Milton S-506 Original Service Station Tire Inflator and Air Pressure Gauge, Dual Head Chuck, 1/4" NPT, 15" Rubber Hose, 10-160 PSI

The dual head chuck makes it easy to inflate tires at any angle, and the rubber hose is long enough for convenient use. The gauge provides accurate readings, and the build quality is top-notch. I’ve used it for all my vehicles, and it’s been reliable every time. Highly recommend it for anyone looking for a durable and accurate tire inflator!

USA MADE: BUY IT!Accuracy made easy.Checking tire PSI often is a must.This unit will last a lifetime.Stay away from cheap Chinese garbage, you'll be glad you did.

Worked in an Esso Station at 15 years old back in Pa.. I’m now 64 years young. This is identical to the air chuck we had back then and works just as well. Made well, gauge very visible and quality

The S-506 model now is a 160 lb gauge based on the Milton website information.This inflator gauge was bought as a gift for my son. It's essentially a duplicate of one that I've been using in my own garage for about 30 years except the scale was 160 on the new one instead of 120 like my original. I prefer the 120 lb scale since it's easier to calibrate and easier to read but I'd need my glasses for either scale now so it doesn't really matter much.This is a very convenient, very durable tool; much more convenient than a standard chuck and separate gauge in my opinion.As noted earlier, the one I have is about 30 years old and, even though it's well worn in places, it's still working fine. I did read some of the reviews before buying this since there were a few negatives and some people (very, very few) complained about inaccuracy compared to a digital gauge.My experience has also been that the gauge can get "off" by a pound or two over the years but they are easily calibrated by removing the end plug. A screwdriver and a reference gauge (like a digital or analog gauge that you trust completely) is all you need.Remove the end plug where the hose passes through the loop in the gauge body. Then remove the hard plastic inner washer and the rubber seal and slide the gauge cartridge out of the gauge body.Being reasonably mindful of the inner gauge window so you don't bend the little red line, remove the brass screw in the end of the cartridge and turn the split adjusting screw CW if the gauge is reading "high" or CCW if it's a little low. (All you're doing is adding or reducing tension on the spring that controls the gauge scale.)The adjustment screw is pretty sensitive so don't get carried away. A quarter turn will change the reading about 2 pounds on my 120 lb gauge. You may have to repeat the adjustment a couple of times to get it perfect but it really only takes a few minutes. I think I've re-calibrated mine about once every ten years (just did it recently since it had gotten off about 2 lbs) and it's never been off by more than a couple of pounds at 35 PSI.If your tires are regularly inflated to within a pound or two of the factory recommendation you're probably being more accurate than 90% of the other cars on the road.A final point on the gauge calibration is to be SURE the cartridge scale is aligned and visible in the outer gauge window when you reassemble it. There's nothing more to that than getting it turned right before putting the end plug and plastic washer back in the body of the gauge.I hope the calibration tip is helpful if you're worried about accuracy or if you have an old Milton inflator gauge that's off a little. The gauge itself is a simple, rugged, commercial design that will last a VERY LONG time if you're using it at home.

Built like a tank. Milton is quality and it shows. Easy to use, just press and hold the dual head to your tire stem and press the fill lever. This is not a locking chuck, so you will need to hold the head to the stem. The hose is plenty long and should reach dually tires. Due note that it is a bit heavy; don't accidentally swing the dual head into your vehicle! When I say it's built like a tank, I mean it.I wish the gauge on this inflator was a better range for passenger tires. 10PSI to 120 PSI is a very large range when all a passenger car needs is around 30PSI to 35PSI and maybe 60 PSI to 65 PSI for the spare. As such, I feel this inflator was designed more for trucks, hence the dual head design. Another thing to note is that the sight glass isn't the easiest to read, especially as I get older.My particular inflator gauge is accurate to around +/- 2 PSI. I tried to adjust it but I couldn't seem to make it much better. I still use a Accu-Gage H60X Professional Tire Pressure Gauge with Protective Rubber Guard (60 PSI) to verify the pressure after using this infiltrator. The Accu-gage is the same gauge the Car Talk guys recommend. If you want the made in the USA model, it's the Accu-Gage "M" Series - MH60X. The M Series is bigger, beefer, and cost a bit more. The Accu-gage of old used to all be made in the USA, but now only select models are.Don't get me wrong this works fine for cars, but if you are looking for precision measurements of the pressure, use a gauge that is calibrated for your pressure range. Remember that pressure gauges are most accurate in their middle region, so a 60 PSI gauge is best for passenger tires since you are most concerned about 30 to 35 PSI.

This tire inflator managed to accomplish precisely what I was seeking to do when I placed the order after having the air compressor delivered. I’m now able to completely avoid ever having to visit the gas station for a quick tire inflation.Just as what’s written on the tin — not a single opportunity to complain about anything related to the inflation device. Inflator features the ergonomic shape, pressure gauge readout for that fast confirmation of the number you’ve reached. It’s even sporting a satisfying heft to it giving you that impression of significance and durability.

It works. Seals well. Easy to position. Would buy another if I needed one.

I’ve had mine a couple years now and it’s worth the extra money for sure. I got tired of cheap over seas versions breaking on me, the Milton is well built and reliable.
