Product Description

EPDM Rubber Gasket

EPDM has excellent weather resistant characteristics. Used as higher end applications on gasketing and seals for pumps.  EPDM rubber,

commercial grade, is similar to the EPDM rubber roofing, however the commercial grade is less rigid and formable than the roofing rubber.

EPDM rubber material gasket is very resilient to alkaloids and detergents, it does have some mild resistant to petroleum. High pressure

lines and pipe gaskets use EPDM rubber because of its resistance to ultraviolet light and temperature cycling. UV and temperature

extremes cause most rubber material to become cracked brittle.

 

EPDM rubber gasket sheet is a great weather resistant material.
