RectorSeal 45315 Ac Leak Freeze Pro Sealant, 1.5 oz. Cartridge

I like how it seals the leaks. I like the packaging too and the word "rector". We buy this a lot.

It does works at all, wastage of money. DO NOT BUY IT.

I added the green AC Leak Pro with magic charge to my heat pump last week. (was a free sample given me at a plumbing store) At that time I did not have a problem adding it. The leak which is in a geo-thermal heat pump water coil, has not decreased. I wanted to add a second new leak sealant but it was hard to find locally. I purchased the blue version without magic frost (all there was in the store) and because I did not have problems with the first, I purged my manifold with R-410a to the 1/4'' male inlet threads on the product and left fitting loose as per instructions. I assumed that because there was a schraeder in the male end that it would hold the system gas when I screwed on the female end onto the suction line. WRONG ! WRONG ! WRONG ! All the leak sealant blew out the male end in an instant all over my control boards ! This system needs to be simplified and improved. It is NOT satisfactory as is. A better approach is to purge your bottle refrigerant through your manifold first, (after all, you will have to add more, right ?) purge any air at the male end, and screw the brass fitting snug on the male end. At this point nothing would blow out there. Then quickly screw the female (feed) end onto the suction line. You should only lose a wisp of gas.
