Q-170 FLUOROELASTOMER 75 Q RING

Ordered as QV70170, this is an AS568-170 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). The quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. The compound resists petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with ketones and esters or amines. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

Common environments for this compound include semiconductor equipment, automotive fuel systems, and high-temperature process equipment.

This item is sold individually under part number QV70170. Unit weight is approximately 6.523 g and nominal inside diameter is listed as 7 3/4 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.
