Ametek 132509 Process Pressure Gauge 0-60 Psi 6 in Lower Mount

Product Description

The AMETEK 132509 is an analog process pressure gauge designed for continuous system pressure monitoring in HVAC, plumbing, and industrial piping applications. It features a 6-inch dial face with a 0 to 60 psi range and delivers 0.5% of scale accuracy, making it a reliable choice where precise pressure readings are required. The thermoplastic case resists corrosion in typical mechanical room environments, while brass wetted parts provide compatibility with water, air, and many common process media. The lower-mount NPT connection allows direct in-line or manifold installation. Licensed plumbers, HVAC technicians, and pipefitters are the typical installers for this class of gauge.

The AMETEK 132509 is suited for residential and light commercial mechanical systems including hydronic heating loops, domestic water supply lines, compressed air headers, and chilled water circuits. The 6-inch dial improves readability at a distance, which is useful in boiler rooms and equipment spaces where gauges are mounted at height or behind other components. The lower-mount configuration positions the connection at the bottom of the case for vertical riser or tee installations. No compatible model numbers or system families are specified in the product data beyond the Series 1931 designation and Model 1901.

Key Features

• 6-inch analog dial for high-visibility pressure readings
• 0 to 60 psi range with 0.5% of scale accuracy
• Lower-mount 1/2-inch NPT connection for in-line or tee installation
• Brass wetted parts compatible with water, air, and common process fluids
• Thermoplastic case construction for corrosion resistance
• Dry gauge — no liquid fill — simplifies service and disposal

Compatibility

Designed as an OEM-style process gauge for hydronic, compressed air, domestic water, and general piping systems requiring a 1/2-inch NPT lower-mount connection and a 0 to 60 psi measurement range.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local mechanical codes. Isolate and depressurize the system fully before removing any existing gauge or fitting the new one. Apply thread sealant or PTFE tape to the NPT threads — do not overtighten, as thermoplastic-case gauges can crack if excessive torque is applied to the case body. After pressurizing, inspect the connection for leaks before returning the system to service.
