Q-430 FLUOROELASTOMER 75 Q RING

APG stocks the QV70430, an AS568-430 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 5.1 in (129.54 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.65 in (143.51 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

This material stands up to aggressive chemicals, chlorinated solvents, and petroleum oils and fuels. Viton® (FKM) delivers very low compression set at elevated temperature and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving ketones and esters or hot water and steam call for a different compound. The profile itself contributes lower compressive load required to achieve a seal and a parting line located away from the sealing surface.

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

QV70430 ships individually. Unit weight is approximately 33.964 g and nominal inside diameter is listed as 5 1/8 inch.
