This is a DIY recharge kit for R410A systems: a 1.8 lb can of refrigerant, a polymer-free leak stop, UV dye, a charging hose with pressure gauge and a 5/16-inch brass adapter. It suits homeowners topping up a mini split, heat pump or central AC who also want to find and slow small leaks. Against plain recharge cans it adds leak sealing and dye detection in one package, but it is not a substitute for finding and fixing a major leak or for a technician's recovery equipment.

Rated 4.5 out of 5 from 126 ratings. Buyers generally report the kit is easy to connect and works for small top-ups, while some note the refrigerant amount is limited and the leak stop is no cure for a real leak.
This R410A repair kit recharges systems that run low on refrigerant and helps seal many small refrigerant leaks. It combines 1.8 lb of R410A refrigerant, a polymer-free leak stop, UV leak detection dye, a charging hose with a pressure gauge, and a 5/16" brass adapter. No separate injector tool is needed.
The hose has push-button charging and a color pressure gauge. A double check valve helps prevent refrigerant backflow during charging. The can is self-sealing, so you can use only what you need and save the rest. The UV dye stays in the system and makes future leaks easier to find with a UV inspection light.
It is for systems that use R410A refrigerant, including mini splits, heat pumps, and residential central air conditioners, both ducted and ductless. The 5/16" brass adapter connects to most R410A mini split service ports. Low refrigerant usually points to a leak. Large leaks, damaged components, or mechanical failures should be repaired before recharging, and the equipment manufacturer's charging procedures should be followed.
