Product Specification

-
Part number V90318 is an AS568-318 black Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 0.975 in (24.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.395 in (35.43 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Viton® (FKM) offers excellent resistance to compression set and permeation, very low compression set at elevated temperature. It resists aggressive chemicals, many acids, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

You will find this material specified across automotive fuel systems, aerospace, and chemical processing.

Reference part number V90318 when ordering; the item is sold individually. Unit weight is approximately 3.8229 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
