-012 BROWN FKM 90D O-RING

APG stocks the VB90012, an AS568-012 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 0.364 in (9.25 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.504 in (12.8 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, the industry benchmark where nitrile reaches its thermal limit. It resists many acids, chlorinated solvents, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or ketones and esters are present.

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

VB90012 ships individually. Unit weight is approximately 0.1942 g and nominal inside diameter is listed as 3/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
