This is a 28.2 oz disposable can of R-32 refrigerant sold with a reusable pressure gauge and a charging hose with a 1/4" SAE fitting. A press button releases refrigerant, so you can top off a ducted R-32 split system or heat pump and watch pressure in one step, without a full manifold set. R-32 has a GWP of 675 against 2,088 for R-410A and no ozone depletion, which is why new systems use it. The catch is the gauge: it has no R-32 scale, so you read it on the R-410A scale, which runs within a few psi of R-32. It suits small top-offs after a leak repair, not full charges; for those you need a jug.

Only a handful of ratings, averaging 4.2 out of 5. Buyers who mention it treat it as a convenient kit for small top-offs, and the main complaint is the gauge lacking an R-32 scale.
This kit has everything needed to top off an R-32 system in one box. It includes a 28.2 oz (1.8 lb) disposable can of R-32 refrigerant, a reusable pressure gauge, and a charging hose with a 1/4" SAE fitting. It is built for ducted R-32 split systems and heat pumps with a standard 1/4" service port.
To charge, connect the hose to the can and to the system's service port. Press the button to add refrigerant and watch the gauge as you charge. Follow the equipment manufacturer's charging procedure. The gauge and hose can be reused on future cans.
The gauge has no R-32 scale, so read it on the R-410A scale. The two refrigerants run at nearly identical pressures. R-410A is about 130 psig suction and 429 psig discharge. R-32 is about 133 psig suction and 430 psig discharge. The kit does not connect directly to a ductless mini split, which uses a 5/16" service port. R-32 only goes into systems designed for R-32. It is an A2L refrigerant for use by qualified, EPA 608 certified HVAC/R technicians.
