Single-Acting Seal Solutions by Polypac

Overview

Polypac's Single-Acting Seal range addresses the core needs of hydraulic and rotary systems where sealing is required in one direction of movement. Designed for robust sealing under unidirectional pressure, our Single-Acting Seal products deliver consistent performance in cylinders, pumps, and actuators. Leveraging over a decade of material science and manufacturing expertise, Polypac integrates advanced polymers and elastomers to meet diverse operating conditions.

Materials & Performance

Our Single-Acting Seal portfolio includes filled PTFE variants (bronze, carbon, graphite, MoS₂, glass) and elastomers such as NBR, FKM, EPDM, silicone, and high-performance FFKM. These material options allow you to balance friction, wear resistance, chemical compatibility, and temperature stability. Polypac optimizes compound selection to minimize leakage, extend service life, and reduce maintenance intervals for your equipment.
