UL Wiper Seal: Reliable Protection for Hydraulic Systems

Why Choose Polypac UL Wiper Seal

Polypac's UL Wiper Seal is engineered to keep contaminants out of hydraulic cylinders and extend the life of rod seals and bearings. Since 2008 we have specialized in high-performance sealing solutions—combining scientific research, advanced production lines and industry-leading testing to deliver wipers that meet stringent reliability demands. Choosing a UL Wiper Seal from Polypac means selecting a partner with a 10,000+ m² facility, expert R&D collaborations and a record of supply to demanding industrial applications.

Materials & Compatibility

Our UL Wiper Seal range is available in multiple compounds for optimized compatibility: carbon- and bronze-filled PTFE variants, MoS₂ and graphite-filled PTFE for low-friction environments, and elastomers such as NBR, FKM, EPDM, silicone and FFKM for chemical resistance and temperature extremes. Material selection for each UL Wiper Seal is driven by fluid type, pressure, temperature and surface finish to ensure reliable wiping performance and minimal rod wear.

Custom Manufacturing & Precision Testing

Polypac's custom rubber ring and O-ring factory covers more than 10,000 m² with 8,000 m² of production space. We offer tailored UL Wiper Seal geometries and tolerances for unique cylinders and special conditions. Our advanced production and testing equipment enable dimensional control, abrasion testing and endurance trials—delivering consistent quality and traceability for every batch.

Applications & Performance Benefits

UL Wiper Seal solutions are ideal for hydraulic and pneumatic systems across mobile equipment, industrial presses, marine hydraulics and high-cycle automation. Key benefits include superior contamination exclusion, reduced maintenance intervals, decreased rod scoring and enhanced system uptime. Our designs focus on effective debris shedding, minimal friction and reliable sealing even under variable loads.
