EPDM O-Rings 1.78 CS (mm) Dia ID 26 to 50 (mm)

Material: EPDM Rubber , Hardness : 70 Duro

Colour: Black, Shelf Life: 5 years, 

EPDM O-Rings:

Normally 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
