Q-211 FLUOROELASTOMER 75 Q RING

Ordered as QV70211, this is an AS568-211 black Viton® (FKM) 75 Shore A Quad-Ring built to an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

As a material, Viton® (FKM) is specified for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. This material stands up to aggressive chemicals, petroleum oils and fuels, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). The profile itself contributes lower compressive load required to achieve a seal and resistance to the spiral twisting that defeats round-section rings.

Maintenance and OEM teams specify it across automotive fuel systems, oil and gas, and semiconductor equipment.

QV70211 ships individually. Unit weight is approximately 1.4918 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
