Glass-Trac Liquid Level Gages and Valves

Reflex Gages

Glass-Trac Reflex Gages use prism glass to provide an excellent indication of the liquid level. All liquids appear black in high contrast to the mirror-like surface above. This clean line of separation can be sighted from many yards away. Reflex Gages are made in three pressures series (maximum 4000 psig @ 100ºF) and are tapped for ½” or ¾” NPT connections. The standard Glass-Trac level gages are designed for minimum -20ºF service.

On Glass-Trac Reflex Close Hook-up Gages with ½” NPT connections, the center-to-center dimensions is the same as the overall length on standard gages.

On Close Hook-up Gages with ¾” NPT connections, the center-to-center dimensions is the same as the overall length on standard gages plus ⅜”.

Reflex Gage Materials / Pressure Ratings
BODY (LIQUID CHAMBER)	Accurately machined from square tubes to provide perfect seating for gage glasses. Glass is recessed for protection. Body materials include 316 stainless steel and carbon steel.
COVER	Glass-Trac gage covers are made of carbon steel or 316 stainless steel in all their sizes and pressure ratings for higher strength and dependable service. All covers are machined to provide recessed seating protection for the glass.
GLASS	All standard Glass-Trac Reflex Gages use tempered borosilicate glass in nine standard lengths. Each glass has expertly molded reflecting prisms.
GASKETS & CUSHONS	High grade non-asbestos is used in gaskets and cushions for Glass-Trac gages. The machined recess in the gage body and cover protects the gasket and cushion as well as the glass.
BOLTS	Glass-Trac gage bolts are made of alloy steel, ASTM A-193 Grade B7.
NUTS	Gage nuts are made of steel, ASTM A-194 Grade 2H.
