Silicone O-Ring Kits — Reliable Sealing Solutions from Polypac

High Quality Silicone O-Ring Kits

Polypac’s Silicone O-Ring Kits deliver high-performance sealing designed for temperature resilience, excellent compression set resistance, and long-term reliability. Our kits are ideal for maintenance teams, OEMs, and service warehouses that need stocked, ready-to-use silicone O-rings for a wide range of hydraulic and pneumatic applications. Each kit is organized by size and shore hardness to simplify installation and reduce downtime.

Custom Manufacturing & Advanced Facilities

As a scientific and technical hydraulic seal manufacturer, Polypac operates a custom rubber ring and O-ring factory covering over 10,000 m² with 8,000 m² of production space. Our production and testing equipment are among the most advanced in the industry, enabling precise molding and tight tolerances. Founded in 2008, we combine industrial production capacity with R&D collaboration across leading universities and research institutes.

Material Expertise & Expanded Product Range

While our origins are in filled PTFE seals (bronze, carbon, graphite, MoS₂, glass), today Polypac offers O-rings in NBR, FKM, Silicone, EPDM, and FFKM. Our Silicone O-Ring Kits benefit from tailored compound formulations to meet specific temperature ranges, chemical exposures, and sealing pressures. We provide custom shore hardness and color coding for easier identification and inventory control.

Quality Assurance & Testing

Rigorous quality control is core to every Silicone O-Ring Kit. Polypac performs dimensional inspection, hardness testing, compression set, and aging analyses to ensure consistent performance. Our material traceability and batch testing give you confidence in critical applications, from laboratory instruments to heavy-duty hydraulic systems.

Applications & Key Benefits

Recommended for aerospace support systems, medical devices, food-grade equipment (with appropriate compounds), and industrial hydraulics, our Silicone O-Ring Kits offer wide temperature stability, excellent sealing under oscillatory motion, and resistance to ozone and UV exposure. Stock kits reduce service times and improve uptime.
