Product Overview
The AC rubber hose is a critical component engineered for high-performance air conditioning systems in automotive, commercial, and industrial applications. Designed to transport refrigerants such as R134a and R1234yf under extreme pressures and temperatures, our AC rubber hose ensures seamless operation and longevity. Crafted from premium synthetic rubber compounds reinforced with multiple layers of textile braids and steel wire spirals, this hose withstands pulsations, vibrations, and environmental stresses common in demanding environments.
Available in various diameters and lengths, our AC rubber hose meets international standards like SAE J2064, ISO 10619, and SAE J51, guaranteeing compatibility and safety. Whether you're equipping vehicles, refrigeration units, or HVAC systems, this hose delivers exceptional flexibility without compromising on durability. Its inner tube is formulated to resist permeation and degradation, while the outer cover provides superior ozone, UV, and abrasion resistance, making it ideal for global markets where reliability is paramount.
With a focus on precision manufacturing, each AC rubber hose undergoes rigorous testing for burst pressure, impulse cycles, and vacuum performance, ensuring it exceeds industry benchmarks. This product is not just a conduit for refrigerant; it's a dependable partner in maintaining optimal cooling efficiency and system integrity.
Key Features
- Multi-Layer Reinforcement: High-tensile textile braids combined with steel wire helix for superior pressure resistance up to 600 psi working pressure and burst pressures exceeding 2400 psi.
- Advanced Rubber Compounds: EPDM or chloroprene inner liner resistant to refrigerants, oils, and chemicals, paired with a CSM or CR outer cover for exceptional weather and aging resistance.
- Temperature Resilience: Operates reliably from -40°C to +125°C, accommodating the thermal cycles of AC systems without hardening or cracking.
- Low Permeation Design: Meets stringent SAE J2064 Type A/B permeability requirements, minimizing refrigerant loss and environmental impact.
- Flexible and Lightweight: Bend radius as low as 4x ID, reducing installation stress and enhancing routing in tight spaces.
- Custom Fitting Compatibility: Ends crimped or swaged with O-ring face seal, JIC, or quick-connect fittings for easy integration.
- Color-Coded Identification: Distinctive orange or blue outer layers for quick visual recognition in assembly lines.
These features make our AC rubber hose the go-to solution for manufacturers seeking performance without compromise.

Application Scenarios
Our AC rubber hose excels in a wide array of scenarios where efficient refrigerant flow is essential. In the automotive sector, it's widely used in passenger cars, trucks, buses, and heavy machinery AC systems to connect compressors, condensers, evaporators, and accumulators. Its flexibility allows for compact engine bay installations, enduring constant vibrations and heat from exhaust proximity.
In commercial refrigeration, the AC rubber hose supports walk-in coolers, display cases, and transport units, handling low-temperature operations without brittleness. Industrial HVAC applications benefit from its high-pressure capability in chillers and heat pumps for large-scale buildings. Additionally, it's deployed in off-road vehicles, agricultural equipment, and marine AC systems, where exposure to moisture, salt, and dirt demands robust protection.
For aftermarket repairs and OEM production, pre-assembled AC rubber hose assemblies reduce downtime and ensure leak-free performance, making it indispensable for global supply chains.
Advantages
Choosing our AC rubber hose provides distinct advantages over standard alternatives. Its superior impulse resistance—surviving over 150,000 cycles—translates to fewer failures and extended service life up to 15 years in typical conditions. Low permeation rates comply with global environmental regulations like the EU F-Gas Directive, reducing refrigerant recharge frequency and operational costs.
The hose's lightweight construction lowers vehicle fuel consumption, while its abrasion-resistant cover minimizes wear in under-hood environments. Manufacturing precision ensures consistent ID tolerances, preventing flow restrictions and pressure drops. Backed by third-party certifications (UL, CCC, ECE), it offers peace of mind for exporters and importers alike.
Compared to thermoplastic hoses, our rubber-based AC rubber hose provides better collapse resistance under vacuum, ideal for evaporator suction lines. Bulk packaging options optimize logistics, supporting just-in-time delivery for high-volume B2B orders.
