Q-452 FLUOROELASTOMER 75 Q RING

The QV70452 is an AS568-452 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 11.475 in (291.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.025 in (305.44 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) is known for outstanding high-temperature capability and very low compression set at elevated temperature. Expect good resistance to aggressive chemicals, aromatic hydrocarbons, and engine and transmission fluids. 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 a parting line located away from the sealing surface.

Maintenance and OEM teams specify it across aerospace, oil and gas, and semiconductor equipment.

Stocked as QV70452 and sold individually. Unit weight is approximately 72.47 g and nominal inside diameter is listed as 11 1/2 inch.
