The VB75M1.5X15.5 is a brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 15.5 mm (0.61 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 18.5 mm (0.73 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope. Source specification: Metric O-RING, JIS S16.
It resists petroleum oils and fuels, many acids, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or hot water and steam.
You will find this material specified across automotive fuel systems, high-temperature process equipment, and aerospace.
This item is sold individually under part number VB75M1.5X15.5. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
