Note: the use of AL801G in the home exchange area, please see, there is no understanding, please contact with after sale. The other for each batch of foreign trade more than single quantity and shape of different possible surface pressure gauge calibration and images of different scales, but the scale is the same as the PSI pressure, air pressure joint picture 90 degrees, there may be more than a single stock is 180 degrees directly head, using the methods and functions are the same, please understand each customer. Thank you The bottle opener and the joint are plated with yellow, the quality is assured, and the use is assured.


Authentic R134A American Wei Chang agent can cooperate with this supplement tube.






Please read the instructions and the use of AL801G tube before use!!!

The product of the bottle opener interface thread M14 thread, used for domestic refrigerant bottle, if you have the additional inspection tools, please confirm the thread opener tool interface and the refrigerant bottle is consistent, if he is not clear please contact the owner. Please confirm the corkscrew thread when purchasing.

Note: domestic refrigerant bottle screw M14, do not need to ask the sales staff directly, take it, and now the domestic market fake refrigerant too much, refrigerant bottle thread standards are not the same, the refrigerant bottle screw is not standard, the standard M14 bottle oponer may be threaded or not too tight. Please select the majority of owners of domestic production of the giant refrigerant or South Korea imported refrigerant, their mouth connecting thread is relatively standard, if the choice of refrigerant bottle small factory production to see Italy owners to use the universal detection tube opener. The product link is below:

Lengthening tube


Standard tube

Note: the thread interface of R134A refrigerant bottle and other related air conditioner aerosol products in Europe and America is 1/2 thread.

The thread interface of R134A refrigerant bottles and other related air conditioner aerosol products in Asia, Japan and South Korea is M14 thread.

The detection of the pipe is left the bottle, left tube length is 10CM, the middle cooling pressure gauge, right tube length is 20CM, the right side is the automobile air conditioning low pressure quick connector.



Automotive air conditioning refrigerantDIYFilling supplement method

The refrigerant supplement of automobile air conditioner is as convenient and safe as that of tyre flushing.
Automotive air conditioning in general will each year about 10% of the loss of normal refrigerant, which is due to automobile air conditioning compressor sealing mode decision (automotive air conditioning compressor is half sealed). As long as we check the air conditioner regularly every year, we can supplement the refrigerant. No need to worry about the use of methods, below I tell you friend car DIY automotive air conditioning testing method of supplement. Friends can try to add refrigerant to their own hands.
Methods are as follows:
1. need to prepare a DIY test tube for automotive air conditioning.
2. a bottle of R134A refrigerant for vehicles
3. now to the car testing pressure: first DIY tube opener end of the thimble anti clockwise rotation to the top of the bottle opener, the refrigerant is screwed into the screw.
4. to identify the low voltage interface, generally in the left side of the hood, there is a blue or black hat, the hat has a L word, the small cap spin down.
5. will the car engine starting and open air blower AC switch, open to the maximum, run and wait for three minutes. Connect the DIY tube interface to the low voltage end of the automobile air conditioner.
After the 6.DIY tube is connected to the low voltage interface, the DIY tube pressure gauge will instantly be calibrated. At this time, the pressure gauge on the DIY pipe is consistent with the air conditioning system pressure, see the pressure gauge on the pressure gauge, you know the pressure in the system. How much pressure do you need to add the refrigerant? Then there is a knowledge note! The pressure in the automotive air conditioning system varies according to the ambient temperature. As shown below, the Fahrenheit temperature and air conditioning system pressure control and verification system in high pressure and low pressure system, high explained more than the normal value of the refrigerant system, it should add refrigerant. If the ambient temperature is 30 degrees, the pressure in the air conditioning system should be about 45PSI, and the refrigerant should be supplied less than 45PSI. Fahrenheit is a common temperature unit in the United States, thank you
The pressure of the low pressure gauge at ambient temperature (Fahrenheit), and the value of the following pressure gauge is the theoretical constant temperature. In general, the use of the car owners according to the constant temperature value, the small value to the small value minus 10PSI calculation to determine!
Fahrenheit 65 corresponds to 18.33 degrees Celsius system pressure 25-35PSI
Fahrenheit 70 corresponds to 21.11 degrees Celsius system pressure 35-40PSI
Fahrenheit 75 corresponds to 23.89 degrees Celsius system pressure 35-40PSI
Fahrenheit 80 corresponds to 26.67 degrees Celsius system pressure 40-50PSI
Fahrenheit 85 corresponds to 29.44 degrees Celsius system pressure 45-55PSI
Fahrenheit 90 corresponds to 32.22 degrees Celsius system pressure 45-55PSI
Fahrenheit 95 corresponds to 35 degrees Celsius system pressure 50-55PSI
Fahrenheit 100 corresponds to 37.78 degrees Celsius system pressure 50-55PSI
Fahrenheit 105 corresponds to 40.56 degrees Celsius system pressure 50-55PSI
Fahrenheit 110 corresponds to 43.33 degrees Celsius system pressure 50-55PSI
7. low pressure air conditioning system, the need to add refrigerant, the bottle opener in the thimble clockwise, pierce the refrigerant bottle, bottle opener in the thimble immediately counter clockwise to the top, (Note: this time scale pressure gauge will show up to 100PSI to 110PSI, the scale pressure gauge 2 seconds after the time will slowly drop down. Dial back to its original display, this is normal, because the bottle is punctured, the pressure, a few seconds it shows the R134A bottle of the pressure in the bottle pressure by the compressor after absorption is shown as the pressure in the system!) Shake the refrigerant bottle, the refrigerant gas will flow into the system at the same time, see the pressure gauge, and the temperature and pressure of PSI units to be. Note: the refrigerant bottle should not be upside down!!! (except for oil mixtures)
Note: in the absence of pierce the refrigerant bottle, DIY tube has a little air, if the owner to need to drain a little air in the pipe, please according to the following method, in the absence of refrigerant bottles will pierce the refrigerant bottle opener and gently loosen a bit, then the DIY pipe in the air will be air conditioning system in the refrigerant to go out, then tighten the refrigerant bottle!!!
8. observed pressure gauge is normal, please immediately opener in a clockwise rotation to the lower end of the thimble and screw, remove the air conditioning system of low port connection. If one bottle is not enough, add second bottles of refrigerant according to the method described above, until the outside temperature and system pressure are up to one day.
9. at this time, the car air conditioning system refrigerant supplement to complete, please L small cap tightening.
Note: the above pressure scale and filling method is filling in refrigerant Sales USA ID and EF, completed a successful filling of my own, and will feel tire gas as convenient!
