*4147-514AD MINNESOTA RUBBER QUAD RING

Part number VQ4147 is an AS568-147 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 2.675 in (67.95 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.881 in (73.18 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

The material holds up against petroleum oils and fuels, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit 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 amines or ketones and esters are present.

Maintenance and OEM teams specify it across automotive fuel systems, aerospace, and semiconductor equipment.
