Thermocouple Connection Heads

 

Screw cover with chain | Flip Top | Miniature

The Thermocouple Connection Head is an important component in the construction of an accurate thermocouple system. The head is used to house the thermocouple terminal block which connects the thermocouple element to the extension wire. The thermocouple connection heads function is two fold, to protect the electrical connections from contamination from the elements and maintain a constant temperature surrounding all internal connections.

Thermocouple Connections heads are available in a variety of materials and NPT process thread configurations. We stock heads in Aluminum, Cast Iron, Stainless Steel, Polypropylene, Delrin, Nylon, Brass, and Nickel Plated Steel.
