Can I use this hose to recharge my car's AC myself?

Yes, on R134a systems. The can tap takes a refrigerant can and the 13mm quick coupler fits the low-side service port. Add refrigerant in short bursts while watching the gauge, and stop when the low-side pressure reaches the range your manual specifies.

Does it work on R12 and R22 systems out of the box?

The hose is listed as compatible, but the coupler is sized for R134a low-side ports. R12 and R22 systems usually need a thread or port adapter, which is not included.

What pressure should the gauge read?

Low-side pressure depends on ambient temperature and the refrigerant, so there is no single number. Use the chart for your system and refrigerant, and treat the color bands as a rough guide only.

Can it tell me if my AC has a leak or is low on refrigerant?

It shows low-side pressure, which hints at a charge problem, but it cannot confirm a leak. A proper leak test needs UV dye, nitrogen or an electronic detector.

What comes in the box?

One refrigerant charging hose with the pressure gauge, can tap and 13mm R134a quick coupler attached. No adapters, refrigerant or cans are included.
