Introduction to Refrigeration Hoses

Refrigeration hoses play a critical role in modern industrial and automotive systems, ensuring the safe and efficient transfer of refrigerants and other fluids. These hoses are engineered to withstand extreme conditions, including high pressure, temperature fluctuations, and exposure to corrosive substances. The Refrigeration Hose by Hebei Kemao Auto Parts Technology Co., Ltd. is a prime example of innovation in this field, combining durability, performance, and compliance with international standards.

Product Overview

The Refrigeration Hose is designed for applications requiring the transfer of refrigerants such as R404a, as well as organic solvents like diluent, xylene, and solvent gasoline. This product is specifically tailored for use in power steering systems and industrial equipment, where reliability and safety are paramount. With a working temperature range of -40℃ to +140℃, it performs exceptionally in both cold and high-temperature environments.

Constructed with a multi-layered design, the hose features a PA/NYLON barrier to prevent permeability, a EPDM/CSM/IIR friction layer for durability, and a PET/PVA reinforcement to withstand high pressure. The outer cover is made of EPDM/Cloth, providing resistance to aging, ozone, and mechanical stress.

Key Features and Advantages

The Refrigeration Hose is distinguished by its advanced features, which make it suitable for demanding environments:

• Low Permeability: The PA/NYLON barrier minimizes the risk of refrigerant leakage, ensuring efficient system performance.
• Pulse-Resistance: Designed to handle pressure fluctuations, this feature enhances the hose's longevity in dynamic systems.
• Aging-Resistance: The materials used resist degradation over time, maintaining structural integrity even after prolonged use.
• Ozone Resistance: This protects the hose from environmental factors that could lead to cracks or material breakdown.
• Shock Resistance: The construction allows the hose to endure sudden impacts, making it ideal for industrial applications.

These features align with the SAE J2064 standard, ensuring compliance with industry benchmarks for quality and safety. Additionally, the product is certified under 3C/DOT, reflecting its adherence to rigorous safety protocols.
