Accu-Gage by Milton Presta Valve Bike Tire Pressure Gauge with Bleeder Valve, for 0-60 PSI - ANSI Certified

Quality product, would not be w/o one.

Over the years, I’ve tried other bicycle tire guages, including at least two electronic ones. None of those proved satisfactory because of releasing air when attaching and removing them from the valve stem. Because of its design, however, this one is a keeper. The seal that encapsulates the valve stem is deeper into the guage’s barrel and creates a good seal. When inserted squarely on the valve stem, it neither leaks air when inserted or removed. Needless to say, I am most pleased with this item.

I did not trust the supplied gauge since anything with the stated accuracy would also cost quite a lot. So I bought this gauge for the presta adapter and added a $20 from my favorite yellow industrial supply company. This gauge is liquid filled, rated for 1% accuracy, and has a bigger 2.5" face so it can be read accurately. The threads on the adapter are 1/8" NPT, and I had to get a 1/4 female to 1/8 male brass fitting to add my 1/4" NPT gauge. I am very happy with the construction and machining of the presta adapter. It uses a short section of silicone hose to seal to the valve stem, and this could be gotten from an industrial supply house as well if it wears out. The fit is tight, so it stays on the valve stem without having to be held on. The result is a ~$35 gauge that I can really trust as I experiment with lower tire pressures. I found the gauge on my ancient Silca floor pump to be over 10% low compared to this gauge! If you have spent the money to move to tubeless tires, it would be well worth it to use a gauge like this to ensure that you are getting the most out of them.

Milton still makes Schrader pressure gauges in the USA, but their Accu-Gage line is strictly from China. I was hoping that would not be the case, but my fears were realized.Despite that, the product was very solid out of the plastic box, attached firmly and securely to my bike's Presta valve, and took an accurate reading. The same could not be said for the absolutely horrible SKS Airchecker Digital Pressure Gauge that I returned yesterday.I wish more products were made in the USA, because the quality is better, but it is what it is.

Fit it on valve and the pressure reading is maintained after you remove from valve. Maybe a bit too heavy to take on long bike packing trips where every gram counts.,

The media could not be loaded. I purchased this gauged because I thought it was a Milton gauge. However, it doesn’t perform at the Milton level. I used it on three occasions before the gauge needle jammed up.I took it apart and ran some performance tests on it and discovered that the gear mechanism “skips” teeth each time “pressure” is released. Eventually, it gets to a point where you can’t release “pressure”.The gauge operates by moving that half moon coil seen in the photo where my fingers are on it. Squeeze closed “pressure” goes up, spread apart and “pressure” goes down. I am able to reset it each time it gets stuck (runs out of teeth on the gear mechanism) but it’s an aggravation as it only lasts a few uses at best before I need to take it apart and reset it.Skips: The gear mechanism “walks” on each use but doesn’t “walk” back the same amount on each “pressure” release. Eventually it runs out of teeth.Pressure: Pressure from an inflated tire moves the half moon coil and the release button also moves the same half moon coil in the opposite direction. This moves an arm that has teeth on it. The backside of the needle has the other set of teeth. When it is jammed on 10-15 psi there is no pressure in the gauge. It’s just a gear set that ran out of teeth.I used a phillips and small flat head screwdriver to open it.

This guage holds its pressure so you can take it off and still read it. I also like the button that allows you to release pressure until it gets down into the range you want it. Works perfectly.

This is the fanciest tire gauge I have ever got. I am new to presta valves. All my previous bikes I ran schrader valves. So I just used the long skinny tire gauge sold for auto tires. This one works pretty slick. I really like the pressure blead off feature. The gauge does not move when you bleed off pressure though. I have the fancy anodized valve stems and it has wore away some of the anodizing with repeated use. To be fair the anodizing was pretty crappy anyway. I am happy with my purchase.
