To waterproof the temperature probe a ½” copper pipe, two fitting copper caps, and a 7mm hex nut were purchased. A ¼” hole was drilled in the center of each cap end. One cap was held against a board for stability and four more holes were drilled perpendicular to the hole in the center of the cap end. The burrs from the drilling were cleared out with a 5/8” drill bit inserted into the cap and spun. A piece of ½” copper tubing was trimmed with a pipe cuter. The smooth factory edge of the copper pipe was left exposed while the sharp, freshly cut, end will be kept near the end cap instead of reaming the inside.

The temperature probe was pushed through the pipe. Silicone was applied to both sides of the hollow bolt to seal it and keep it stationary. The sealed probe was inserted into the holes of both caps, held end to end, so the single-hole cap could be attached to the pipe still covering the probe. The 7mm nut was attached on the five-hole cap side and tightened with a hex socket. The single-hole cap was filled with silicone, touching the edges and covering the probe, before being pushed onto the pipe. No solder was used but a lead-free solder could seal the copper to copper seals.
