Q-113 FLUOROELASTOMER 75 Q RING

The QV70113 is an AS568-113 black Viton® (FKM) 75 Shore A Quad-Ring with an inside diameter of 0.549 in (13.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.755 in (19.18 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) is known for excellent resistance to compression set and permeation, very low compression set at elevated temperature. It resists petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with ketones and esters or low-molecular-weight organic acids. The profile itself contributes lower compressive load required to achieve a seal and two sealing bands per contact face rather than one.

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

QV70113 ships individually. Unit weight is approximately 0.564 g and nominal inside diameter is listed as 9/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
