The V5.7X69.6 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 69.6 mm (2.74 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 81 mm (3.19 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. Supplementary detail from the product record: Metric O-RING, JIS P70.

Viton® (FKM) is specified here for outstanding high-temperature capability and industry benchmark where nitrile reaches its thermal limit. Expect good resistance to many acids, aromatic hydrocarbons, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

It sees regular use in high-temperature process equipment, chemical processing, and oil and gas.
