Gauge problem!!

[krazydiamond]

Hey,
I'm helping a friend with his rodeo and everythings working fine except the gauge on the regulator rotates everytime I fire. I know he bought it used so I was wondering if it's missing something that will hold it steady or is there something else wrong that I don't know about? Would threadlock solve it? Any help is appreciated.

Thanks

What do you mean by rotates, do you mean the actual guage turns in the threading or the marker on the guage turns?
