Review on Screw Pressure Gauge for Spare Air by Trevor Blazis

Gauge leaking during installation. Replacement ordered - the same. Yes, I used a silicone trident. Factory new 300 N, - with pin gauge that holds air. The used gauge O-ring and dial indicator worked. dial stock. I have contacted the spare air, I hope they at least send me some o-rings? IF your gauge is leaking - try a pin o-ring or a new o-ring. I was about to give it a star just because it's a hassle to re-order and return - and need to replace the o-ring. But I stopped at two because the second sensor is upside down, the first was slanted.
