In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or hot water and steam.
This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. You will find this material specified across automotive fuel systems, chemical processing, and oil and gas.
This item is sold individually under part number V75MD318. Nominal inside diameter is listed as 1 inch. Review your operating media and conditions against this specification before installation.
