A/C units repIacing R22 with R134a
Has anyone replaced their R22 with R134a ? I bought a can of the R134a which came with a cheap guage and hose but it will not connect to the R22 fittings. Can anyone direct me to exactly what fitting I need to charge with these throwaway cans. I bought a R12 to R134a fitting thinking R12 & R22 took the same fitting but no joy.
Yes I know all the negatives but this is`a rusted out piece of crap with a slow leak that I want to squeak through the rest of the season.
