The compound resists aggressive chemicals, petroleum oils and fuels, and many acids. Viton® (FKM) is known for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).
The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across high-temperature process equipment, semiconductor equipment, and chemical processing.
This item is sold individually under part number V75MD044. Nominal inside diameter is listed as 3 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
