Can Silicone 90Â° polyester-reinforced elbow, E90, blue be used with oil mist or should I choose the fluorosilicone inner layer version?

Silicone 90Â° polyester-reinforced elbow, E90, blue is intended for cooling and heating systems in vehicles and for conveying water, coolant fluids and clean air or air with a small amount of oil mist. For applications involving oils, fuels or significant oil mist, you should choose the version with a fluorosilicone inner layer. In short: for only a small amount of oil mist the standard Silicone 90Â° polyester-reinforced elbow, E90, blue may be acceptable; for oils, fuels or persistent/heavy oil mist use the fluorosiliconeâlined version.

Can the Silicone 90Â° polyester-reinforced elbow, E90, blue handle pressures up to 8.75 bar across all diameters?

No - Silicone 90Â° polyester-reinforced elbow, E90, blue handle cannot sustain 8.75 bar across all diameters. The working pressure ranges from 1.83 bar up to 8.75 bar depending on hose diameter, so only the smallest/approved diameters reach the maximum 8.75 bar; others have lower working pressures. Pressure safety factor is 3:1.

Q: Is the Silicone 90Â° polyester-reinforced elbow, E90, blue compatible with fuels?

No. Silicone 90Â° polyester-reinforced elbow, E90, blue is intended for cooling and heating systems (water, coolant fluids, clean air or air with a small amount of oil mist). For oils, fuels, and oil mist a version with a fluorosilicone inner layer is recommended, so the standard polyester-reinforced E90 (blue) is not suitable for use with fuels.
