Your cart is empty. The 20T-250-4-1/2 is a 2" Temperature Swichgage.
This very popular design features a diaphragm-actuated, temperature-indicating gage, with a built-in electrical switch for tripping alarms and/or shutdown devices.
This model has a 4-foot capillary length with a standard 1/2-14 NPT threading, and a temperature range from 130-250øF (54-121øC).
The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. This vapor actuated gage features a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading.
Inside the 20T-250-4-1/2, the gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact.
Contact(s) are grounded through the Swichgage case. This gage has a self-cleaning motion to enhance electrical continuity.

Working. We used it to replace the same model that had broken when we were doing an engine rebuild. This one has moisture in it. Watch the PRICE. I am seeing the price has gone UP shortly after I purchased.
