Cut-to-Length Bulk Heat Trace Cables

Bulk heat trace cables are better for long pipe runs, custom layouts, or projects where fixed pre-assembled lengths do not fit. These are not plug-and-play products and require proper end sealing and power connection.

Important: Bulk heat trace cables are not ready-to-plug-in kits. They are better for installers, contractors, or users who understand electrical termination, waterproof end sealing, and proper pipe heat trace installation.

Pipe Heating Blankets

Heating blankets are useful when a round heating cable is harder to position. They combine wrap-style coverage with insulation, making them practical for valves, hydrants, elbows, outdoor faucets, short exposed sections, and other irregular areas.

Selection tip: Choose a heating blanket when the freeze-prone area is short, irregular, or difficult to wrap with standard round heat tape. For dry or empty pipe conditions, the self-regulating blanket is usually the safer fit.

12V External Pipe Heating Cable

The 12V heating cable is a low-voltage external pipe wrapping option for applications where a standard 120V outlet is not available.

External Heating, Simple Freeze Protection

How External Pipe Heating Cables Work

External heating protects exposed pipes from the outside. Match the cable, control method and insulation to your installation.

Apply heat outside the pipe. Choose a cable or blanket designed for the pipe or fitting you need to protect.

Keep the heat in. Use suitable pipe insulation over the heating cable as directed by the product instructions.

Choose the right control. A thermostat switches power on and off. Self-regulating cable adjusts heat output but does not switch itself off.

Match the installation. Choose plug-in, cut-to-length, heating blanket or 12V options for your application and power supply.

Choose based on your installation type. For common home water pipes, a plug-and-play 120V pipe heat tape is usually the easiest choice. For long or custom pipe runs, choose a cut-to-length bulk heat trace cable. For valves, hydrants, outdoor faucets, elbows, or irregular areas, a pipe heating blanket may be easier to wrap. For RVs, boats, or low-voltage systems, choose a 12V self-regulating heating cable.

PPG-B and PPG-D include a built-in thermostat for automatic ON/OFF control. PPG-D adds separate indicators for power and heating status. PPG-Y has no built-in thermostat and heats whenever it is powered. Choose the model that matches how you want to control and monitor your pipe heating.

No. Bulk heat trace cables are cut-to-length products and require proper end sealing, power connection, and installation. They are better suited for installers, contractors, or users with electrical installation experience. If you want a ready-to-use option, choose a pre-assembled plug-and-play pipe heat tape.

Choose a pipe heating blanket when the freeze-prone area is short, irregular, or hard to wrap with a standard round cable. Heating blankets are useful for valves, hydrants, outdoor faucets, elbows, large fittings, and short exposed sections. They combine heat and insulation in a wrap-style design.

No. External pipe heating cables are designed to be installed on the outside of the pipe only. They should not be inserted into water lines or used for internal immersion. For inside-the-pipe applications, use a dedicated in-pipe heating cable designed for that purpose.

Yes, pipe insulation is recommended in many outdoor or exposed applications. Insulation helps hold the heat around the pipe, improves freeze protection, and can reduce heat loss. Always install the heating cable and insulation according to the product instructions.
