Is the Polyester-reinforced silicone 90Â° reduction elbow, ER, blue suitable for oil, fuel, or oil-mist applications, and is a fluorosilicone inner layer available?

The Polyester-reinforced silicone 90Â° reduction elbow, ER, blue is intended for cooling and heating systems in vehicles . suitable for water, coolant fluids, and clean air or air with a small amount of oil mist. For oils, fuels, and oil-mist applications a version with a fluorosilicone inner layer is recommended and available. Thus, the standard polyester-reinforced blue version is not recommended for oils, fuels, or heavy oil-mist exposure; choose the fluorosiliconeâlined variant for those media.

Can the Polyester-reinforced silicone 90Â° reduction elbow, ER, blue withstand continuous use at +180Â°C and repeated thermal cycling?

Yes. The Polyester-reinforced silicone 90Â° reduction elbow, ER, blue is rated for an operating temperature range of -50Â°C to +180Â°C, so it can withstand continuous use at +180Â°C. It is designed for vehicle cooling and heating systems and meets SAE J20R1 standards; polyester reinforcement and ~65Â° Shore A hardness support durability. However, for repeated thermal cycling note that polyester-reinforced silicone performs well within the specified range but longevity depends on cycle severity, pressure, fluid compatibility and installation stress. For oils, fuels or oil mist use the fluorosilicone-inner version. If your application involves extreme cycling, continuous high pressure near the upper working pressure, or aggressive fluids, validate with manufacturer testing or select a version specifically rated for your duty cycle.

What are the recommended pressure limits and safety factor for the Polyester-reinforced silicone 90Â° reduction elbow, ER, blue?

The Polyester-reinforced silicone 90Â° reduction elbow, ER, blue has a working pressure range from 1 bar to 7.33 bar (depending on hose diameter) and a pressure safety factor of 3:1. Operating temperature range: -50Â°C to +180Â°C. Standard hardness â65Â° Shore A; density â1.26 g/cmÂ³. Meets SAE J20R1. For oils, fuels or significant oil mist use the fluorosiliconeâlined version. Standard arm length: 102 mm.
