Viton® (FKM) is valued for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. This material stands up to chlorinated solvents, many acids, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound.
Typical settings include oil and gas, automotive fuel systems, and aerospace.
SB-V70121-50 ships by the bag. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
