Resideo by Honeywell TD-165 Tridicator Pressure Temperature Gauge 75 PSI 1/4" NPT

The Resideo by Honeywell TD-165 Tridicator is a combination pressure and temperature gauge designed for hydronic heating systems, boilers, and closed-loop applications. This dual-function instrument provides accurate monitoring of both system pressure and temperature through a single 1/4" NPT connection point.

Key Features:

• Pressure range: 0-75 PSI for monitoring system operating pressure
• Temperature range: 60-320°F for comprehensive system monitoring
• Long probe design for accurate temperature sensing in pipework
• 1/4" NPT male threaded connection for standard pipe fitting compatibility
• Easy-to-read dual dial display shows both parameters simultaneously
• Durable construction suitable for residential and light commercial applications

The TD-165 tridicator eliminates the need for separate pressure and temperature gauges, simplifying installation and reducing potential leak points. The long probe configuration ensures the temperature sensor extends into the fluid flow for accurate readings. Ideal for boiler systems, radiant heating loops, and other closed hydronic systems requiring simultaneous pressure and temperature monitoring.
