- Commodity name： Heavy Duty CH Series Air Conditioning Hose SAE J2064 Bus Truck JUNZE
- Description
-
A bus or truck AC system runs longer lines, harsher vibration, and harder service schedules than a passenger car. The CH series answers with the thickest walls in the JUNZE AC range — 6.2mm on the 10mm bore — sized for the sustained duty of commercial vehicle air conditioning.
The heavy wall adds abrasion and impact margin for exposed chassis runs on trucks, bus floors, and reefer installations, while the certified construction keeps R134a and R1234yf compatibility across -40°C to +135°C. Working pressure is rated at 3.5MPa with 15MPa minimum burst.
