Our stock band heaters with diameters 4 inches and up are built with two-piece construction. Two-piece band heaters can open up to fit around larger-diameter pieces, and are secured into place by clamping.

If none of these band heaters is right for your application, you can configure your own band heater in any size, get an instant quote, and order online. If you have any questions about stock or built-to-order band heaters, please send us an e-mail, fill out one of our contact forms, or give us a call at (866) 685-4443.

Stock band heaters usually ship within 3-4 business days after an order is placed.


The maximum watt density (W/in²) that should be used is determined by the maximum temperature to be attained. Processes that involve a higher temperature call for a heater with lower watt density, so as to maintain longer product life. Excessive watt density stresses heaters and causes them to burn out. Follow the guidelines below for the longest service life from a band heater:
Operating temperature Max. watt density
300°F 40 W/in²
400°F 30 W/in²
500°F 21 W/in²
600°F 12 W/in²
700 to 900°F 10 W/in²
