1.5MM CS X 18MM ID BLACK FKM 75D

The V1.5X18 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 18 mm (0.709 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 21 mm (0.83 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against aggressive chemicals, chlorinated solvents, and many acids. Viton® (FKM) is specified for excellent resistance to compression set and permeation, very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present.

Typical settings include automotive fuel systems, semiconductor equipment, and high-temperature process equipment.

Stocked as V1.5X18 and sold individually. Unit weight is approximately 0.1975 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
