BNTECHGO 14 Gauge Silicone Wire Spool 40 feet Ultra Flexible High Temp 200 degrees
Size: silicone wire red 20ft and black 20ft, Color: Red and Black
I'm reworking all the interior and exterior electrical wiring, relay's, connections (body grounds as well) on my 1994 GMC K-2500, the original wire did a good service for the 25 years it has been used. I'm disabled and refuse to pay $50,000 for a new truck (it wouldn't run as well as my 1994 anyway) I was hesitant about this brand or wire, but I thought (I'm not supposed to do that) I would give them a chance thanks to the reviews. I was Extremely Pleased at the High Quality of this "Real Copper" wire, not aluminum w/ coated- COPPER !, tinned very well, the silicone insulation is real industrial grade silicone. I run all my wire inside of braided nylon sheathing and securely fasten it every 24", using adhesive lined shrink tubing over all connections- works very well with this wire, it is easy to form for tight turns, lays straight once laid out, soders excellently (the top notch tinning helps there), I now have several hundred feet of 18, 16, 14 and 12 gauge of this VERY High Quality wire (It will be used on my solar system as well now) Thanks again Amazon for another "Top Quality, First Class" product that I can have delivered to my door, 90 miles from town, AND Thanks to everyone who takes the time to review the items we all could benefit from knowing better what the strong and weak points are

Solders nice, extremely flexible maybe too flexible
Size: silicone wire red 20ft and black 20ft, Color: Red and Black
The wire solders very nicely. It's very flexible, perhaps a little too flexible. I used this wire in a couple speaker building projects. I like to put the wire in a drill and twist the wires together, it's a nice look and helps with wire management. The too flexible part makes it so the wire doesn't stay tightly twisted. To remedy that I use heat shrink at either end to at least keep the wires somewhat together.

Quality, heat resistant silicone wire for my heating coil wine bottle cutting project. I didn’t need very much, but provided me the best price and option. No regrets.
