Milton506 Original Service Station Tire Inflator and Air Pressure Gauge, Dual Head Chuck, 1/4" NPT, 15" Rubber Hose, 10-160 PSI

I recently purchased the Milton S-506 Tire Inflator and Air Pressure Gauge, and I am thoroughly impressed with its performance. This tool has everything you need to ensure your tires are properly inflated, and it’s incredibly easy to use. The dual head chuck makes it convenient for reaching all tire valves, even in tight spaces, and the 15" rubber hose gives me just the right amount of flexibility to move around my car or any other vehicles I need to work on.The pressure gauge is extremely accurate, which I really appreciate. It reads clearly and provides quick, precise measurements from 10-160 PSI, so you can easily adjust tire pressure to the exact level you need. I’ve found it to be spot-on compared to other gauges I’ve used in the past. The 1/4" NPT connector fits well with my air compressor, and the build quality feels solid and durable. It’s clear this tool was designed with long-term reliability in mind.

The Milton S-506 Original Service Station Tire Inflator and Air Pressure Gauge is the real deal. This isn’t some flimsy, plastic throwaway tool — it’s solid, well-built, and made from quality materials that feel like they’ll last a lifetime. As soon as you pick it up, you can tell it was designed with durability and performance in mind.One of my favorite features is the bubble window on the gauge. It not only makes it easy to read but also gives off a nostalgic 1950s-era vibe — like something you'd find in a classic service station. It adds a touch of retro charm to a very functional tool.Whether you're checking tire pressure or topping off air, this inflator works accurately. It feels professional and performs like something you'd see in an auto shop. I couldn’t be happier with it. Highly recommended for anyone who appreciates quality craftsmanship and wants a tool that just works.

This is a top-notch product. Works well and I should have bought this a long time ago. It works especially well on bicycles to fill and check the pressure without removing and losing air in the process.

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!

Milton should be the best. After a time the gauge started sticking. They replaced it. Good tool, well made, little expensive.

Very nice. I love how the air gauge is built into it. Reviews said that the gauge was not accurate, but I checked mine and it was dead on. There is a calibration that can be done to get the gauge accurate, but I wouldn't want to do it after reading how it's done unless I had to.

Awesome product. Reminds me of going to the service station when I was a kid. The service status used the exact same tire inflator.

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.
