Q-225 FLUOROELASTOMER 75 Q RING

The QV70225 is an AS568-225 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 1.859 in (47.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.137 in (54.28 mm). This quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. The compound resists aromatic hydrocarbons, many acids, and chlorinated solvents. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and lower compressive load required to achieve a seal.

You will find this material specified across oil and gas, semiconductor equipment, and chemical processing.

Order part number QV70225, sold individually. Unit weight is approximately 3.047 g. Review your operating media and conditions against this specification before installation.
