Slime 2020-A Dually RV Gauge (10-160 PSI)

The bleed button on this gauge is quite useful. I can slowly released air from the tires by holding down the bleed button while the tire pressure is being measured. I find it easier to overinflate the tire just slightly, by a pound or so, and release the excess using the bleed valve to obtain the wanted pressure. The dial on the gauge also retains the tire pressure reading after measuring, the hose is ~5" long and quite flexible to fit in some hard to reach spots.

So, excellent price on this...but with the low price comes a smell that is awful. The black rubber surroundind the gauge has an odor that will not go away. So if you can deal the the odor, great product...but i will be buying a different one.
