4MM CS X 52MM ID BLACK FKM 75D

The V4X52 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 52 mm (2.047 in), a cross section of 4 mm (0.157 in), and an outside diameter of 60 mm (2.36 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) is specified here for industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. This material stands up to chlorinated solvents, aggressive chemicals, and engine and transmission fluids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound.

Maintenance and OEM teams specify it across oil and gas, semiconductor equipment, and aerospace.

Order part number V4X52, sold individually. Unit weight is approximately 4.0824 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
