Is the Seal kit for ISO 21287 pneumatic cylinder Ø20/25, polyurethane, LINER series compatible with both single- and double-acting compact actuators?

Yes. The Seal kit for ISO 21287 pneumatic cylinder Ø20/25, polyurethane, LINER series is engineered for maximum compatibility with compact actuators and is suitable for both single- and double-acting configurations. Its durable polyurethane construction and precise sizing (Ø20 and Ø25) ensure reliable sealing, wear and pressure resistance, and smooth operation in either actuator type. Easy installation and ISO 21287 compliance make it a straightforward replacement to maintain performance and reduce downtime for both single- and double-acting compact actuators.

Can the Seal kit for ISO 21287 pneumatic cylinder Ø20/25, polyurethane, LINER series withstand exposure to hydraulic fluids or aggressive lubricants?

Seal kit for ISO 21287 pneumatic cylinder Ø20/25, polyurethane, LINER series is engineered primarily for pneumatic applications and is made from durable polyurethane offering excellent wear and pressure resistance in demanding working conditions. Polyurethane provides good general chemical resistance, but compatibility with hydraulic fluids and aggressive lubricants depends on their specific chemistry and additives. For typical mineral-based hydraulic oils and common pneumatic lubricants, polyurethane often performs acceptably; however, exposure to aggressive hydraulic fluids (e.g., phosphate esters, certain synthetic esters, strong solvents, ketones, aromatic hydrocarbons) or aggressive additives can cause swelling, softening, or accelerated wear of polyurethane seals. Recommendation: do not assume universal compatibility. Verify the exact fluid/lubricant type and consult the fluid manufacturer’s compatibility data or perform a compatibility test. If the system uses aggressive hydraulic fluids or uncertain lubricants, choose seals made from materials specifically rated for those fluids or contact the manufacturer for a recommended alternative.
