If you are looking here you have probably just damaged or busted your regulator gauge. Luckily they are easy to replace.  Just un-screw the gauge and then screw in the new one.

These regulator gauges can also be used on many other devices as the 1/4 NPT thread is fairly standard and it will suit most standard regulators.  Annoyingly Micromatic use an unusual Left Hand thread so this gauge will not fit Micromatic regulators but almost all other regulators will be compatible.

Gauges are delicate bits of equipment and they can easily get damaged even with a light knock.  We really recommend customers getting a gauge gaurd.  If you don't want to have to replace your gauges again save yourself the hasstle and get one of these gauge guards.  You will not regret it!

Here is a video to show you how to fit the gauges:
