3. Technical structure of air conditioning hose:
 
    For regular A/C hose has four layers, we call this A/C hose as type E air conditioner hose. Inside tube       is nylon (PA), middle layer is EPDM or IIR (Isobutylene-Isoprene Rubber), the reinforced layer is PET or     single high strengthen weaving fiber braided. Outer tube is EPDM with black and smooth cover.
    Here is another type of A/C hose with five layers. The inside tube is EPDM not PA. We call type C air         conditioner hose.
 
 
4. Production technology of air conditioning hose:
 
    When making A/C hose, mandrel process is used here. That means there will be a mandel when               making inner tube in order to make the inner diameter sizes more precise. For the cover, it is mill finish       and shining, a layer of PVC is added when making the cover, then  we will do some vulcanization for the     cover and remove the PVC layer finally. And there are some very small holes on the cover for gas             evacuation not to let the outer tube burst. All the production skill will guarantee our A/C hose to have         good performance.
 
 
5. Application of air conditioning hose:
 
   A/C hose is mainly used to convey the medium of refrigerant such as R134a, R12, R22 etc. Applied          widely to auto refrigeration in automoblie air conditioning system like bus transit system.
