Silicone O-Rings by Polypac — High-Performance Sealing Solutions

Silicone O-Rings by Polypac — engineered for reliability

Polypac's Silicone O-Rings deliver dependable sealing performance across demanding service conditions. As a scientific and technical hydraulic seal manufacturer and oil seal supplier, Polypac combines decades of materials know-how with modern production to produce silicone O-rings tailored to your operating environment — from cryogenic to high-temperature applications and from food-grade to industrial oil systems.

High-performance material properties

Silicone O-Rings offer exceptional thermal stability, low-temperature flexibility and excellent aging resistance. Polypac formulates silicone compounds to balance compression set, tear strength and chemical compatibility so seals maintain integrity in wide temperature ranges and resist degradation from common fluids, cleaners, and ozone exposure. We also provide comparative guidance on NBR, FKM, EPDM and FFKM when application requirements demand different chemical or mechanical properties.

Custom manufacturing capacity

Polypac's custom rubber ring and O-ring factory spans more than 10,000 m² with an 8,000 m² production footprint and industry-leading molding and testing equipment. We produce bespoke Silicone O-Rings in a wide range of sizes, cross-sections and tolerances, supporting rapid prototyping, small-batch runs and high-volume supply. Long-term collaborations with universities and research institutes keep our formulations and processing at the cutting edge.

Applications and compatibility

Silicone O-Rings from Polypac are ideal for hydraulic systems, medical devices, food processing equipment, instrumentation and consumer appliances where temperature extremes and elastomer longevity matter. Our technical team evaluates media compatibility (oils, fuels, refrigerants, cleaning agents) and recommends the optimal silicone grade or alternative elastomer when exposure requires higher chemical resistance.

Quality assurance and delivery

Every batch of Silicone O-Rings undergoes rigorous dimensional inspection, hardness testing and performance verification. Polypac adheres to strict quality protocols and offers traceability, material certificates and customized packaging for controlled environments. Choose Polypac for reliable sealing, timely delivery and tailored solutions backed by research-driven expertise.
