Product Description

PRODUCT PARAMETER

EPM Washer

EPM (Ethylene Propylene Monomer) washers are rubber gaskets made from ethylene propylene rubber, known for excellent weather resistance, ozone tolerance, and heat stability (-40°C to 150°C). They resist water, weak acids, alcohols, and aging, maintaining elasticity under dynamic stress. Sizes vary to match bolts/nuts, with standards aligning with industrial sealing specs.

Applications:

Automotive: Seal door/window edges, engine bay hoses, or battery compartments (resist engine heat and weathering).
Plumbing: Gasket pipes, valves, or fittings to prevent leaks in water/fluid systems.
Electronics: Waterproof enclosures for outdoor sensors, junction boxes, or LED fixtures.
Mechanical Equipment: Dampen vibrations and seal gaps in pumps, compressors, or HVAC units.
Outdoor Infrastructure: Seal solar panel mounts, streetlight housings, or signage (withstand UV and temperature swings).

Their durability in harsh environments makes EPM washers ideal for sealing, damping, and protecting against moisture/weather in diverse industries.
