Review on GPEH Solderless Through Splice Connector by Jay Huang

Following the gauge recommendations on this page, larger gauges have trouble fitting into the correct port. Using a 14 gauge blue wire connector, a metal welder will cut the wire in more than 50% of the connections. If you use these connectors, make a few test connections, then open the connectors again and check the wires. I hope you don't have my experience. I had to splice, solder and glue/set the pipes.
