5.7MM CS X 154.3MM ID BLACK FKM 75D

Ordered as V5.7X154.3, this is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 154.3 mm (6.075 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 165.7 mm (6.52 in). The 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 G155.

As a material, Viton® (FKM) is specified for excellent resistance to compression set and permeation, very low compression set at elevated temperature. The material holds up against aromatic hydrocarbons, engine and transmission fluids, and petroleum oils and fuels. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.

Maintenance and OEM teams specify it across automotive fuel systems, high-temperature process equipment, and semiconductor equipment.
