NSF 61 Certified Materials
The National Sanitation Foundation is the certifying authority for the US Standard NSF/ANSI 61 which specifies the degree of contaminants and impurities allowable that may pass on into drinking water systems during the stages treatment and distribution throughout the water supply network. O-rings and seals used in potable water systems must meet the Standard of NSF 61 in order to ensure that toxicity and contaminants are not introduced into drinking water supply systems.
NSF 61 certification level makes a distinction between certification for just potable water, or the more stringent certification for chemicals that are used in the potable water production process. Chemical certification pertains to specific chemicals at specific levels of concentration.
Gmors maintains an complete inventory of of NSF 61 certified o-rings, seals and gaskets in various material grades and we also meet custom designed requirements.
Peroxide Cured vs Sulfur Cured EPDM Seals and Gaskets
EPDM is highly versatile and is one of the most extensively used rubber compounds. It is classified as an M-Class synthetic rubber and is characterized by its excellent resistance to weathering exposure, heat and ozone degradation. Additionally, EPDM is compatible with hot and cold water, steam, ketones as well as non-concentrated acids and alkalis.
The application and service environment of EPDM o-rings, seals and gaskets will determine the method of curing of the compound. Each curing method will result in different physical and mechanical properties in the final product, and understanding our specific service conditions is important in our choice of a compatible EPDM compound.
