GlobalSeals has over twenty-five years experience specializing in the manufacturing of precision molded EPDM rubber gaskets and seals for a wide range of industries and applications. 

EPDM is an Excellent General purpose rubber and relatively inexpensive material.  Excellent resistance to heat, cold, ozone, and ultraviolet light. Also has excellent chemical resistance and excellent electrical and dynamic properties.  EPDM rubber gaskets provide reliable, long-term sealing in extreme weather conditions and over a wide range of temperatures,this makes an excellent material for outdoor applications. 

It is often used in drinking water systems (NSF, KTW, W270,WRAS) due to its Chlorine and Chloramine resistance and in hydraulic and braking systems due to its excellent Glycol resistance. EPDM is available in o-rings, gaskets, custom molded products or others. 

EPDM gaskets can be cured with either Sulphur or Peroxide. Sulphur curing is less expensive and easier to process but the product may be tacky and can exhibit some bloom. Peroxide curing is more difficult to process but provides better chemical, thermal, and aging resistance.

EPDM rubber is also color-stable, which means that EPDM gaskets won’t stain mating surfaces. EPDM gaskets also provides good electrical insulation; however, custom gaskets made of EPDM rubber are not recommended for contact with most oils, gasoline, halogenated solvents, and concentrated acids.
