AS568-021 FDA EPDM 70 Duro Black X-Ring

15/16"ID X 1 1/16"OD X 1/16"CS

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
