5MM CS X 53MM ID BLACK FKM 75D

The V5X53 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 53 mm (2.087 in), a cross section of 5 mm (0.197 in), and an outside diameter of 63 mm (2.48 in). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists petroleum oils and fuels, many acids, and aromatic hydrocarbons. That behavior comes from the compound itself: 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). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

Typical settings include oil and gas, aerospace, and high-temperature process equipment.

Order part number V5X53, sold individually. Unit weight is approximately 6.5585 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
