This material stands up to engine and transmission fluids, many acids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in amines 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 semiconductor equipment, automotive fuel systems, and chemical processing.
V75MD041 ships individually. Nominal inside diameter is listed as 3 inch. Review your operating media and conditions against this specification before installation.
