1" Tri Clamp Gasket FDA NSF61 EPDM 70 Duro - Peroxide Cured

Tri-Clamp gaskets are used to make a secure, leak-proof connection between clamp fittings.

FDA/NSF Compliant 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. Peroxide Cured EPDM FDA/NSF-61 are Chloramine Resistant and stronger and have better chemical and chloramine resistance than sulfur cured compounds. 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

EPDM is not recommended for:

• Mineral oil products (oils, greases and fuels)
• Solvents
