## Description

Milton (#506) Original Dual Head Chuck Tire Inflator Gauge - 15" HoseMilton Industries specializes in tire inflator gauges and this original S-506 dual chuck inflator gauge was the first gauge of its kind ever built in the industry. We were also the very first in the industry to offer replacement cartridges! Gauge and valve cartridges are both replaceable. This essential pneumatic tool is ideal for any vehicle trunk, home garage, or automotive shop. Dual head chuck inflator gauge is made of heavy duty construction which provides for long life, even under extreme use and conditions. Equipped with magnifying lens for full view of scale. 1/4" NPT air inlet.USES: Auto, sport utility, truck, bicycle, motorsport, trailers, motor homes/5th wheels, wheelbarrows, golf carts, lawn tractors, motorcycles, ATVs, and more.PRODUCT SPECIFICATIONS: PSI: 10-160Increments: 2 lb.* kPa: 80-840 (available via special order)Increments: 20 kPaThreads: ⅜-241/4" NPT air inletINSTRUCTIONS FOR USE:If using a dual head type tire chuck with an inflator gauge and notice air is escaping through the off-side once connected to the tire’s Schrader valve, simply release the trigger and remove the inflator from the Schrader/tire valve. Point the straight side of the outlet up into the air (make sure it’s not pointed at someone). Squeeze trigger, allow air to flow (gravity will cause the sealing valve to drop), and place the chuck end onto the Schrader/tire valve while air is still flowing. Air will start to flow into the tire.Dual head type tire chucks are unable to inflate a completely flat (zero air pressure) tire. Tire air pressure would normally cause the sealing valve to move and seal the unused side of the chuck. However, if a tire has 0 air pressure, the self-sealing valve has no pressure to react to.DRIVE SAFELY: Maintaining proper tire pressures improves vehicle handling, reduces risk of tire failure, improves fuel economy, and increases the life of your tires.

## Questions & Answers

**Q: Has anyone verified the accuracy of the gauge?**
A: It's close when it's new but it will lose calibration. From Roy's review: "To adjust this gauge, take the big screw off of the end, and then pry out the plastic discs with the little holes in the center. Now slide the cartridge out. Take the big screw off the end of the cartridge, and use a little screwdriver to adjust the gauge. 1/2 turn = about 5 psi at the low (30-40 lb) end of the scale. A little trial and error checking against a gauge you trust at the pressures you’re checking... and you’re done."

It definitely helped me, I just calibrated mine and it's dead on. I'll add that you want to turn the screw clockwise to decrease and counterclockwise to increase the reading.

**Q: how do you switch from straight to angled head?**
A: You don't. The angled head is for checking a truck dual when the valve stem is  facing  away from you. You go behind it with the angle head and pull it toward you.

**Q: Can any sort of Presta adapter be used with this inflator?**
A: Yes, I use it on Presta & Schrader valves on my bicycle tires.

**Q: Has anyone used this with a  presta adapter?**
A: this is an automotive style so it has a schrader valve fitting. Look for a presta valve adapter. They are cheap, buy two they're small so you're going to lose it. Other than specialty bike supplies nothing comes ready to use with a presta valve.
