Ampco N70373 Buna-N O-Ring
This o-ring is a Buna-N replacement part for Ampco Pumps sanitary and industrial pump equipment. Ampco builds its AC/AC+, IC+, CB+, and ZP series pumps for food, beverage, dairy, and pharmaceutical processing, and static seals like this one keep product contained at the casing, cover, and shaft joints.
Elastomer compatibility matters as much as fit: the material is selected to match your process fluid, temperature, and cleaning chemicals, so order the same material code as the part you're replacing unless a chemical compatibility review calls for a change.
