Product Specification

-
The V3.5X31 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 31 mm (1.22 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 38 mm (1.5 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The compound resists chlorinated solvents, aggressive chemicals, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with hot water and steam or ketones and esters.

You will find this material specified across aerospace, high-temperature process equipment, and chemical processing.

V3.5X31 ships individually. Unit weight is approximately 1.9276 g. Check the compound against your process media, pressure and temperature before committing to a design.
