I just obtained 3 broken acetylene regulators from work. All three have working gauges, just the regulators do not regulate, which is bad for acetylene, over 15 psi it becomes unstable, 30 psi = boom. Anywho, I've been thinking about getting gauges for future projects, and was wondering is anyone had any suggestions about not using them for brewing related purposes. There are 6 total, all are pipe thread style, 3 of them read 0-15 with a redline to 30 psi, the other 3 read from 0-4000 psi (I believe). None of them say anything along the lines of "for acetylene use only". Actually, the only thing they have on them is the pressure readings, "psi" unit marking, and a company name.
Any reason not to use them?
