Review on Lifegard Aquatics Double Threaded Bulkhead: Enhanced Hydraulics, Pneumatics & Plumbing Solutions by Chris Litton

. They worked great even though the bulkhead bolt + bushing cost more than the barrel itself! (By the way, here's the secret to how this works if you have a barrel with two bait holes and don't want to cut off the entire top to get at the assembly: Thread a line through one of the holes on the barrel, pull through that just drilled hole at the bottom and then slide the bulkhead along the cord down to the hole). A small silicone bead in addition to the supplied rubber seal ensures 100% water tightness. The lead-free brass garden hose end threads perfectly into the outer end of this piece.
