Low-Profile Seal Design by Polypac

Low-Profile Seal Design — Compact Performance from Polypac

Polypac specializes in Low-Profile Seal Design that balances minimal cross-section with maximum sealing performance. Our designs are optimized for confined assemblies and high-cycle hydraulic systems, providing reliable sealing with reduced friction and improved dynamic response. Ideal for aerospace, mobile hydraulics, and OEM equipment, our low-profile seals address modern demands where space and efficiency are critical.

Performance Benefits

Low-profile seals deliver lower friction, faster breakaway, and reduced stick-slip compared with bulkier profiles. Polypac’s engineering ensures consistent pressure handling, exceptional wear resistance, and extended service life even under fluctuating loads and temperatures. These benefits translate to improved system efficiency, reduced maintenance, and longer intervals between replacements.

Materials & Manufacturing

Rooted in advanced material science, Polypac manufactures low-profile seals from PTFE compounds and elastomers including NBR, FKM, silicone, EPDM, and FFKM. Our heritage in filled PTFE (bronze, carbon, graphite, MoS2, glass) enables hybrid solutions—PTFE running faces with elastomeric energizers—offering low friction and excellent chemical compatibility. Production takes place in our >10,000 m² facility equipped with industry-leading molding, machining, and testing equipment.

Customization & Application Flexibility

Every application is unique; Polypac offers tailored Low-Profile Seal Design services—from dimensional optimization to material selection and compound tuning. We collaborate with OEMs and research institutions to adapt seals for extreme temperatures, aggressive fluids, high speeds, and limited installation envelopes. Custom O-rings, rubber rings, and PTFE components are available to meet exacting specifications.

Quality Assurance & Testing

Quality is embedded in our workflow. Polypac applies rigorous testing protocols including pressure cycling, leakage rate analysis, tribological assessment, and dimensional inspection. Our partnerships with universities and labs ensure continual improvement and validation under real-world conditions, guaranteeing consistent performance for mission-critical systems.
