This is standard in regulator construction for safety reasons.   All the 
high pressure side has left hand threads and the low pressure side has 
right hand threads so you don't mess up and screw something into the wrong 
hole, thus blowing up something that was not designed to handle the high 
pressure.  All high pressure gauges will have left hand theads.  You will 
find it easier to find a left hand thread gauge of the right capacity than 
a right hand thread.   Ask the maker of your regulator about spare parts.
