R-32 Refrigerant 28.2 oz One-Step Can with Gauge & Hose — 1/4″ SAE Connection
Everything you need to top off an R-32 system comes in one box: a 28.2 oz (1.8 lb) disposable can of low-GWP A2L refrigerant, a reusable pressure gauge, and a charging hose with a 1/4″ SAE fitting. Connect the hose to the can and the system's service port, press the button, and watch the gauge as you charge. This version is built for ducted R-32 split systems and heat pumps with a standard 1/4″ service port. Servicing a ductless unit instead? The mini split R-32 recharge kit adds the 5/16″ adapter mini splits require.
Is the Gauge & Hose Kit the Right Fit?
This is the choice for a quick, one-handed top-off without setting up a full manifold. The included gauge and hose let you add a small amount of refrigerant and check pressure in the same step, and the gauge can be reused on future cans.
Important gauge note: the included gauge does not currently show an R-32 scale. Read it on the R-410A scale, since the two refrigerants run at nearly identical pressures. Reference values: R-410A at 130 psig suction / 429 psig discharge, and R-32 at 133 psig suction / 430 psig discharge.
Ideal for: Topping off ducted R-32 central air conditioners and heat pumps with a 1/4″ service port after a leak repair or a minor charge adjustment.

Charging guidelines and pressure references are general information only. Actual requirements depend on system design, line-set length, ambient conditions, and the amount of refrigerant lost. R-32 is an A2L refrigerant for use by qualified, EPA 608 certified HVAC/R technicians. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
The gauge doesn't show R-32. How do I read it?
Use the R-410A scale. R-32 and R-410A operate at nearly identical pressures; for reference, R-410A runs about 130 psig suction / 429 psig discharge and R-32 about 133 psig suction / 430 psig discharge.
How do I charge with the one-step can?
Connect the charging hose to the can and to the system's 1/4″ service port, then press the button to add refrigerant while watching the gauge. Follow the equipment manufacturer's charging procedure.
Can I reuse the gauge with another can?
Yes. The gauge and hose are reusable. When you need more refrigerant, the R-32 28.2 oz can-only refill threads onto the same hose.
Will this connect to a ductless mini split?
Not directly. Mini splits use a 5/16″ service port, and this kit ends in a 1/4″ fitting. Choose the mini split R-32 recharge kit, which includes the 5/16″-to-1/4″ adapter.
Is R-32 compatible with R-22 equipment?
No. R-32 only goes into systems designed for R-32. It cannot be added to R-22, R-410A, R-454B, or any other refrigerant system.
Is a full manifold gauge set better for A2L work?
For full diagnostics, many techs prefer a full manifold. The NAVAC A2L-compatible analog manifold gauge covers R-32, R-454B, R-410A, and R-22.
