O-ring EPDM

EPDM (ethylene-propylene-diene rubber) is a synthetic rubber elastomer that can be crosslinked with sulfur or cured with peroxide. O-rings are the most common type of seal, they are cheap and simple, and can be used everywhere in hydraulic and pneumatic systems. Under appropriate working conditions and with the right equipment, they can be used both statically and dynamically, but O-rings are not recommended for rotating movements. Compared to other sealing elements, component development is made easier with the use of O-rings, as they take up less space and have a double-acting seal. Relevant precautions must be taken, the right materials chosen, and a suitable surface quality on metal parts maintained for a good result with O-rings. PRODUCT BENEFITS • Can be used both statically and dynamically • Suitable for both piston rods and pistons • Several different compounds • Several different dimensions • Easy to install and remove • Very good resistance to heat, water, ozone, ageing, and weathering • Good resistance to steam and polar substances APPLICATION Used in almost all industries, especially in stationary machines and with static sealing, for example as flange or cover gaskets. EPDM O-rings are known for being suitable for hot water and brake fluids (based on glycol). EPDM O-rings should not be used with mineral oil, fats, and fuels. EPDM has excellent insulating properties against electricity. Good mechanical properties and good resistance to ozone, ageing, and weathering.
