3/4 X 12 STANDARD GAGE GLASS

Standard Tubular Gauge Glass, 3/4 inch OD x 12 inch long is standard tubular gauge glass for liquid level indication, boiler gauge assemblies, tank level observation, process vessel sight gauges, and industrial MRO replacement. The listed attributes include a nominal OD of 3/4 inch, a length of 12 inch, a thickness or wall detail of 3/4 inch, giving buyers a straightforward way to match OD and length when replacing worn, broken, or clouded gauge glass. Tubular gauge glass is also searched as sight glass, boiler gauge glass, level gauge glass, borosilicate gauge glass, redline gauge glass, reflex gauge glass, heavy wall gauge glass, and standard gauge glass. This product copy uses the applicable style and material terms from the row so the item can be found by product type, size, and use case. Use nominal OD and length for customer-facing identification, and compare any actual dimension references when the assembly requires close fit. The actual OD reference of 0.75 inch (19.05 mm) gives an additional check point when close fit matters. Redline, reflex, heavy wall, plain, standard, and high-pressure wording is used only when supported by the product attributes. Review pressure, temperature, and fluid compatibility requirements before final selection.
