SIMMONS MFG 1305 100PSI 1/4" PRESURE Gauge

It’s on my well pressure tank that serves a deep sink in my log cabin and I didn’t want to use a tee on the tank without a pressure gauge. I really don’t care if it’s accurate but it does seem to be so that’s a plus. It is consistent in the pressure it reads when the tank tops off and the well pump shuts off and I really only needed it to have a visual clue if the pressure was getting too high. The price was right at about 6-bucks and it doesn’t leak so it works for me.

Nice gauges. Just not exactly what was pictured.

Easily installed and works as intended. Great quality product!

Works for my application. Use Teflon tape. Don't over tighten the brass against the plastic if you are using plastic fittings. It is filled with a viscous fluid. By design.

First, I'm an engineer so I know what I'm talking about. One of the reviewers said this device was filled with a viscous fluid. That is totally false as this is a water gauge, which are filled with air.As received, mine read just under 10-lbs of pressure, whereas the needle should have been resting on the peg which is a little above zero. Apparently there is no 100% visual inspection before parts leave the factory. I perhaps should have, and definitely could have, returned it. But I know how they work and I know how to fix them, so I decided to keep it and fix it. I've already taken it apart for that purpose but haven't gotten around to fixing it, but probably will fairly soon. After opening it I found two points of visible damage which any assembler (or inspector) could have easily caught before final assembly -- a critical part in its mechanism had two deep dents in it which would have (and did) cause the problem. So shame on the manufacturer for shipping it. The dents cannot be removed but I can still zero the meter, though the dents will cause a slight change in accuracy over the whole scale (which I'm not going to be that sensitive to -- AKA willing to overlook). If I did not know how to zero the meter I would have returned it because its reading would have been way off over the entire stale (and that's way beyond my ability to forgive).Warning: since water gauges retain water within them after use, and is very difficult to entirely remove without cooking the device, never leave it out at temperatures below freezing. When water freezes, it expands. That expansion will be permanent and will totally ruin the most critical component within the meter -- the component that is dented in my meter -- and you will end up throwing it away.

It functions very well. Accurate.

Great fulfillment service. Product is pretty standard. Works fine installed in my we'll water supply system.
