For the entrance and exit fitting, I finally decided on the wires running straight out through a SS tee, and the water flow through the el portion of the tee. Where the wires came out the 1" tee, I bushed it and extended it with 1/2" for 2 more inches. Packed that exit point with epoxy putty and then inverted the tee and filled the exit point from the inside, through the future water flow point through the tee. That was a standard epoxy that flowed around the wires and filled the whole end of the tee. Be sure to wire brush and clean with acetone first. Pretty cheap and easy.
It works, and due to a flawed test switch, the pressure went up to about 175psi for quite some time, giving a severe test. A pressure relief valve kept it from going higher. The hard part was pulling the wire through the poly pipe - blew a pull rope through 300' with water using a home made foam plug- and then pulled the wire run. This was done to make a rugged canyon pipe and wire installation easier, but in terms of human BTU's expended, a seperate run of conduit down the hill might have been easier.
Restraint of the pipe became an issue because its a surface run. It wants to slide down the canyon.... Made some clamp blocks that grab the pipe O.D. and wired it to a few large oaks.
