It’s a common question that the GlowCap™ End Seal Kit was designed to answer from a distance. If the green indicator light is on, your cable is working. Installing the GlowCap™ End Seal kit on self-regulating heat cable takes about five minutes total. The kit includes a 12” section of 6 watt HeatTapePro™ Self-Regulating Heat Cable that is factory terminated with a GlowCap™, which is an injection molded body with an embedded 100,000 hour UL-Listed LED. The other end of the assembly is prepared and ready to be crimped onto the stripped end of any 10-13mm self-regulating heat cable.
The GC-ESK increases system reliability significantly because cable function can be verified in seconds with a quick glance at the GlowCap™. This is particularly helpful on cable systems that are inaccessible, such as on high locations
“Heat Tape Pro did exactly what I needed it to do. Now I don’t have to worry about water leaking into my house, because I can tell when it’s working by the little light on the end of the cable.”

The GlowCap End Seal Kit (GC-ESK) is a simple way to know your cable is working. Why does this matter? If you circuit breaker trips for some reason, you could possibly get a massive ice dam before you realize your heat cable isn't working. The GlowCap allows you to see at a glance that everything is OK. It’s a field-installed termination kit that lets you add our signature LED indicator light to any self-regulating heat cable between 11-13mm wide. It includes a 12" section of our 6-watt HeatTape Pro with a factory-installed GlowCap™ that you join to the end of your field-installed 120v or 240v Heat Tape Pro cable.
Yes, as long as the cable is self-regulating and measures between 11-13mm wide. The kit is designed to work with most standard self-regulating heat cables, not just our Heat Tape Pro. However, we obviously can't guarantee compatibility with every cable on the market, so measure your cable width first.
Installation takes about 5 minutes total and is pretty straightforward. You'll need basic electrical tools to strip the self-regulating heat cable end, shrink on some heat shrink tubing and then crimp the butt splices. The kit comes with everything you need for the termination itself and we include detailed instructions.
The LED is rated for 100,000 hours of operation and is UL-listed for reliability. At typical seasonal use (let's say 4 months per year, 24/7), that's over 50 years of operation.
Absolutely. The GC-ESK GlowCap End Seal Kit works with both 120V and 240V self-regulating heating cables. The LED indicator will function properly regardless of the voltage, so you don't need different kits for different systems.
The biggest advantage is peace of mind, especially for cables in hard-to-reach places like high on your roof. Instead of having to climb up and feel the cable to see if it's warm, you can just look for the green light from the ground. It's also great for troubleshooting. If the light's not on, you know there's a power issue somewhere in your system.
The GlowCap is pretty durable, but if it gets damaged, you can replace just the GlowCap portion without redoing your entire heat cable installation. The kit is designed so the LED indicator is the only part exposed to the elements and it's built to handle tough winters.
You typically only need one per cable run since each cable should only have one termination point. However, if you have a really long run or want monitoring at multiple points, you could potentially splice in additional kits. Just make sure you maintain proper electrical connections and don't exceed the cable's amperage limits.
Yes, the GlowCap End Seal Kit can be attached to any field installed self-regulating heat cable providing it meets the parameters outlined above. The LED simply indicates when power is flowing through the cable.
For most people, absolutely. At $22.95 (price may change), you're getting instant visual confirmation that your system is working, which can save you from expensive ice dam damage if there's ever a problem. Plus, it eliminates the guesswork and the need to physically check your cables. Think of it as cheap insurance.

PipeFreezePRO comes with one or more 30ft rolls of high-quality fiberglass tape, but you can use any tape with a temperature rating of 150º F and above. Self-adhesive aluminum foil tape can be used but avoid standard tapes, including electrical tape and duct tape because they lose their adhesion when exposed to heat. Remember, it’s imperative to cover the pipe/heat tape assembly with pipe insulation (1/2″ minimum thickness). Think four easy steps: 1) cable on pipe, 2) tape on cable, 3) insulation on pipe/cable and 4) tape on insulation.
Pipe Freeze PRO can be overlapped during installation. This is a fundamental advantage of self-regulating heat cable over cheap, constant wattage cable found in hardware stores is that it can be overlapped without risk of shorting out or catching fire. So yes, overlap away!
The amount of heat cable needed for pipe freeze prevention is determined by a couple of simple factors including: Length of pipe, diameter of pipe, distance to power supply and number of valves.
Most of the time, we do not recommend a spiral cable application because it’s simply not necessary. It requires 3x the cable to do the same job.
Therefore, simply use a straight, single run of cable affixed to the bottom of the pipe (think 6 o’clock position) using the provided fiberglass installation tape. Next, add 1 foot of cable for every valve because you will be wrapping the valve with cable. For pipes less than 1″ in diameter, a single cable run is sufficient. For larger pipes, two cable runs are recommended. Keep in mind that plastic pipes are less thermally conductive so you may choose to use two cable runs on larger plastic pipes to be safe. Finally, if your outlet isn’t close to the pipe you are treating, factor in enough heat cable to reach your outlet (Pipe Freeze PRO does come with a 36″ power cord).
Finally, you must install insulation on your pipe and heat cable assembly in order for the system to operate effectively. See instructions for further details.
The cable can be exposed to wetness but the thermostat must stay dry to function properly. Use Pipe Freeze PRO for pipe freeze prevention applications only.
Consider using Heat Tape Pro inside of open drain pipes as that cable is rated for use in wet areas.

Pipe Freeze Pro’s integrated thermostat turns power on and off automatically to the cable to save electricity. The thermostat is the lump located between the power cord and the heat cable. The thermostat triggers the cable to turn on at 37ºF and off at 50ºF, with a sensitivity range of +/- 4ºF. It’s a great feature that makes Pipe Freeze Pro unique among heat cables on the market.
Yes and no. The cable is approved for exposure to wet conditions but you should keep the thermostat dry for proper operation.
No. The thermostat need only be exposed to cold air. It does not hurt to have the thermostat attached to the pipe but it is not necessary. If you choose to attach it to the pipe keep in mind that the thermostat should not be covered with insulation.
No. You want the thermostat to react to the cold environment so it triggers the Pipe Freeze Pro to turn on.
Every Length of Heat Tape Pro has a cord length of 10-feet that is not included in the listed/state length. Meaning: A 100-foot Heat Tape pro will have a 100 feet of heated cable + a 10-foot unheated power cord.
Every Length of Pipe Freeze Pro has a cord length of 3-feet (36″) that is not included in the listed/state length. Meaning: A 30-foot Heat Tape pro will have a 30 feet of heated cable + a 3-foot unheated power cord.
