Our Large Size Rubber O-Ring Seals are specifically engineered for industrial and heavy-duty machinery that demand high-performance sealing solutions. Designed to handle wide sealing surfaces and high mechanical loads, these large diameter O-rings provide excellent compression resistance, long service life, and stable sealing even under harsh working conditions.

Manufactured using advanced molding and splicing technology, they ensure smooth joints, consistent cross-sectional profiles, and reliable elasticity. Available in materials such as NBR (Nitrile), EPDM, FKM (Viton), and Silicone, each chosen based on chemical compatibility, temperature resistance, and environmental exposure.

These large O-rings are commonly used in pumps, turbines, pipelines, pressure vessels, flanges, and large hydraulic systems. They can withstand extreme temperatures, pressure variations, and contact with oils or chemicals.

Custom sizes up to several meters in diameter can be produced according to international standards such as AS568, BS, and ISO 3601. We also provide OEM service with options for hardness (50–90 Shore A), color customization, and surface treatments.
