AS568-012 EPDM 70 Duro Black X-Ring

QR - Quad Rings - X-Rings

The four-lobed design of these seals provides twice the sealing surface of ordinary o-rings. They can be used in a variety of static and dynamic sealing applications including rotary, reciprocating or oscillating motion.
EPDM O-Rings:

Frequently used with foods, water, steam applications, phosphate ester type hydraulic fluids, brake fluids and offer great resistance to ozone and weathering. Sulfur-Cured FDA Grade EPDM is the least costly and provides the best tear and abrasion resistance compared to Peroxide-Cured Systems. EPDM's are not used with petroleum oils or fuels because significant swelling would result.
Chemical Resistance and Uses:

    Hot water and steam up to 300°F (149°C) with special compounds up to 400°F (204°C)
    Various Water / Municipalities Applications
    Household Appliances
    Glycol based brake fluids up to 300°F (149°C)
    Many organic and inorganic acid
    Cleaning agents, soda 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
    Outdoor Applications
    Electrical Insulators
    EPDM rubber is used in extreme cold environment applications
