Heat Cable | McMaster-Carr

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.

Constant-Wattage Heaters
for Pipes and Tubes

These heaters require a separate temperature switch or controller to regulate heat output.

Ultra-Flexible Constant-Wattage
Heaters for Pipes and Tubes

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

Heavy Duty Constant-Wattage
Heaters for Pipes and Tubes

A durable copper cable cover protects these heaters from moisture, abrasion, and damage better than a plastic or rubber cable cover.

Ultra-High Temperature
Heaters for Pipes and Tubes

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

High-Temperature 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.

Ultra-Flexible Adhesive-Mount Heaters for Tanks

Ultra-Flexible Adhesive-Mount
Heaters for Tanks

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

Temperature and Humidity Monitoring

Thermocouple Wire

Make your own thermocouples.

Thermocouple Extension Wire

Designed to carry thermocouple signals over longer distances than standard thermocouple wire, this extension wire lengthens existing thermocouple connections.

Thermocouple Extension
Wire with Connectors

Extend the reach of your thermocouple probe—plug-in connectors on both ends of this wire speed up installation.

RTD Wire

Make custom RTD probes.

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.

Wire and Cable

High-Temperature Wire

Use this wire in ovens, furnaces, and other electrical heating equipment where temperatures reach 480° F and higher.

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.

High-Temperature Cable

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

Metal

Easy-to-Form Nickel Chromium Alloy

This nickel-chromium, often called Chromel C, provides effortless formability. Use it for heating elements, resistance windings, and hot-wire cutters.

Multipurpose 400 Nickel Wire

Bend this wire and it will stay in place. It is often used as safety lock wire.

High-Temperature 600 Nickel

Able to withstand temperatures up to 1000° F, 600 nickel is often used as safety lock wire in high-temperature applications. It is comparable to Inconel.

Corrosion-Resistant Tungsten Wire

This wire will spring back after bending. It's often used in heating and electrical applications.

High-Temperature Nickel-Clad Copper

This copper wire is clad in nickel to provide excellent corrosion resistance at temperatures up to 1200° F while maintaining high electrical conductivity.

Molybdenum Wire

Able to handle high melting points and conduct heat and electricity, this 99.95% pure molybdenum wire is often used in lights to create a support for filaments.

Tantalum Wire

Harder than platinum and able to withstand higher temperatures than gold, this 99.98% pure tantalum wire also resists corrosion and conducts heat. It’s often used in heating elements for furnaces.

Platinum Wire

Use this 99.95% pure platinum wire to create thermocouple probes and other parts that maintain high accuracy in extreme conditions.

Gold Wire

Used to make electrical connectors that are exposed to air and corrosive conditions, this 99.99% pure gold wire remains highly conductive where other conductors would fail.
