Hey everyone I have a Oil Pressure Gauge I received from Mr. Bill Cody for my new GAST pump when I put it in. It would appear its getting a bit low on oil in the face of the gauge. I was wondering if I can add a certain type of oil to this gauge with the small hole on the top of the gauge? When I first got the gauge it was about 3/4 or so full. It had a small air bubble at the top which Bill said was fine it needs to be that way. But my small air bubble is almost half of the gauge now... So if I can put oil in it through that small hole my next question would be of course what type of oil?
Thanks,
RC
The leak may be minor, but the fluid level should never drop. If no oily, dusty residue is visible on the outside of the gauge or plug, chances are the diaphragm separating the gauge from the system has failed and it is leaking into your system, and giving a false reading...I'd replace it or try getting it warranted.
I thought most liquid filled gauges used mineral oil, few gauges are compatible for use on/with compressed oxygen due to spontaneous combustion hazards.....? No explosion/combustion hazard with silicone or glycerin, right? (unless mixing glycerin with potassium permanganate)
