This is a 28.2 oz disposable can of R-410A pre-blended with a polymer-free leak stop and UV dye, sold with a reusable push-button gauge and a charging hose with a 1/4" SAE fitting. It seals small leaks up to 300 microns while it recharges, and the dye marks leaks too large to seal so they can be found under UV light. It suits ducted R-410A split systems and heat pumps with a slow leak and a standard 1/4" service port. Against buying sealant and refrigerant separately, it saves a service step, but it is not a repair for a large leak and the can is disposable.

This is a 28.2 oz (1.8 lb) disposable can of R-410A refrigerant pre-blended with a polymer-free leak stop and UV dye. It comes 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 no separate injector is needed.
Connect the hose to the system's 1/4" service port, press the button, and watch the gauge while the sealant, dye and refrigerant go in together. If a leak is too large to seal, the UV dye circulates with the refrigerant and glows at the leak point under a UV light. Leaks larger than 300 microns require a mechanical repair.
It is for ducted R-410A split systems and heat pumps with a 1/4" service port. Use it only in R-410A equipment, and check the refrigerant type on the outdoor unit's data plate before charging. Charging amounts vary with system size, line-set length and ambient conditions. It is for use by qualified HVAC/R technicians.
