This is a far superior thread lubricant and it is also good for o-rings and other refrigerant fittings. I put a dab on my 134a couplers before connecting because it helps seal better.Don't put pag oil on fittings and orings use mineral oil it doesnt draw moisture like pag. Using pag oil on threads will cause thread corrosion and seize them.Pag oil should be used in the system just not at fittings.
