20 ft Engine water temperature gauge mechanical with alarm switch



This is the industry's best 20 ft mechanical water temperature gauge. With a 1/4" to 1/2" adapter, all of our 20 ft water temperature gauge are designed for heavy duty diesel engine application, such as Detroit Diesel, Cummins and more.
Each of our engine water temperature gauge comes with a black background, chrome rim, chrome needle and a temperature range of 0 to 250 degrees making temperature reading extremely easy.
One of the water temperature gauge feature that our customers like most it the fact that the capillary cable of the gauge comes covered with plastic. This prevents capillary or cable rust that are experienced by gauges of other brands, especially when it comes to marine applications.
When it comes to reliability, durability, and guarantee our mechanical heavy duty water temperature gauges always come on top.
