Yes. Outpipe SR cable is safe for plastic pipes because of its self-regulating characteristics — the cable automatically reduces its output as the pipe temperature rises, preventing overheating that could warp or damage plastic pipe materials. Outpipe is compatible with both plastic and metal pipe types including PVC, CPVC, PEX, copper, and steel.

Outpipe bulk SR cable and MI fixed-length cable carry a 10-year manufacturer warranty. Pre-configured 120V kits carry a 5-year warranty. The difference comes from the kit’s added components — the factory termination and plug — which have a shorter rated service life than the heating cable itself. The cable in both formats is identical; the warranty difference reflects the additional hardware that makes the kit plug-and-play.

Yes. Outpipe is ETL listed for the United States and Canada across all three formats — bulk SR cable, MI fixed-length cable, and pre-configured 120V kits. ETL listing is issued by Intertek, an OSHA-recognized Nationally Recognized Testing Laboratory carrying equal legal standing to UL and CSA listings in the United States.

Outpipe and GutterMelt share the same fundamental cable construction and the same three formats — bulk SR cable, MI fixed-length cable, and pre-configured 120V kits. The difference is application. GutterMelt is designed for gutters, downspouts, and roof eaves. Outpipe is designed for pipes, valves, and tanks. Both are ETL listed for US and Canada, carry a 10-year warranty on bulk and MI cable and a 5-year warranty on pre-configured kits, and use the same self-regulating technology that prevents overheating on temperature-sensitive materials.

Outpipe is Heatizon’s heat trace cable for pipe freeze protection, pipe temperature maintenance, valve freeze protection, and tank heating. It is available in three formats. Bulk self-regulating (SR) cable is sold by the foot, cut to length in the field, and available in 120V, 208V, 240V, and 277V. MI (mineral-insulated) fixed-length cable is ordered to exact project length and delivers higher watt output for demanding commercial and industrial pipe heating applications. Pre-configured 120V kits come factory-terminated with a plug, ready to install, at 5 watts per foot in standard lengths from 5 to 100 linear feet. All three formats are ETL listed for the United States and Canada.
