Ordered as VB75359, this is an AS568-359 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 5.725 in (145.42 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.145 in (156.08 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists aromatic hydrocarbons, many acids, and chlorinated solvents. Viton® (FKM) is valued for very low compression set at elevated temperature and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or amines are present.

Maintenance and OEM teams specify it across aerospace, oil and gas, and chemical processing.

VB75359 ships individually. Unit weight is approximately 21.425 g and nominal inside diameter is listed as 5 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
