*A3 PLAIN GA. GLASS

This gauge glass is supplied in Plain, catalogued under part number 4MPL3. It seats in a gauge frame to give a protected, direct view of process level.

The material holds up against internal pressure, chemical attack from water and steam, and thermal shock. That behavior comes from the compound itself: Borosilicate gauge glass is specified for clear, direct visual indication of liquid level and annealed for consistent strength.

Common environments for this compound include process tanks and vessels, water treatment, and boilers and steam drums.

Stocked as 4MPL3 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
