4" All Stainless Steel Oil Filled Vacuum Pressure Gauge - 1/4" NPT Lower Mount, 30HG/0PSI

I'm going to use this as part of a fuel pressure test tool I'm assembling. It will be used daily in a professional environment diagnosing running problems with fuel-injected vehicles. Don't know yet if it will be suitable, accurate, or durable, but the initial appearance & impression is a solid professional gauge. If looks mean anything, this should be a great tool. Updates after it has been used awhile.

Very nice gage at a very nice price. Very accurate and very repeatable. I use this as a high end tire pressure gage.

The first time I used this gauge, the rubber cap popped off and the oil leaked everywhere. I'm not sure what "metal knob" that the label is referring to, as there was no metal knob to be found. Maybe this is why the oil was leaking to begin with. I believe that it came without a metal knob and was useless upon arrival. Now there's oil all over my work bench.Edit: I have received a new pressure gauge from the manufacturer and this one has a brass knob in the rubber grommet. I will update again based on product performance.

Wonderful guage, love it. Constantly testing fuel delivery vacuum daily. Easy to read, nice and steady.

1st class all the way!

Just what I needed and ordered -- works and fits perfectly!

Used these gauges for building a manifold test set. Excellent well built gauges. Delivery was less than perfect at no fault of amazon but they we’re happy too help..

Very good quality.
