Description

DURAN® High Pressure Redline Tubular Gage Glass 1/2″ OD with wall thickness of 5/64″

Schott Duran® Redline Gage Glass – Redline Glass Code 7740. Borosilicate tubular gage glass has a red line between two white lines which, in the presence of a colorless liquid, magnifies the red line. The bold red line makes it easier to read the liquid level. Redline tubular gage glass is widely used in tanks, reservoirs and low pressure boiler applications.

Note: Each piece of Duran® tubular gage glass of standard length and in case quantities has the following identification imprinted on the glass.

****Glass can be cut to any desired length needed****
