Single-Acting Piston Seal — Polypac Custom Hydraulic Seals

Polypac Single-Acting Piston Seal Solutions

Overview

Polypac manufactures High Quality Single-Acting Piston Seal designs for hydraulic cylinders where reliable return or pressurization control is essential. Leveraging 15+ years of experience in sealing material development and precision production, our seals deliver stable performance across a wide range of temperatures, pressures, and environments.

Materials & Performance

Our Single-Acting Piston Seal lineup uses advanced filled PTFE (bronze, carbon, graphite, MoS₂, glass) and elastomers including NBR, FKM, EPDM, silicone, and FFKM. These material combinations optimize friction, wear resistance, chemical compatibility, and extrusion resistance—ensuring long service life and consistent sealing under dynamic loads.

Customization & Manufacturing

Polypac’s 10,000+ m² facility with 8,000 m² of production space houses industry-leading machining and testing equipment. We offer tailored Single-Acting Piston Seal profiles, compound formulations, and dimensional tolerances to meet unique working conditions—thermal extremes, contaminated fluids, or space-constrained cylinders.

Applications

Designed for construction machinery, mobile hydraulics, industrial presses, and marine actuators, our Single-Acting Piston Seals provide reliable sealing for single-direction pressure cycles. Typical benefits include reduced leakage, lower wear rates, and improved energy efficiency.

Installation & Maintenance

Polypac seals are engineered for straightforward installation and predictable maintenance intervals. Proper groove design, lubrication recommendations, and inspection schedules reduce downtime and extend component life. We provide technical drawings and installation support for seamless integration.
