5/16''	7.914.7	7.9±0.2	14.7±0.3	3.4	3.5	500	22.0	3000
13/32''	10.317.3	10.3±0.2	17.3±0.3	3.5	3.5	500	22.0	3000
1/2''	12.719.4	12.7±0.2	19.4±0.3	3.4	3.5	500	22.0	3000
5/8''	15.923.6	15.9±0.2	23.6±0.3	3.9	3.5	500	22.0	3000

The hose operates within a working temperature range of -40°C to +140°C (-40°F to 284°F), making it suitable for both cold and high-temperature environments. Its construction includes:

• Barrier Layer: PA/NYLON for enhanced chemical resistance.
• Friction Layer: EPDM/CSM/IIR for durability and flexibility.
• Reinforcement: PET/PVA for structural strength.
• Cover Layer: EPDM/CLOTH for protection against external elements.

These specifications ensure the hose meets the demands of diverse applications, from automotive power steering systems to industrial solvent transport.

Applications: Versatile Use in Industrial and Automotive Sectors

The Refrigeration Hose is widely used in systems requiring the safe transfer of refrigerants, solvents, and other fluids. Key applications include:

• Automotive Power Steering Systems: The hose is designed for SAE J188 standards, ensuring compatibility with power steering assemblies. It provides reliable performance in cold conditions, maintaining flexibility and pressure resistance.
• Industrial Refrigeration: Transports refrigerants like R404a and other organic solvents, such as diluents, xylene, and solvent gasoline. Its low permeability minimizes environmental impact.
• Chemical Processing: Suitable for conveying aggressive solvents due to its ozone and aging resistance, making it ideal for industrial equipment.

As noted by the National Institute of Standards and Technology (NIST), "Precision in material specifications is critical for ensuring safety and efficiency in fluid transport systems" (NIST, 2025). The Refrigeration Hose aligns with these principles, offering a solution that balances performance with compliance.
