EPDM O-Ring 55x2 mm

Overview

The EPDM O-Ring 55x2 mm is a high-quality sealing element manufactured from EPDM (Ethylene Propylene Diene Monomer) rubber, designed for static and low-speed dynamic sealing applications. EPDM offers outstanding resistance to hot water, steam, ozone, UV radiation and weathering, making it an excellent choice for hydraulic, sanitary and industrial systems operating under demanding environmental conditions. The material maintains excellent elasticity and sealing performance over a wide temperature range.

Industrial Applications

The 55x2 mm EPDM O-Ring is widely used in drinking water systems, sanitary installations, heating systems, cooling circuits, pneumatic equipment, food processing machinery, beverage production, irrigation systems, water treatment plants, valves, pumps, heat exchangers and OEM industrial equipment.

Construction

The O-ring features a precision-moulded 2 mm cross-section and a 55 mm inside diameter, ensuring uniform sealing pressure within standard gland designs. Its circular profile provides reliable sealing performance while minimizing leakage and maintaining long service life under static and moderate dynamic operating conditions.

Material

The seal is manufactured from EPDM synthetic rubber, typically with a hardness of 70 Shore A. EPDM provides excellent resistance to hot water, steam, glycol-based fluids, brake fluids, ozone, UV radiation and ageing. The material typically operates within a temperature range of approximately -40°C to +120°C, with certain compounds suitable for even higher temperatures. EPDM is not recommended for use with mineral oils, fuels or petroleum-based lubricants.
