Extreme Service Rod Seal — Polypac High-Performance Hydraulic Seals

Extreme Service Rod Seal — Engineered Durability by Polypac

Polypac's Extreme Service Rod Seal category is designed for hydraulic systems that demand exceptional reliability in the harshest environments. Combining advanced filled-PTFE technology, High Quality elastomers, and precision molding, these rod seals minimize leakage, reduce friction, and extend cylinder life. Whether you're replacing OEM parts or specifying for new equipment, Polypac delivers performance-driven sealing solutions suited to heavy-duty mobile hydraulics, offshore rigs, mining machinery, and industrial presses.

Superior Materials and Construction

Polypac uses a broad portfolio of sealing materials—including bronze-, carbon-, graphite-, MoS2-, and glass-filled PTFE plus elastomers like NBR, FKM, EPDM, silicone, and FFKM—to match media, temperature and wear profiles. Our multi-component constructions and surface finishes are selected to optimize dynamic sealing, abrasion resistance, and low breakaway friction. Material selection and fill levels are tailored to balance conformability and extrusion resistance for extreme-service applications.

Engineered for Extreme Conditions

These rod seals are purpose-built for high-pressure, high-speed, and wide-temperature-range operation. The profiles control fluid film thickness and maintain sealing integrity under pressure spikes and rod misalignment. Compatibility spans mineral oils, synthetic fluids, water-glycols, and specialty media. Polypac designs emphasize reduced heat generation, stable frictional performance, and superior wear resistance to maximize uptime in continuous-duty installations.

Custom Solutions and Rigorous Testing

Polypac’s 10,000 m2 facility integrates advanced production lines and lab testing equipment to deliver custom rod seal geometries, compound developments, and rapid prototyping. We collaborate with universities and research institutes for material innovation and validate performance with endurance, abrasion, extrusion, and compatibility testing to meet client-specific service life targets.

Applications and Industry Use Cases

Ideal for construction and mining hydraulics, cranes, marine and offshore equipment, agricultural machinery, and industrial presses, Extreme Service Rod Seals protect critical actuators where failure is not an option. They reduce maintenance cycles and total cost of ownership through longer service intervals and fewer unscheduled shutdowns.
