The ac pressure hose sector is pivotal for efficient, reliable HVAC and industrial cooling operations. With a surge in demand for high-performance ac pro charging hose, ac pro hose, ac pump hose, and specialized refrigerant discharge hoses, product selection, material optimization, and compliance with standards have become top priorities. Here, we take an industry-leading look into major trends, technical parameters, manufacturing processes, and real-world applications, with a spotlight on the A10 A/C HOSE (Type C).

1. Industry Trends in AC Pressure Hose Technology

Throughout 2024, the ac pressure hose market is projected to grow at a CAGR of 4.7% (Market Insights, 2023⁽¹⁾). Major drivers include stringent ISO/ANSI compliance, development of corrosion-proof materials, and demand for hoses supporting higher refrigerant discharge pressures, especially in automotive and petrochemical sectors.

• Corrosion resistant alloys and multilayer synthetic rubbers dominate.
• Refrigerant compatibility (R134a, R1234yf, R22, etc.) is a critical selection factor.
• OEMs increasingly demand ac pressure hose solutions with longer lifecycle (30,000+ cycles) and guaranteed performance under extreme conditions (-40°C~+150°C).
