Durable, flexible, and highly resistant to pressure, temperature, and corrosion, ensuring reliable performance in automotive A/C systems. Best quality.
Our automotive air-conditioning (A/C) lines are engineered specifically for refrigerant transfer (R134a / R1234yf / CO₂) in vehicle climate-control systems.
With 20+ years of manufacturing expertise, we ensure robust sealing performance, exceptional corrosion resistance, customized routing, OE-grade reliability, and long service life for OEM and aftermarket vehicles.
A/C pipelines are manufactured using multi-layer aluminum tubing, rubber hoses, or stainless-steel reinforcement to ensure high performance under extreme temperature cycling and vibration environments.
High-pressure performance
Designed to withstand refrigerant pressure fluctuations to ensure stable cooling efficiency and leak-free operation.
Superior refrigerant containment
Uses multi-layer hose materials with low-permeation properties; meets SAE J2064 requirements for refrigerant retention.
Excellent corrosion resistance
Aluminum or stainless-steel tubing with anti-corrosion coatings provides long-term durability.
Durable connector ends
Precision-engineered fittings support quick installation, high sealing reliability, and resistance to vibration fatigue.
Custom thermal & routing designs
Compatible with tight engine bay conditions; options include rubber-aluminum hybrid structures & noise-reduction sleeves.
Leak-proof performance
Precise dimensional control and surface treatment ensure long-term refrigerant sealing—critical for cooling efficiency and passenger comfort.
