Frequently Asked Questions
This hose is primarily designed for power steering systems and refrigeration cycles using R404a, as well as any pressure transfer assembly requiring SAE J188 compliance.
Yes, our hose is specifically engineered to be compatible with diluents, Xylene, and solvent gasoline, making it ideal for industrial equipment applications.
Working Pressure (3.5 MPa) is the maximum pressure for continuous safe operation. Burst Pressure (22.0 MPa) is the point at which the hose will fail, providing a high safety margin.
Our rubber compound is optimized for cold conditions, maintaining flexibility and softness to ensure the power steering system operates safely without cracking.
Absolutely. The material features high ozone resistance, preventing the typical dry-rot and surface cracking seen in inferior rubber products.
Yes, they are manufactured to standard inner diameters (from 7.9mm to 15.9mm) to ensure seamless integration with standard automotive and industrial clamps and fittings.
