1. Durable EPDM rubber creates a reliable watertight seal for plumbing pumps, valves and pipe fittings.
2. Heat resistant from -50℃ to 150℃, with weather resistance, ozone resistance and chemical corrosion resistance
3. Offered wholesale in AS568, metric and JIS sizes standard; multiple colors and custom dimensions available.
Nuestro EPDM O Rings are high-performance rubber sealing components manufactured from premium ethylene propylene diene monomer (EPDM) rubber, designed for plumbing, water systems, and industrial sealing applications. These heat-resistant EPDM O-rings offer excellent resistance to hot water, saturated steam, ozone, UV radiation, weathering, and aging, making them ideal for outdoor environments and long-term sealing applications.
EPDM rubber seals also provide good compatibility with diluted acids, mild alkalis, alcohols, glycol-based brake fluids, and phosphate ester hydraulic fluids, depending on the compound formulation. Our peroxide-cured EPDM O-rings feature low compression set and reliable sealing performance under static and dynamic conditions.
Como profesional EPDM O-ring manufacturer and supplier, ofrecemos custom EPDM rubber seals, waterproof O-rings, steam-resistant O-rings, plumbing rubber seals, and industrial EPDM sealing rings in various sizes, hardness levels, and specifications to meet diverse application requirements.
