Rod Seal Solutions for High Pressure Application — Polypac

Rod Seal High Pressure Application Solutions by Polypac

Overview: engineered for demanding environments

Polypac designs rod seals for high pressure application, delivering reliable sealing in hydraulic cylinders, mobile machinery and industrial equipment. Our seal category emphasizes long service life, low friction and consistent performance under cyclic loads and pressure spikes. Whether retrofitting existing systems or specifying seals for new designs, Polypac provides solutions that reduce downtime and operating costs.

Materials & performance: advanced compounds for extreme duty

We leverage decades of materials science expertise, offering filled PTFE variants (bronze, carbon, graphite, MoS₂, glass) and high-performance elastomers (NBR, FKM, silicone, EPDM, FFKM). These formulations are optimized for sealability, wear resistance and thermal stability—critical attributes for any rod seal high pressure application. The result: minimal extrusion, excellent chemical compatibility and superior friction control across temperature ranges.

Customization & testing: tailored designs, validated results

Polypac’s 10,000+ m² manufacturing hub and advanced testing lab enable rapid prototyping and rigorous validation. We customize cross-sections, lip geometry and backup designs to suit pressure, speed and fluid type. Each rod seal undergoes pressure cycling, extrusion resistance and friction testing—ensuring the component meets specified performance targets for your high pressure application.

Applications & industries: where our rod seals excel

Our rod seals are widely used in construction, mining, oil & gas, marine hydraulics and aerospace ground equipment. The seals perform under high static and dynamic pressures, in contaminated environments and where long intervals between service are required. Polypac’s solutions improve system reliability and help OEMs meet stringent uptime and safety requirements.
