Watts 240935 Temperature Pressure Gauge 150 Psi 1/2 Mnpt

Product Description

The WATTS 240935 is a dual-function temperature and pressure gauge designed for monitoring both thermal and pressure conditions in a single instrument. It reads temperature in the range of 60 to 320 degrees F and handles pressure up to 150 psi. The gauge features a 1/2-inch MNPT back-mount brass stem, making it suited for inline or tank-mounted installations in plumbing, hydronic heating, and HVAC systems. Licensed plumbers and HVAC technicians install this type of instrument wherever simultaneous temperature and pressure readings are required at a single service point.

This gauge is a practical fit for residential and light commercial hydronic heating systems, boiler installations, water heaters, and pressure vessels where dual monitoring is required. The back-mount configuration allows clean panel or pipe installations where a flush or recessed gauge presentation is preferred. The brass stem construction offers corrosion resistance in typical potable and heating water applications.

Key Features

• Dual-function display: measures temperature and pressure simultaneously in one gauge
• Temperature range: 60 to 320 degrees F — suitable for hydronic and domestic hot water systems
• Pressure rating: 150 psi
• Connection: 1/2-inch MNPT back-mount fitting for inline or vessel installation
• Brass stem construction for durability in water and heating fluid service

Compatibility

Designed as an OEM-style replacement or direct-install temperature and pressure gauge for residential and light commercial boiler, water heater, and hydronic heating system applications requiring a 1/2-inch MNPT back-mount connection.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and allow the system to cool before removing any existing gauge or fitting. Apply appropriate thread sealant or PTFE tape to the MNPT threads before installing — do not overtighten, as brass fittings can be damaged by excessive torque. Verify that system operating pressure and temperature remain within the rated limits of this gauge after installation.
