Rod Seal for Heavy Equipment Cylinders — Polypac Solutions

High-performance rod seal for heavy equipment cylinders

Polypac designs rod seals specifically for heavy equipment cylinders, delivering reliable sealing under extreme pressure, contamination, and vibration. Our rod seal for heavy equipment cylinders minimizes leakage, extends service intervals, and maintains consistent performance across a wide temperature range—critical for construction, mining, and agricultural machinery.

Advanced materials and tailored formulations

We use a broad portfolio of sealing compounds including filled PTFE variants (bronze, carbon, graphite, MoS2, glass) and elastomers like NBR, FKM, silicone, EPDM, and FFKM. This allows Polypac to match the best material to each working environment—resistance to hydraulic fluids, abrasion, and chemical attack—ensuring each rod seal for heavy equipment cylinders is optimized for durability and low friction.

Precision manufacturing and rigorous testing

Polypac’s 10,000+ m² facility, with 8,000 m² of production space, houses industry-leading production and testing equipment. Every rod seal for heavy equipment cylinders undergoes dimensional control, friction testing, and endurance cycles to meet OEM specifications and reduce unexpected downtime on the jobsite.

Customization for special working conditions

Whether the application requires extreme temperature tolerance, contaminated environments, or heavy side loads, Polypac provides customized rod seals and O-rings. We collaborate with universities and research institutes worldwide to develop tailored sealing solutions that solve unique performance challenges.

Applications and cross-industry reliability

Our rod seals are proven in excavators, loaders, cranes, hydraulic breakers, and other heavy-duty cylinders. Designed for easy installation and stable sealing under load, Polypac rod seals reduce maintenance cost and improve machine uptime.
