Is the Silicone 45Â° polyester-reinforced elbow, E45, blue suitable for use with engine oil and fuel, or is the fluorosilicone-lined version required?

Silicone 45Â° polyester-reinforced elbow, E45, blue is intended for cooling and heating systems in vehicles (water, coolant fluids, clean air or air with a small amount of oil mist). For oils, fuels, and oil mist, the fluorosilicone-lined version is recommended. Therefore, the standard Silicone 45Â° polyester-reinforced elbow, E45, blue is not suitable for use with engine oil and fuel; use the fluorosilicone-lined version for those applications.

Can the Silicone 45Â° polyester-reinforced elbow, E45, blue withstand continuous exposure to coolant fluids and mild oil mist in vehicle HVAC systems?

Yes. Silicone 45Â° polyester-reinforced elbow, E45, blue is designed for vehicle cooling and heating systems and is suitable for continuous exposure to coolant fluids and clean air or air with a small amount of oil mist. For heavier oil exposure (oils, fuels, significant oil mist) a version with a fluorosilicone inner layer is recommended. Operating range: -50Â°C to +180Â°C, working pressure from 1.5 to 8.33 bar (depending on diameter), pressure safety factor 3:1; meets SAE J20R1.

What is the maximum working pressure for the Silicone 45Â° polyester-reinforced elbow, E45, blue across available diameters?

Silicone 45Â° polyester-reinforced elbow, E45, blue. maximum working pressure across available diameters is 8.33 bar. The productâs working pressure range is from 1.5 bar up to a maximum of 8.33 bar, varying by hose diameter (pressure safety factor 3:1).
