Product Overview

Our high-performance R134a Auto Air Conditioning Hoses are engineered for maximum durability and efficiency in automotive cooling systems. Designed for cars, trucks, and engineering vehicles, these hoses are available in two specialized structures: Type C Braided (5-layer construction) and Type C Spiral (7-layer construction), ensuring superior structural integrity under extreme operational conditions.

Specially formulated to withstand the rigorous demands of modern refrigeration, our hoses offer exceptional resistance to ozone, aging, and high-pressure pulses. With a wide operating temperature range from -40°C to +135°C and full compliance with SAE J2064 and ISO/TS 16949:2009 standards, we provide a reliable solution for R12, R134a, and R404a refrigerant systems globally.
