I got an oxy-propane cutting set for Christmas & the torch has Male connectors .650” Dia & 25TPI (LH & RH) as far as my eyes can make out without going into a freezing garage to dig out the thread guage. I have an old oxy-acetylene welding torch (no name) that came in a box of goodies years ago & never used by me (haven't had more than propane before). Measuring the male threads on that they seem to be .50”X25TPI.
What are these threads normally – I’ve never used anything other than plain propane before? Might they be GAS which AFAIK is 26 TPI for all normal diameters? Can I readily buy adapters to use the torch on my new hoses for brazing, or is it a make-it-yourself job?
P.S.
I know that you can’t weld with oxy-propane, but working on my tractor steering knuckles recently prompted the need for better than plain propane heat.
