JACO FlowPro Digital Tire Inflator with Pressure Gauge - 200 PSI

I bought this item for the valve stem locking mechanism, and the ability to get accurate readings to with in 1/2 pound increments. I’m very happy with the item so far but it’s only been a month. The key to success with this new high tech featured item is how it will last. My last one was the standard analog with an old metered dial. It went 20 years, I doubt this one will go that long but I do like how easy and accurate it is.I use this at the race track and airing the tires properly is critical. So far it’s worked great. If it last getting thrown around at the track and packed up many times in the tool boxes I’d be grateful.

Great product and easy to use and very accurate.

Got the JACO FlowPro digital tire inflator gauge today just 2 days after ordering. Came w/ 2 AAA batteries already installed. I just pulled the insulator strip, and it lit up!. "00.0 psi". Came w/ a quick disconnect male air hose fitting AND a small roll of Teflon tape (what, no wrench?)! I've got a couple of mechanical dial gauges that I trust, (but they're not inflators), so I compared the JACO to them on a tire w/ 37 psi. They all read within 0.5 psi of each other! This comparison was done using the JACO as a gauge w/o an air compressor hose connected. It lights up (wakes up?) and reads tire pressure as soon as it's straight clip-on hits the tire valve. It bleeds off (goes to 00.0 psi) as the clip-on is removed from the tire valve. The last gauge reading stays lit for 2 mins, then goes dark. The 2 AAA batteries will probably have to be replaced in about 10-15 yrs. from now. The gauge is activated to "On" again simply by pressurizing it. That's nice. No switch to turn on/off. And it always comes up w/ the units you set (psi for me) w/o having to choose every time you use it.Using the tape provided, I installed the air hose fitting (after checking for correct fit-up to my quick disconnect compressor hose chuck), snapped in onto the hose, and squeezed the trigger. W/o being connected to a tire, the gauge showed the compressor's tank pressure w/o leaking or blowing any air through it's straight clip/chuck. How cool is that!! Push the bleed off, and it goes back to 00.0 psi.So here's the big test: Inflating the rear tire of my motorcycle. The rear tire valve is only visible for 25*-30* (out of 360) next to the floor, under the muffler and rear cog. Indian m/c owners will understand. Unless you have a big m/c lift to get this monster up a couple feet, you'll be laying on your side on a concrete floor (if you're lucky). Once I got it clipped onto the valve, the gauge read the same as the bike's TPMS. Great! Squeeze the trigger, let off and read the pressure. Repeat. Opps! Went too far. Wanted 41 psi, but got 42.5. No sweat. Push the bleed off button, read, repeat. And it's right there. 41.0 psi. Pull the clip chuck off the tire valve and I'm done (well ok; replace the valve stem cap.). That was so much fun that I did the front tire (it's much easier) just for laughs.Finally after my 50 yr. collection of pressure gauges, inflators, inflator-gauges, and air chucks of all shapes, I've got something that works as it should. Right out of the box. Batteries included, Teflon tape included, air hose fitting included, and even a tire valve screw-on fitting (if you don't like the clip-on) is included. You can read it in the dark, it's dead accurate as far as I know (in the 36-41 psi range that I tested), reads in 0.5 psi increments (didn't try any of the other 3 units) supposedly up to 200 psi, will read upstream and downstream pressure, turns itself on and off, and won't break the bank. What's not to like? Thanks JACO.BTW, I do very few reviews (can't ya tell?), but for this device I had to give my 2 cents. Also, I did not receive any compensation for this review, nor do I know anyone from JACO. I paid the full amount from Amazon, got it 2 days later, and wrote this the same day. I tested it in 65* F temps., so I can't speak to how it'll work in temperature or pressure extremes. Also, I can't say how much abuse it'll take (I'm a home mechanic) in a commercial environment.

This is a quality product. Comes with batteries already installed. As soon as you connect to an air valve this unit automatically turns on and displays air pressure. Numbers are big and easy to read. You can use it without connecting to air compressor as a tire gauge. The deflator button is a great feature as well.

Reviewed: 2025-07-23Revised: 2025-08-08The push-on tire connector seals well enough, but often requires pressing and holding onto the tire stem further to obtain maximum flow. The valve body seems well built and the valve is easy to modulate, so I'm satisfied with that part.I've had problems with accuracy, however. For quite some time, the JACO was reading about 12PSI low on a 35PSI car tire with the difference varying with pressure. If I filled a truck tire to 50PSI on the JACO, the actual pressure would be 70PSI.I reported this in the first version of my review and JACO kindly offered to refund the full purchase price, so it's good that the company is responding to negative reviews by offering refunds. However, I did not accept the refund and thus paid full price for this product.Instead, I tried to find a calibration mode on the product as I found instructions for calibrating another model that looks exactly the same. However, this proved fruitless as that method did not enable a calibration mode in this model and I could find no other combination of key presses/holds that would do so.I did take out the batteries and re-insert them and this appears to have reset the gauge electronics. Afterward, accuracy was nearly perfect again.I cannot give the product the highest rating because I can't fully trust it; I will not know whether it's showing an accurate pressure or not unless I compare it against a known accurate gauge. However, I have raised the rating from 2 stars to 4 due to the "reset" in accuracy combined with the company's offer of a refund.As most people misuse the rating system, I feel compelled to explain that a "good" product that does exactly what it claims to in an average manner is worthy of 3/5 stars. Above-average = 4/5 and class-leading = 5/5.

Got this along with the presta valve attachment. Works well and great for the price. Time will tell how long it lasts but it seems durable enough for medium home use. The presta valve attachment works better than expected. Very happy and would buy this again.
