*568-025 FLUOROSILICONE 70 DURO ORING

Ordered as FS70025, this is an AS568-025 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring supplied with an inside diameter of 1.176 in (29.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.316 in (33.43 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Fluorosilicone (FVMQ) is specified here for very wide service temperature range and standard choice for static aerospace fuel system seals. It resists ozone and weathering, aromatic fuels and jet fuel, and chlorinated solvents. The material carries a published service range of -80°F (-62.2°C) to 350°F (176.7°C). Exposure to brake fluids or ketones will shorten service life.

Common environments for this compound include military ground vehicles, aviation fuel systems, and high-altitude equipment.

This item is sold individually under part number FS70025. Nominal inside diameter is listed as 1 3/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
