Flexible Rubber Refrigerant Line Air Conditioning Hose 500psi For Bus System

Bus Air Conditioning System Flexible Rubber Refrigerant Line Hose 500psi

Part Type:  Air Conditioning Hoses and Lines
Air standard refrigeration line feature barrier-type refrigerant line for use with134a, R-12 or R410a refrigerants.
 

 

2. Sizes and performace parameters of air conditioning hose:

Production technology:
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.
 
 
Application of air conditioning hose:
 
A/C hose is mainly used to convey the medium of refrigerant such as R134a, R12, R22, R410a etc.
Applied widely to auto refrigeration in automoblie air conditioning system like bus transit system. 
 
 
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. 
 

We can also producing air conditioning hose assembly as following pictures:
  
 

 
 
Air conditioning hose is one of the rubber hoses that we have been promoting. Quality is priority, for air conditioning hose, quality is very stable. It is one of our high-end hose. the synthetic rubber content for this hose is up to 40%, which is high in the range of rubber hoses.
