568-214 FLUOROSILICONE 70 DURO ORINGS

Part number FS70214 is an AS568-214 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring with an inside diameter of 0.984 in (24.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.262 in (32.05 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Fluorosilicone (FVMQ) delivers excellent ozone and UV stability, silicone's low-temperature flexibility combined with fuel resistance. The compound resists ozone and weathering, extreme cold, and aromatic fuels and jet fuel. Service temperature is rated from -80°F (-62.2°C) through 350°F (176.7°C). It is not the right choice where hydrazine or brake fluids are present.

Maintenance and OEM teams specify it across high-altitude equipment, aerospace and defense, and aviation fuel systems.

Stocked as FS70214 and sold individually. Unit weight is approximately 1.3826 g and nominal inside diameter is listed as 1 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.
