2-1/2" Oil Filled Pressure Gauge, Stainless Steel Case, 0-15 PSI, 1/4" NPT

Purchased this gauge and a different one also for our fire dept. to use in hydrant flow testing. Worked very well, easy to take readings and was packaged well. Would recommend.

value for price is great, and quality is comparable to some of the higher end gauges I use at work. I seemed to loose about 0.5 psi resolution after a few uses (in the freezing dead of winter, outdoors), but for a 15 psi gauge, I expected some drift. The company appears to carry other very reasonably priced valves and other hardware (not through Amazon, but they will send you a info in your shipment).

Works great thanks

This gauge is about the least expensive that you'll find out there that's liquid filled, and it's great for low pressure leak testing of sealed systems (and other uses, but this is what I'm using it for). For the money, it is significantly better than most, if not all, non-liquid filled gauges, most of which tend to stick. After running a gas leak test at say 10 psi for a while, many cheap gauges won't indicate a reduction in pressure right away as you bleed off pressure... they'll hang for a bit and then suddenly jump down a few PSI. This means that during the test, you need to "flick" them a few times periodically to overcome their getting stuck to discover whether or not any pressure has leaked. This gauge operates very smoothly, no "flicking" required. Bleed off 1/10 psi and you'll see the gauge drop a smidge. The only reason for a 4 star rating vs 5 is that after running a 24 hour test at 9 psi, I discovered what I believe was a slight amount of pressure that leaked though the gauge. Prior to the test, I removed any internal pressure in the gauge by pulling the little "valve" in the top of the gauge... but after the test, which indicated a few tenths of a psi pressure drop, there was pressure built up in the gauge again. Outside temperature was virtually identical at the start and end of the test, so it appears this slight pressure drop was not a system leak, but in fact was leaked thru the gauge. I ran another 24 hour test using a different gauge, and there was no pressure drop after 24 hours. The bottom line on at least this one specific gauge: it's a great gauge for shorter duration tests where a microscopic leak thru the gauge won't have any measurable affect; but for a longer term test, you can expect a small pressure drop.

I welded a fitting on my Harmsco pool filter to mount the gauge to show the pressure drop as the the filter got dirty. It shows around 10 psi when clean and the Barracuda quits working around 3 psi. I was just curious about the pressure drop.

I tested it before using it for accuracy and it was perfect. Just make sure you vent it before you use it to your local atmosphere . Other wise it will not be accurate also make sure you hold it upright when pulling the plug and re-plugging the vent plug so oil does not spell out.

Attempted to use this to pressure test a fuel tank and after applying a few psi, the gauge stuck at around 3psi and now will not zero. There is a pressure relief valve and a sticker that instructs using it for this purpose however it does nothing for me.

Works very well
