Oil additive/bonding/gasket friendly/"O" ring friendly/
teflon friendly/ neoprene friendly stuff called SUPER CHANGE ! When retrofitting an R22 system you don't have to change out the oil or any of the above! Has anyone used this stuff? It bonds mineral oil, alkylbenzene , and POE to each other, so no oil change out. Its by CLIPLIGHT Co. I've used their pin hole in evap coil sealing stuff with good results this year on one system. No more Freon leaks in the evap , so far.
