Soldering PSI Rating

  1. May 26, 2016 #1
    How much PSI can solder take if used on 1/4" threads to connect a air tank and a valve. I think without the solder it will leak air because the threads aren't perfect and i am using a co2 tank

    You must not do this . Sealing up mismatched and badly fitting threads to prevent leaks is a dangerous practice .
