0-4500 PSI gauge
Brass construction
1/4 NPT thread (to suit most regulators)

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. Best to use a small dab of Thread Lock glue on the threads. Let this cure for 24 hours to ensure a sela.

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. If you don't want to have to replace your gauges again save yourself the hassle and get one of these gauge guards.  You will not regret it!

Remember to also use a dab of Thread Lock glue
