Glass-Trac Transparent Gages

Glass-Trac Transparent Gages use 2clear, see- through glass on both sides so that both the color and the interface of liquids can be viewed. Electric lighted gage illuminators are available for use on Transparent Gages and provide easy viewing of liquid levels in dimly lighted areas. Transparent Gages are made in three pressure series (maximum 3000 psig @ 100ºF) and are tapped for ½” or ¾” NPT connections. The standard Glass- Trac level gages are designed for -20ºF service.

On Glass-Trac Transparent Close Hook-up Gages with ½” NPT connections, the center-to- center dimension 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”.

MATERIALS  
BODY (LIQUID CHAMBER): Accurately machined from square tubes to provide perfect seating for gasket, and gage glasses. Both glasses are recessed for protection. Body materials include Type 316 stainless steel and carbon steel.
COVERS: Both covers on transparent gages are carefully machined to provide perfect seating for cushions and gage glasses. This machining also provides deep recessed seating in the cover for added glass protection. Covers are available in Type 316 stainless steel and in carbon steel.
GLASS: All standard Glass-Trac Transparent Gages use tempered borosilicate glass in nine standard lengths. Each transparent glass is crystal clear and has the highest strength possible.
GASKET & CUSHIONS: 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.
(Torque instructions for gage bolts are on Back Cover.)
