Q-202 FLUOROELASTOMER 75 Q RING

Ordered as QV70202, this is an AS568-202 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 0.234 in (5.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.512 in (13 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

It resists aggressive chemicals, petroleum oils and fuels, and aromatic hydrocarbons. Viton® (FKM) offers very low compression set at elevated temperature, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids. The profile itself contributes resistance to the spiral twisting that defeats round-section rings and two sealing bands per contact face rather than one.

It sees regular use in chemical processing, semiconductor equipment, and oil and gas.

Order part number QV70202, sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
