568-270 FLUOROSILICONE 70 DURO ORING

Ordered as FS70270, this is an AS568-270 blue Fluorosilicone (FVMQ) 70 Shore A O-Ring built to an inside diameter of 8.984 in (228.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.262 in (235.25 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against ozone and weathering, aromatic fuels and jet fuel, and petroleum oils. That behavior comes from the compound itself: Fluorosilicone (FVMQ) offers the standard choice for static aerospace fuel system seals and silicone's low-temperature flexibility combined with fuel resistance. Rated temperature range runs from -80°F (-62.2°C) to 350°F (176.7°C) in continuous service. Applications involving high-temperature dynamic service or brake fluids call for a different compound.

Typical settings include aerospace and defense, high-altitude equipment, and military ground vehicles.

This item is sold individually under part number FS70270. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
