20T-220-10-1/2 Murphy Temperature Switchgauge

The 20T-220-10-1/2 is a 2" Murphy Temperature Swichgage® designed to monitor engine and equipment temperatures in heavy-duty applications. This diaphragm-actuated, temperature-indicating gage features a built-in electrical switch for tripping alarms and/or shutdown devices, helping protect engines from overheating.

With a 10.5-foot capillary length and standard 1/2-14 NPT threading, it's ideal for installations where the gage must be remotely mounted. The gage pointer serves as both a temperature indicator and a switch pole, completing a circuit when it reaches the adjustable limit contact — a proven design used across oil field, marine, construction, and trucking industries.
