Q-216 FLUOROELASTOMER 75 Q RING

Ordered as QV70216, this is an AS568-216 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 1.109 in (28.17 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.387 in (35.23 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) is specified for outstanding high-temperature capability, excellent resistance to compression set and permeation. The material holds up against petroleum oils and fuels, 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 lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

Typical settings include chemical processing, oil and gas, and high-temperature process equipment.

QV70216 ships individually. Unit weight is approximately 1.805 g and nominal inside diameter is listed as 1 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
