Single Lip Wiper Seals — Reliable Contamination Protection by Polypac

Single Lip Wiper Seals by Polypac

High-performance design

Our Single Lip Wiper is engineered to remove contaminants from piston rods and shafts efficiently while minimizing fluid loss. Designed for dynamic sealing environments, the Single Lip Wiper reduces abrasive wear and prevents dirt ingress, improving system reliability and reducing maintenance intervals.

Material and manufacturing excellence

Polypac manufactures Single Lip Wiper seals using High Quality elastomers and specialty composites. Beginning with our heritage in filled PTFE (bronze, carbon, graphite, MoS2, glass-filled), we've expanded to NBR, FKM, EPDM, silicone and FFKM for tailored compatibility. With a 10,000+ m² facility and 8,000 m² production space, our advanced equipment delivers consistent tolerances and repeatable performance.

Custom solutions for special conditions

Every application has unique demands. Polypac provides custom Single Lip Wiper dimensions, shore hardness and compound blends suited to extreme temperatures, aggressive fluids, or abrasive environments. Our R&D partnerships with universities and research institutes enable rapid development of bespoke sealing compounds and geometries.

Quality control and testing

Rigorous testing ensures every Single Lip Wiper meets performance targets. Our in-house testing capabilities simulate pressure, speed and contaminant exposure to validate longevity and sealing effectiveness. Traceability, batch control and material certifications are standard for critical applications.

Applications and benefits

Ideal for hydraulic cylinders, mobile equipment, construction machinery and industrial actuators, the Single Lip Wiper provides superior contaminant exclusion while preserving rod finish. Benefits include extended component life, reduced downtime, and lower lifecycle costs.
