Expect good resistance to many acids, chlorinated solvents, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for very low compression set at elevated temperature and outstanding high-temperature capability. It is not the right choice where amines or ketones and esters are present.

This item is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across oil and gas, aerospace, and automotive fuel systems.

Stocked as 0283MD139 and sold by the foot. Application requirements vary, so validate compatibility with your process conditions prior to installation.
