Is the Polyester reinforced silicone hose, ML, blue suitable for use with engine oils and fuel, or should I choose the fluorosilicone inner layer version?

The Polyester reinforced silicone hose, ML, 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 significant oil mist exposure you should choose the version with a fluorosilicone inner layer. In short: use Polyester reinforced silicone hose, ML, blue for coolant/air applications and minor oil mist only; for engine oils and fuels, select the fluorosiliconeâlined version.

Can the Polyester reinforced silicone hose, ML, blue be used for prolonged exposure to coolant mixed with oil mist without the fluorosilicone inner layer?

No-use of the Polyester reinforced silicone hose, ML, blue for prolonged exposure to coolant mixed with oil mist is not recommended without the fluorosilicone inner layer. The product description specifies the standard silicone version is intended for water, coolant fluids, and air with only a small amount of oil mist; for oils, fuels, and oil mist a fluorosilicone inner layer is recommended to ensure chemical compatibility and long-term resistance. For prolonged exposure to oil-contaminated coolant, choose the fluorosilicone-lined variant.

Does the Polyester reinforced silicone hose, ML, blue meet SAE J20R1 standards for automotive coolant systems?

Yes. Polyester reinforced silicone hose, ML, blue meets SAE J20R1 standards for automotive coolant systems. The product description explicitly states that the hose meets SAE J20R1, is intended for cooling and heating systems in vehicles, and has suitable working pressures (0.86â8.75 bar depending on diameter), a 3:1 pressure safety factor, and an operating temperature range of â50Â°C to +180Â°Câproperties consistent with SAE J20R1 requirements for coolant hoses.
