Someone must have done this before, but I can't find it. My Rubbermaid HLT will have a vertical element in the middle and 1/2" OD SS 50 ft tubing coil around it for recirculating the wort from the MLT and also for cooling the wort from the BK. Most of this comes from The Pol, but his coil ends went thru the lid and I want mine to come out high and low through the side of the cooler. It seems like I'd be able to drain the coil that way - and freezing pipes are a real problem around here in the winter. So - how do I make a weldless connection that just pops thru the side and then seals securely? I'd like to be able to disassemble it a couple of times a year for cleaning. Maybe use the Bargain Fittings bulkhead with the tube soldered inside a nipple and a locknut with trapped silicon o-ring on both sides?
