MEANLIN MEASURE2pcs 0~15Psi Stainless Steel Liquid Filled, 1/8" NPT 1.5" Glycerin Filled Fuel Pressure Gauge, Water Oil Gas, Lower Mount, with 1/8" x 1/4" NPT and 1/8" x 3/8" NPT Hex Bushing

Cheap and seems very durable. Good buy.

Good product, good price and looks good.After following instructions for installation, gauge fits very good, no water leaks and very accurateUsed on my pool filter to let me know water pressure in order to let me know when to clean the filter (15 to 20 #’s of pressure)👍👍

Bought this for a craftsman torpedo heater someone threw in the trash by the road. Cleaned it up, found the issue in 5 minutes and works fine. But the flame seem slightly more then needed. This heater had no guage to read pressures only a adjustment screw. Found info online what pressure its was suppose to read. Researched this guage online and tried it. It has a fluid inside the dial face, probably some sort of oil and is sealed. But research the guage needed before you buy. The connection my heater has to put on a dial guage is on is at the back and has a grill cover just big enough to get to adjustment knob for the flame adjustment and a dial guage. But the threads on the bottom of the guage is to short to fit with the heater grill in place. This guage has threads out the bottom of the guage. Some guages have them out the back. You will need to see which one is best for your heater. Easy fix for me. Went to Menards in plumbing dept. and found brass female adapter on both ends that was about 3/4"long that would fit the threads on the guage. Then added a 1 1/2" male adapter threaded on both ends the same size as guage threads that would fit the female adapter. Put plumbers tape on the threads to help seal it and it threaded right into the heater and was outside the grill so it could be read. Fired up the heater and found it was adjusted to high. Adjusted it to 4.7psi and heater works perfect. The oil in the guage helped the needle from jumping around. Seen many guages on videos that had no fluid in them and as the heater was running the needle vibrated bad enough the needle would deviate + or - 2 lbs. This guage stayed perfectly steady even as I adjusted it. Not sure what the fluid is, but some sort of clear oil. I removed the guage to be safe in the winter as I did not want to take chance of this fluid getting to cold when not in use and freeze. Dont think it would happen but I was just cautious. The the guage worked great and would recommend it.

Works good as I needed a small face to get into a spot. Cost effective and quick delivery.

The price of this whole kit is the price of just the 1/8" NPT adapter everywhere else. The gauge and adapter feel well made and durable. As far as oil pressure gauges go, if you're on a budget fluid gauges are definitely the better choice. And electronic oil pressure gauge will be in consistent and inaccurate at times, unlike this gauge. It worked great for my needs and at a great price.

I used one of these to add a pressure readout to my laser engraver external air assist setup. Made a very professional looking setup and really helps dial in different settings for each material. Great product!

Leaked immmediately. Leaked from where the gauge screws on. Needs to come with teflon tape or something!

Works good.

Looks to be good quality haven’t gotten it installed yet but looks good

Gauge works ok but mounting is not as pictured, the pipe fitting comes in from back ,made it hard to use in my application

Accurately Very good working .

The ad clearly states the gauge is 0 to 15 psi. In actual fact, the 2 gauges I received were 0 to 30 psi.
