Polypac Piston Rod Seal Supplier — Custom Hydraulic Seals

Piston Rod Seal Supplier — High Quality Sealing Solutions by Polypac

Trusted piston rod seal supplier

As a specialist piston rod seal supplier, Polypac delivers high-performance seals engineered for reliability in hydraulic cylinders and mobile equipment. Founded in 2008, we combine two decades of materials science and manufacturing experience to provide seals that reduce leakage, extend rod life, and withstand harsh environments.

Factory scale and production capabilities

Polypac operates a custom rubber ring and O-ring factory exceeding 10,000 square meters with 8,000 square meters of production space. Our production lines and automated molding systems are among the most advanced in the industry, enabling consistent quality and rapid volume scaling for OEM and aftermarket customers.

Advanced materials and custom formulations

We began with specialized filled PTFE seals (bronze, carbon, graphite, MoS2, glass) and have expanded to diverse elastomers including NBR, FKM, silicone, EPDM, and FFKM. Our R&D team develops tailored compounds and composite designs to meet unique friction, temperature, and chemical-resistance requirements.

Industry-grade testing and research partnerships

Polypac maintains rigorous testing protocols—wear, extrusion, pressure, and dynamic leakage tests—backed by long-term collaborations with universities and research institutes domestically and internationally. These partnerships ensure our piston rod seals meet global performance and safety standards.

Applications and performance advantages

Our piston rod seals are engineered for hydraulic cylinders in construction machinery, mining, agricultural equipment, and industrial presses. Benefits include improved sealing under high pressure, reduced maintenance intervals, and optimized lifetime cost through material selection and precision manufacturing.
