This removable propane tank gauge uses a very special yellow ink that when slightly heated will change color from yellow to orange.  Upon cooling, it will change back. There is nothing that gets used up or wears out. It will last for years.

Simply attach it to the side of your 20lb. tank as shown. All yellow indicates full, top half orange - bottom half yellow indicates half full, and all orange indicates it's time to fill your tank. Fits all R.V. and BBQ tanks. Easy to use, lasts for years, and will not fade in sunlight. Plus, it's American made.

Never find yourself having to run out in the middle of a BBQ and get yourself one of these handy gauges today!

Size: 1" wide.
