ORings Key benefits Provide a simple, reliable seal for static and dynamic connections to prevent leaks of liquids and gases. Easy to install and , reducing downtime and maintenance cost. Compatible with many systems when the correct material and size are selected, making them a versatile sealing solution. What they do Create a compressible barrier in a groove between two mating parts to stop fluid or gas passage. Work in static seals (flanges, pipe joints) and many dynamic seals (pistons, shafts) when matched to application conditions. Important attributes Function: sealing for pressure containment and leak prevention in mechanical assemblies. Compatibility: choose Oring material based on chemical exposure and temperature. Common materials include NBR (nitrile) for oils and fuels, FKM/Viton for higher heat and chemical resistance, EPDM for water and steam, and silicone for wide temperature range. Confirm compatibility for your specific fluid. Size: available in standard crosssections and inner diameters to fit common grooves and housings. Select the correct inner diameter and crosssection to ensure proper squeeze and compression. Material & performance: performance depends on material choice. Proper selection balances temperature range, chemical resistance, hardness (durometer), and wear resistance for the intended pressure and motion. Practical applications Hydraulic and pneumatic cylinders: seal pistons and rods to prevent fluid loss under pressure. Plumbing and HVAC: or assemble valves, fittings, and pumps to stop leaks in water, refrigerant, or coolant lines. Automotive and industrial machinery: seal oil pans, fuel systems, and gearboxes where reliable containment is required. Installation and maintenance tips Inspect groove and mating surfaces for scratches or debris before fitting. Use correct lubrication compatible with the Oring material to ease installation and reduce wear. Orings during scheduled maintenance or at first sign of hardening, cracking, or extrusion. Select the right Oring material and size for your system to ensure reliable sealing and long service life.
