*4170-514AD MINNESOTA RUBBER QUAD RING

APG stocks the VQ4170, an AS568-170 black Viton® (FKM) 75 Shore A quad profile Quad-Ring supplied with an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The material holds up against petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound.

Common environments for this compound include high-temperature process equipment, aerospace, and semiconductor equipment.
