CARBO Instruments Compound Pressure Gauge -30 inHg to 160 PSI, Liquid Filled, 2.5" Dial, 1/4 NPT Lower Mount, 304 Stainless Steel Case, Brass Wetted Parts, Dual Scale PSI/inHg - ASME B40.1 Grade A

CARBO Instruments Compound Pressure Gauge -30 inHg to 160 PSI, Liquid Filled, 2.5" Dial, 1/4 NPT Lower Mount, 304 Stainless Steel Case, Brass Wetted Parts, Dual Scale PSI/inHg - ASME B40.1 Grade A

• ASME B40.1 Grade A Accuracy (+/-2-1-2%): Professionally manufactured for reliable performance; large 2-1/2" (63mm) dial with high-contrast markings ensures easy pressure reading.
• Liquid Filled for Stable Reading: Glycerin filling stabilizes pointer movement and dampens vibration and pulsation to prevent needle flutter and pressure spikes, ensuring accurate dual-scale PSI/Bar readings.
• Industrial & Commercial Use: Ideal for air, oil, water, and gas systems including pumps, compressors, hydraulic presses, pneumatic equipment, irrigation, HVAC, pool filtration, and general machinery.
• Heavy Duty Construction: Rust-resistant 304 stainless steel case with durable brass wetted parts and copper alloy internals; chrome-plated brass connection and polycarbonate lens for impact resistance.
• Standard 1/4" NPT Lower Connection: Ensures compatibility with most regulators, tanks, manifolds, and fittings. Please verify your connection size before ordering.
