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
