Since I can't find any interest in the welding route, I'm offering these up for sale or trade. I'd be happy to trade all 3 of these for 2 threaded 1/2" three-piece SS valves, or I can sell them for $12 each + shipping.
I recently bought some three-piece 1/2" ball valves off eBay. To my dismay, they turned out to be socket-weld, not threaded, despite my confirmation that they were threaded prior to purchase (see here
Is there anybody here that'd be able to weld threaded fittings (or possible tri-clovers or camlocks) onto these for me? I don't trust my family-friend welder to do the job properly or quickly (or even comprehend what I need to have done).
Alternately, I'd like to trade these 3 socket-weld three-piece valves for 2 threaded three-piece valves. Any takers?
