Auto car A/C air conditioning manifold gauges connecting and using them

The gauges are very good quality who ever made them new exactly what was needed , and tick all the boxes that I was looking for which were needed to do all automotive refrigerants R22 to R437a which is the older gas used and was replaced around mid 90s to R134a which is the gas used in main bulk of cars today, in 2017 gas was updated to R1234yf. So basically the gauges cover all cars. Also good clear gauges a sight glass for viewing refrigerant when topping up, good length of hoses which give extra portability and it helps when refilling as it helps prevent overloading compressor with liquid refrigerant. You will still need to be careful though as overloading the compressor can damage it so be-careful if you refill with compressor off turn compressor over a few time to prevent lock up or only put in a little bit of refrigerant at a time. the kit also comes with all the necessary adapters to cover you for all the gases which saves you a nightmare finding the correct ones to fit your equipment. The kit also comes with all the adapters to refill using small cans and larger bottles of gases. 

The gauges show different temperatures for the gases and more advanced fault finding 

Obviously the gauges manifold are also made of metal so durable and have a hook to hook to the bonnet clip whilst in use and it includes connectors on the side of the manifold to store the hoses when not in use to protect against damage and to not allow dust into the hoses. 

Use the hook to hang the A/C gauges from make sure they are secure and will not twist loose or fall.

Connect the low and high side connections and check the pipes are tight to prevent leaks before turn the Schrader valve actuator pin down to open valve 

You do not have to open the low high valves on the manifold to get a reading and unfortunately there is no gas in this cars a/c system so I need to check for leaks ill do post on that asap.

see videos below of connecting and using these gauges

A/C connecting and using the manifold gauges on this system there is no gas so not much i can do but i show connection and some other advice regards using these gauges.

This car has static pressure and clutch kicks in on the compressor but the readings low and high pressure sides are still very low so could need topping up
