Ametek 132551 Pressure Gauge 6 Inch 0-300 Psi Lower Back Mount

Product Description

The AMETEK 132551 is an analog pressure gauge designed for accurate pressure measurement in HVAC, plumbing, and industrial service applications. It features a 6-inch thermoplastic dial face with a 0 to 300 psi range and a rated accuracy of 0.5 percent of scale, making it suitable for applications where reliable, at-a-glance readings are required. The lower back mount configuration with a 1/2-inch thread connection allows for clean panel or pipe installation with the port exiting from the rear lower position. Licensed mechanical contractors and service technicians are the typical installers for this gauge.

This gauge is appropriate for residential and light commercial systems where a large, readable dial and moderate pressure range are needed. Typical applications include pressure monitoring on water supply lines, hydronic heating systems, compressed air circuits, and general HVAC service work. The thermoplastic case keeps weight low and provides adequate protection in light-duty environments. The analog dial design eliminates the need for any power source, making it straightforward to install in a wide range of field conditions.

Key Features

• 6-inch analog dial for easy reading at a distance
• 0 to 300 psi pressure range suits common HVAC and plumbing applications
• 0.5 percent of scale accuracy for reliable field measurements
• Lower back mount with 1/2-inch thread connection for clean rear-exit piping
• Thermoplastic case construction reduces overall weight
• No external power required — fully mechanical analog operation

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and light commercial HVAC, plumbing, and compressed air systems requiring a 6-inch lower back mount analog gauge with a 1/2-inch threaded connection.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Shut off and relieve system pressure completely before removing an existing gauge or making any threaded connections. Apply an appropriate thread sealant or PTFE tape to the 1/2-inch male threads before installation, and tighten to a firm seat without over-torquing the thermoplastic case. Verify that the system pressure range does not exceed the 300 psi maximum rating of this gauge.
