We have a little problem that some of you might know the answer to.
We use primarily Hoke torches. For years we used propane and oxygen.
About 3 years ago I moved to a bigger shop and we switched to
natural gas with a Gas-tec booster (that is working out great by the
way). I called 3-4 suppliers to ask whether we needed to replace our
propane/02 Hokes with natural gas/02 Hokes? They either didn’t know
or said it didn’t matter. We needed 2-3 new torches and those were
nat. gas/02, but the rest are the old propane versions (and they all
seemed to work equally well). What has happened is that we have had
2 of the propane Hokes begin to leak. We can smell gas when
everything is off. We stick the torch tips in water and you can see
little bubbles. We replaced the torches.
The question is, are these leaking because the valves have worn out
or because they were made for propane and we are using them for nat.
gas? Another question, can we repair the leakers?
