Precision Actuator Seal — Reliable Sealing Solutions by Polypac

Overview

Polypac's Precision Actuator Seal product category focuses on high-accuracy sealing solutions for linear and rotary actuators used in hydraulics, aerospace, robotics, and industrial automation. The Precision Actuator Seal family is engineered to minimize leakage, reduce friction, and extend service life under high pressure, temperature and speed variations. As a scientific and technical hydraulic seal manufacturer, Polypac combines decades of material science with precision molding to meet demanding performance specifications.

Materials & Customization

We offer Precision Actuator Seal options in a broad range of materials, including filled PTFE variants (bronze, carbon, graphite, MoS₂, glass) and elastomers such as NBR, FKM, silicone, EPDM, and FFKM. Polypac's large custom rubber ring and O-ring factory enables tailored compound selection, dimensional customization and special coatings to suit low-friction, chemical-resistant or high-temperature applications. Custom sealing geometry and tolerances are available to optimize actuator responsiveness and minimize stick-slip.

Performance & Applications

Designed for precision motion control, our Precision Actuator Seal products deliver low hysteresis, consistent dynamic sealing and excellent extrusion resistance for high-pressure actuators. Typical applications include servo and proportional valves, linear cylinders, aircraft flight controls, medical actuators and subsea equipment. Polypac seals are engineered to maintain sealing integrity across repeated cycles and harsh environments, improving uptime and reducing maintenance costs.

Quality, Testing & R&D

Polypac maintains one of the most advanced production and testing facilities in the industry, with over 8,000 m² of factory space and a total site exceeding 10,000 m². Our in-house testing and long-term collaborations with universities and research institutions ensure each Precision Actuator Seal meets strict dimensional, material and endurance standards. We perform leakage, wear, friction and pressure-cycle testing to validate performance before delivery.
