This o-ring is supplied in AS568-328 brown Viton® (FKM) 75 Shore A built to an inside diameter of 1.85 in (46.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.27 in (57.66 mm), catalogued under part number VB75328. It remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Expect good resistance to aggressive chemicals, aromatic hydrocarbons, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life.
Maintenance and OEM teams specify it across automotive fuel systems, oil and gas, and semiconductor equipment.
This item is sold individually under part number VB75328. Unit weight is approximately 7.8583 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
