions for special pneumatic applications where great importance is attached to minimum static and dynamic friction, low stick-slip effects, high speed performance or wide temperature range. Pneumatic Piston Seal The pneumatic product range offers single and double acting seals for piston applications. Made from extremely wear resistant material (standard polyurethane, Zurcon® polyurethane, FKM), these seals fit into small housings and are easily installed. The pneumatic piston seals range is recommended for standard and pneumatic cylinders with dry air.
