R-22 Refrigerant with UV Dye & Stop Leak — 28 oz One-Step Can with Gauge & Hose, 1/4″ Connection
Many homes and businesses still run on R-22 air conditioners and heat pumps. This kit is built to keep those older systems cooling: a 28 oz (1.8 lb) disposable one-step can of R-22 with stop leak and UV dye already blended in, plus a reusable gauge and a charging hose with a 1/4″ connection. Connect the hose to the can and the service port, press the button, and watch the gauge. The stop leak works on minor leaks, and the dye marks the leak so it's easier to find with a UV light. Already have gauges? The R-22 stop leak can-only refill costs less.
Is the R-22 Stop Leak Gauge Kit the Right Choice?
New production and import of R-22 ended in the U.S. in 2020, so many owners of older systems want to keep what they have running rather than replace equipment right away. This kit is for that situation: a legacy R-22 system that is slowly losing charge and needs a top-off.
Using a small can with a built-in gauge avoids opening a large cylinder for a minor job. The stop leak goes in with the refrigerant, with no separate injector. If the leak keeps coming back, the UV dye already in the system helps locate it for a permanent repair.
Ideal for: Topping off older R-22 central air conditioners and heat pumps with a 1/4″ service port that have a minor leak.
Need more capacity? Step up to the Freon R-22 30 lb Jug, Factory Sealed for larger charges on R-22 equipment.
Stop leak results depend on leak size and location; larger leaks require mechanical repair. Charging amounts vary with system size, line-set length, and ambient conditions. For use by qualified HVAC/R technicians. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Is R-22 still available?
New R-22 production and import ended in the U.S. in 2020, but existing supplies are still sold for servicing older equipment. This can lets you service an R-22 system without buying a large cylinder.
What does the UV dye do?
The dye circulates with the refrigerant and glows under a UV light where refrigerant escapes, so leaks the stop leak can't seal are easier to find.
How do I connect the gauge and hose?
Thread the hose onto the can and onto the system's 1/4″ service port, then press the button to charge while watching the gauge. Follow the equipment manufacturer's charging procedure.
Can I put R-22 into an R-410A system?
No. R-22 is only for equipment designed for R-22. Never mix it with R-410A, R-32, R-454B, or any other refrigerant.
Is there an R-22 replacement refrigerant?
R-407C is sold as an R-22 replacement. See the R-407C 25 lb jug, and consult the equipment manufacturer before converting a system.
What else helps pinpoint a stubborn leak?
Along with the UV dye, an electronic tool such as the TradePro refrigerant leak detector can help narrow down where the system is losing charge.
