- Product description: Rubber EPDM O Rings
Product introduction
EPDM is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol or silicone base. This results in a highly fluorinated elastomeric compound with exceptional temperature resistance, compatibility with a wide range of aggressive chemical combinations and outstanding resistance to permanent deformation.
Chemical resistance
Hot water and steam up to 149°C with special compounds up to 260°C
Glycol based brake fluids (Dot 3 & 4) and silicone-based brake fluids (Dot 5) up to 149°C
Many organic and inorganic acids
Cleaning agents, sodium and potassium alkalis
Phosphate-ester based hydraulic fluids (HFD-R)
Silicone oil and grease
Many polar solvents (alcohols, ketones, esters)
Ozone, aging and weather resistant
