R134a R22 HVAC AC gauge manifold set

We offering an affordable aircon charging manifold set mainly for automotive R134a and old R22 systems which has red hose for hot side and blue hose for low or cold side. Yellow hose is for the service port which always connects to the middle port on the aircon manifold gauge. In the middle of the gauge manifold there is also a sight glass where you can verify the charging process. When the refrigerant goes through your AC gauge manifold then you will see the refrigerant on the sight glass in liquid form. You can also see if you use additives such as PAG oil or leak detector liquid. You will see the oil going in or out of the automotive AC charging manifold gauge.

Features:

* The gauge scale is for R134a, R22. R410a and R404a gases.
* Incredible 70inch (1.75 meter) long hose. 
* 2pcs of R410a matching fitting / adaptor
* 2pcs of R22 matching fitting (Imperial and Metric)
* Other 4 can tap valves
* Top quality plastic case

You won't get this value for money anywhere else but from us.

As the most important part to do HVAC job we offer a full kit of AC gauge kit which includes all necessary parts. Although the AC gauge ports are not color coded but the hoses are in color red, yellow and blue.
Red means high pressure and they are to be connected to the aircon's discharge or liquid line valve. Blue means low side. These HVAC gauge manifolds allow the technician to measure the pressure on both sides.
The aircon gauges manifold also has a Schrader valve which is on the middle port of the manifold. This is for to purge / empty the charging hose from the air before you start the charging process. You can press the Schrader valve to let the air out. When the hose got purged you will feel the cold refrigerant coming out through the Schrader valve. Then you stop pressing the valve, your hose has been fully purged.

All value appearing on the read are atmospheric or vacuum pressure. The vacuum is measured from zero below atmospheric pressure to 30 in. Hg.
Please check all of our pictures before you place your order and make sure that our AC gauges show all data you will need to do your automotive air conditioning recharge job.
HVAC pressure temperature chart is not provided with the kit but we attached it below.
