NSF certified EPDM o-rings are a type of sealing device that are made of Ethylene Propylene Diene Monomer (EPDM), a synthetic rubber that is known for its excellent resistance to heat, ozone, and weathering. The o-rings are certified by NSF (National Sanitation Foundation), an independent organization that evaluates and certifies products for use in the food and beverage industry. These o-rings are ideal for use in applications where exposure to food or potable water is a concern, such as in food processing and bottling equipment, and water filtration systems. The certification guarantees that the EPDM o-rings are manufactured to meet strict standards for material safety and cleanliness, and that they are safe for use in contact with food and potable water.
