Pneumatic Cylinder Seal Kits

Pneumatic cylinder seal kits package all the seals needed to rebuild a pneumatic actuator in one order. A complete double-acting cylinder kit typically contains a piston seal, a rod seal, two rod wipers and two cushion seals. Buying a matched kit simplifies procurement, ensures groove compatibility and reduces the risk of ordering the wrong profile for one sealing position. Kits fall into two main categories. OEM-style kits match the original manufacturer's profile and material specification, providing a direct replacement without changing groove dimensions or friction characteristics. Aftermarket kits maintain dimensional compatibility while often upgrading materials—such as switching the piston seal from NBR to TPU for longer wear life—or consolidating profiles to reduce inventory cost. Standard kits are available for ISO 15552 profile cylinders and ISO 6432 compact cylinders, organized by bore diameter. We also assemble kits for specific manufacturer series including SMC C96/CP, Festo DSBC/DNC and AirTAC SC/SU. For maintenance departments with large pneumatic fleets, we offer mixed bore-size bulk packs and annual supply agreements. Custom kits are assembled for proprietary, modified or obsolete cylinders when a drawing or sample is provided. This is common in specialized automation equipment where the original manufacturer no longer supplies seals. No minimum order quantity applies to standard compound custom kits.
