| Howdy Stuart,
Well, I am not sure how much help I am going to be in this topic. I am a machinst by trade and I am also a mechanic where I work.....the mechanic was their idea not mine lol. However, the air gauge I have on my compressor and the one I have on my portable air tank are both made by "Festo" and are.... how shall I say this...... uh..."on loan from work" lol. Yes, I pilfered them. However in my defense, I have done several small paint jobs for the company throughout the plant using my own personal equipment.
But to your problem....I would just suggest that you go to your local hardware store or industrial supply company.
Of course there will probably be fittings you will need to go along with any gauge you get so the hardware store might be the best starting point. Be sure to purchase teflon "thread" tape to seal all connections.
I hope this helps.
Have a good day,
Greg |
