O-Ring for 5/8 NRV – Viton

The Viton (FKM) O‑ring for 5/8″ NRV is a precision elastomeric sealing component designed for use in the non-return valve assemblies of foam cleaning and chemical dosing systems, where reliable sealing performance and chemical resistance are critical in food and beverage hygiene applications. Viton O‑rings provide excellent resistance to a wide range of alkaline detergents, acidic cleaners, oxidising sanitisers, and aromatic solvents, making them the preferred sealing material for chemically demanding NRV applications. Regular inspection and timely replacement of O‑rings in non-return valve assemblies are essential elements of preventive maintenance for chemical dosing systems, as seal degradation can lead to backflow events that compromise dosing accuracy and system safety.
