The V4X56 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 56 mm (2.205 in), a cross section of 4 mm (0.157 in), and an outside diameter of 64 mm (2.52 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. It resists aggressive chemicals, chlorinated solvents, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or ketones and esters will shorten service life.
Maintenance and OEM teams specify it across high-temperature process equipment, oil and gas, and semiconductor equipment.
This item is sold individually under part number V4X56. Unit weight is approximately 4.3287 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
