The o-ring delivers dependable bidirectional sealing in a compact groove envelope. This item is further identified as Metric O-RING, JIS P355.
Viton® (FKM) is specified here for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. It resists engine and transmission fluids, aggressive chemicals, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.
It sees regular use in semiconductor equipment, chemical processing, and aerospace.
