R-410A Leak Stop & UV Dye Refrigerant — 28.2 oz One-Step Can with Gauge & Hose, 1/4″ SAE
This kit seals the leak, recharges the system, and marks the leak, all from one can. It's a 28.2 oz (1.8 lb) disposable can of R-410A blended with a polymer-free leak stop and UV dye, packaged with a reusable push-button gauge and a charging hose with a 1/4″ SAE fitting. The leak stop seals small leaks up to 300 microns as the refrigerant goes in, so there's no separate injector. If the leak is too large to seal, the dye shows where it is under a UV light. Already carry your own gauges? The R-410A leak stop can-only refill costs less.
Is the Leak Stop Gauge Kit the Right Choice?
This is the kit for a ducted R-410A air conditioner or heat pump that keeps losing a little charge from a slow leak. Instead of injecting sealant and refrigerant separately, you connect one hose to the system's 1/4″ service port, press the button, and watch the gauge while sealant, dye, and refrigerant go in together.
The leak stop is made for small leaks up to 300 microns. A larger leak needs a real repair, and that's where the UV dye earns its keep: it circulates with the refrigerant and glows at the leak point under UV light, saving time on the next visit. The gauge can be reused once the can is empty.
Ideal for: Ducted R-410A split systems and heat pumps with a 1/4″ service port that have a minor leak and need a top-off.
Need more capacity? Step up to the R-410A 25 lb Jug, Factory Sealed for full system charges once the leak has been repaired.
Leak stop performance depends on leak size and location; leaks larger than 300 microns require mechanical repair. Charging amounts vary with system size, line-set length, and ambient conditions.

Frequently Asked Questions
How large a leak can the leak stop seal?
The polymer-free formula seals small leaks up to 300 microns. Larger leaks need a mechanical repair; the UV dye helps you find them.
Do I need a separate sealant injector?
No. The leak stop and dye are already blended into the R-410A, so they go in with the refrigerant through the included hose.
How do I find the leak with the UV dye?
After charging, run the system so the dye circulates, then scan joints, coils, and fittings with a UV light. The dye glows where refrigerant escapes. You can confirm it with an electronic tool such as the TradePro refrigerant leak detector.
Can this kit charge a mini split?
Not without an adapter, because mini splits use a 5/16″ service port. The mini split R-410A leak stop kit includes the 5/16″-to-1/4″ adapter.
What if I only need refrigerant without leak stop?
For a leak-free system, choose the standard R-410A 28.2 oz can with gauge and hose, which has no sealant or dye.
Can this go into an R-22, R-32, or R-454B system?
No. This product is R-410A and must only be used in R-410A equipment. Check the refrigerant type on the outdoor unit's data plate before charging.
