Disc and Ring Heaters | McMaster-Carr

These ETL-listed heaters keep containers warm in areas where hazardous material is present. Also known as heat blankets, they surround drums and totes to heat them up quickly.

Insulating Wrap-Around Heaters for
Diesel Exhaust Fluid (DEF) Totes

Extend the shelf life of your diesel exhaust fluid (DEF) while storing it in cold places.

Wrap-Around Heaters for Pails and Drums

Heaters are fiberglass-reinforced silicone rubber.

Heavy Duty Wrap-Around
Heaters for Pails and Drums

For applications requiring high heat over long periods of time, these aluminized steel heaters warm up faster and are more durable than silicone rubber heaters.

Adjustable-Diameter Wrap-Around
Heaters for Pails and Drums

Nonstandard-size containers are no problem—use the hook-and-loop closure to adjust these heaters to fit a range of diameters.

Insulating Wrap-Around Heaters for Gas Cylinders

Strap these heaters around cylinders to keep gas flowing when the temperature drops. Also known as heat blankets, they heat cylinders from the outside, safely warming liquefied gas enough so that it can vaporize.

Noncontact Wrap-Around
Heaters for Pails and Drums

To prevent hot spots that can damage heat-sensitive materials such as adhesives, sealants, and food, these heaters warm the air around containers without touching them.

Insulating Wrap-Around Heaters for Propane Tanks

Keep gas flowing even when the temperature drops—also known as heat blankets, these heaters wrap around propane tanks to safely warm liquefied gas so it can vaporize.

Bolt- and Clamp-Mount Heaters
for Plates, Molds, and Dies

Also known as strip and disc heaters, these bolt or clamp onto flat metal parts to heat the surface through direct contact.

Heaters for Extrusion- and Injection-Molding Barrels

Heat resins, raw materials, and food with these heaters that fit around extrusion and injection-molding barrels.

Heaters for Nozzles

Often used with extrusion, injection, and blow-molding machinery, these heaters clamp around nozzles to keep material warm for consistent discharge.

Insulating Wrap-Around Heaters for Pipe

Keep liquid in your pipes from freezing, maintain a specific viscosity, and prevent condensation in cold areas.

Insulating Wrap-Around Heaters for Hose

Keep the liquid inside your hose from freezing, maintain your liquid’s viscosity, and prevent condensation in chilly environments.
