About Heaters for Pipes and Tubes

Self-Regulating Heat Cable—Adjusts its heat output in response to surface as well as surrounding temperatures.

Constant-Wattage Heat Cable—Always puts out the designated amount of watts/ft., regardless of the surrounding temperature.

Constant-Wattage Heaters with Adjustable
Temperature Control for Pipes and Tubes

Turn the dial to control the percentage of time that these heaters cycle on, from 5% to 100%. Commonly used to thaw pipes, prevent valves from freezing, and heat beakers and flasks in labs, they're good for temporary and occasional use where rapid heating is required but precise temperature control is not.

Constant-Wattage Heaters with
Temperature Control for Pipes and Tubes

The thermostat automatically turns these heaters on when the temperature drops below 38° F and turns them off when the temperature reaches 45° F.

High-Temperature Constant-Wattage
Heaters for Pipes and Tubes

Rated for a maximum heat output of 900° F, these heaters are often used for thawing frozen pipes and rapid spot heating.

Cut-to-Length Constant-Wattage
Heaters for Pipes and Tubes

With a cable that supplies the same wattage along the entire length, these heaters remain consistent regardless of the surrounding temperature. All require a temperature switch or controller to regulate heat output.

Ultra-Flexible Constant-Wattage
Heaters for Pipes and Tubes

Wrap the flexible heating element around small-diameter pipes and tubes or pack it into tight spaces.

Self-Regulating Heaters for Pipes and Tubes

When the ambient temperature changes, these heaters automatically adjust the heat output along the length of their cable. Also known as self-regulating heat cable, they don’t require a separate temperature switch or controller.

Cut-to-Length Self-Regulating
Heaters for Pipes and Tubes

Also known as self-regulating heat cable, these heaters automatically adjust heat output at different points along their length to account for differences in environmental temperature.

Ultra-High Temperature Constant-Wattage
Heaters for Pipes and Tubes

For demanding applications such as hot-melt transfer pipes, these heaters have a maximum heat output of 1400° F.

Pipe Thawers

Thaw pipe without direct access to or knowing exactly where the frozen section is.

Ultra-Flexible Adhesive-Mount Heat Sheets

Also known as foil heaters, these bend around corners and edges without causing damage to the heating element.

Wire and Cable

High-Temperature Cable

For high-heat applications such as furnaces and ovens, this cable's insulation withstands temperatures of 390° F and higher.

High-Temperature Continuous-Flex Cable

Bend and flex this silicone-insulated cable in temperatures up to 350° F. It can keep moving in areas twice as hot as most other continuous-flex cables without degrading data or signal transmission.

High-Temperature Wire

Even at 480° F—hotter than some industrial ovens—this wire’s insulation won’t melt.

High-Temperature Wire Assortments

Keep several colors of high-temperature wire on hand with these assortments.

Low-Voltage High-Temperature Wire

Rated to 50 volts AC/DC, this wire is often used in small electronics and robotics. It withstands temperatures of 390° F and greater.

Roof and Gutter Heat Cable

Before ice begins to form, install this constant-wattage heat cable on roofs and in gutters and downspouts to prevent damage caused by ice buildup.
