Q-207 FLUOROELASTOMER 75 Q RING

The QV70207 is an AS568-207 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 0.546 in (13.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.824 in (20.93 mm). This quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

This material stands up to chlorinated solvents, many acids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where ketones and esters or amines are present. The profile itself contributes two sealing bands per contact face rather than one and lower compressive load required to achieve a seal.

It sees regular use in semiconductor equipment, high-temperature process equipment, and oil and gas.
