Priced at $14.40, this is the bottom-mount companion to the G251430B — the largest dial in the Cast Air gauge family, with a high-pressure 300 PSI range, in a bottom-mount configuration for upright installation off horizontal fittings.\u003c\/p\u003e\n\u003cp\u003eThe 2.5-inch dial on this gauge is noticeably larger and more readable than the 2-inch gauges in the lineup — a meaningful practical difference in compressor rooms, mechanical rooms, or anywhere the gauge is mounted at head height or above. The bottom-mount port means it threads into a horizontal port and stands upright, dial facing the operator.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1\/4 inch NPT connection\u003c\/strong\u003e — fits standard compressor tank ports, manifold taps, and pressure switch ports\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBottom-mount configuration\u003c\/strong\u003e — port exits from the base; gauge stands upright off horizontal fittings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5-inch dial\u003c\/strong\u003e — the largest dial in the Cast Air gauge series for maximum readability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e0-300 PSI range\u003c\/strong\u003e — covers high-pressure compressor systems and standard shop air with wide margin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGenuine Cast Air replacement component\u003c\/strong\u003e — replacement specification for Cast Air compressor and system applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e G251430U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount:\u003c\/strong\u003e Bottom mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Size:\u003c\/strong\u003e 2.5 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange:\u003c\/strong\u003e 0-300 PSI\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChoosing the Right Gauge From Cast Air Gauge Lineup\u003c\/h3\u003e\n\u003cp\u003eCast Air offers pressure gauges in three dial sizes (1.5 in., 2 in., 2.5 in.), two mount types (back, bottom), and multiple ranges (0-60, 0-160, 0-200, 0-300 PSI). The G251430U is the largest, highest-pressure bottom-mount option. Use this gauge when you need the combination of maximum readability and high-pressure range, in a bottom-mount configuration. If back-mount fits your installation better, use the G251430B. If you are on a standard 150 PSI system and the 0-300 PSI range is more than you need, the G201420U (0-200 PSI, 2 in. dial) is an alternative.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-pressure compressor tank gauge replacement\u003c\/li\u003e\n  \u003cli\u003eLarge-format pressure indicator on compressed air mains\u003c\/li\u003e\n  \u003cli\u003ePanel and manifold installations requiring maximum readability\u003c\/li\u003e\n  \u003cli\u003eTwo-stage and high-pressure industrial compressor systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Buy From OEM Diagnostic Tools?\u003c\/h3\u003e\n\u003cp\u003eWe have been supplying compressed air components since 2016.
