NSF-compliant EPDM (Ethylene Propylene Diene Monomer) O-rings are made from a synthetic elastomer that provides outstanding resistance to water, steam, and cleaning chemicals. These compounds are certified to meet NSF/ANSI Standard 61 requirements for use in drinking water and potable water system components. NSF EPDM O-rings maintain long-term sealing integrity in environments where safety, hygiene, and water purity are critical.

NSF-Compliant EPDM O-Ring Recommended Uses

Potable water systems, plumbing fixtures, filtration equipment, beverage dispensing systems, water treatment facilities, and sanitary processing equipment.

NSF-Compliant EPDM O-Ring Not Recommended

Oils, fuels, aromatic hydrocarbons, and solvents that may cause EPDM to swell or degrade.

NSF-Compliant EPDM O-Ring Limitations

Not compatible with petroleum-based oils and fuels.
Limited resistance to non-polar solvents and hydrocarbons.
Not ideal for applications requiring very low-temperature flexibility.
Not recommended for use in dynamic sealing under high pressure.

NSF-Compliant EPDM O-Ring Usable Temperature Range

-50 to 300°F (-46 to 149°C)

NSF-Compliant EPDM O-Ring Also Known As

NSF EPDM, EPDM Rubber (NSF 61 Compliant), Ethylene Propylene Rubber, Potable Water EPDM O-Ring.
