REPLACEMENT HIGH GAUGE RHT

This replacement gauge for the high pressure side has right hand threads. This means that the "righty tighty, lefty loosey" rule does apply. To tighten this gauge, turn to the right; to loosen this gauge, turn to the left. Most regulators (about 80%) are set up with this style of threading on the high pressure side. If your regulator does not have right hand threading, this gauge will not attach.
