Q-334 FLUOROELASTOMER 75 Q RING

APG stocks the QV70334, an AS568-334 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The compound resists engine and transmission fluids, aromatic hydrocarbons, and petroleum oils and fuels. Viton® (FKM) delivers outstanding high-temperature capability and very low compression set at elevated temperature. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). The profile itself contributes two sealing bands per contact face rather than one and resistance to the spiral twisting that defeats round-section rings.

It sees regular use in oil and gas, high-temperature process equipment, and semiconductor equipment.

Reference part number QV70334 when ordering; the item is sold individually. Unit weight is approximately 9.952 g and nominal inside diameter is listed as 2 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
