*4267-514AD MINNESOTA RUBBER QUAD RING

The VQ4267 is an AS568-267 black Viton® (FKM) 75 Shore A quad profile Quad-Ring measuring an inside diameter of 8.234 in (209.14 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.512 in (216.2 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Viton® (FKM) offers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material holds up against engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound.

You will find this material specified across semiconductor equipment, high-temperature process equipment, and chemical processing.

VQ4267 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
