These thermometers have a 1/2 inch male NPT thread, a 3 inch temperature dial and come with either a 3 or a 6 inch long probe which makes it perfect for a mash tun to monitor mash temperatures or for your kettle to monitor your wort as it comes to the boil. These thermometers are designed to be used with couplers or an existing port on your tun or kettle.
Don't have a port? Select the weldless thermometer kit option to get the additional high temperature, food grade, silicone o-rings and stainless steel backing nut. All you need to do to install is drill or punch a 1 inch hole into your vessel.
