Sterling Seal & Supply (STCC) EPDM NSF-61, size -450 70D O-Ring

Millions of people take the safety of their food, water and consumer products for granted on a daily basis Why? Because of three letters: NSF NSF certification is your key to making sure that the products you use meet strict standards for public health protection; Sterling Seal & Supply EPDM 70 durometer NSF approved O-rings are your answer In the rubber industry, the most important standard by far, is the NSF Standard 61 Rubber compounds submitted to NSF undergo rigorous testing to determine whether any contaminants leach or migrate from the material when in long term contact with drinking water, and if so, if the level of migration is acceptable from a public health viewpoint These compounds also comply with FDA requirements EPDM O-rings provide resistance to heat, water and steam, alkali, mild acidic oxygenated solvents, ozone and UV exposure EPDM O-ring compounds also withstand the effect of brake fluids and Skydrol, and other hydraulic fluids EPDM compounds are not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments NSF/ANSI Standard 61 is an US Standard issued by the National Sanitation Foundation which defines the acceptable levels of contaminating substances and impurities that may leach or migrate from components and devices into drinking water systems Whether you manufacture valves, faucets, copper tubing, sinks, thermostatic mixing valves, backflow preventers, toilets, septic tanks, showers or practically any other type of plumbing product, NSF provides the testing and certifications you need to gain product acceptance and code compliance across North America Faucets and plumbing products intended for contact with drinking water should be tested and certified to NSF/ANSI Standard 61 This American National Standard limits the amount of impurities that individual products can introduce into a home’s water supply, including lead and other metals, volatile organic chemicals, phthalates and bisphenol A
