Short Elbow Brass Liquid Level Gages feature a square shank with a pipe thread to screw into a tapped hole on the side of a reservoir.  The gage can be disassembled for installation in very tight places.  Short elbow gages are available with a 1/2" diameter glass sight as well as with a larger 5/8" diameter glass sight.  The leak proof construction, large vent hole and unrestricted passages permit fast and accurate liquid level response.
