Production technology of air conditioning hose:
 

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

When making Air conditioning 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.

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 air conditioning hose to have good performance.
