Fixture angle stop valve best strategy for copper?

marktmarkt Member Posts: 26
A while ago I went to repair a leaky compression angle stop on 1/2" copper. The copper pipe was messed up from people over-tightening, compression ring dinged pipe, etc. Now too short to cut off to get to clean pipe section. Tricky to sweat such a short pipe, cramped space, etc.. leaky stop valve ended up annoying multi-hour job.

I am about to trim out my own new house fixtures and wondering about the best approach. Thought about sweating on threaded fitting and using threaded angle stops.

Any thoughts on best approach, taking the long-term view?

    Brasscraft CS40 & CS41

    Brasscraft makes a stop with a 5" extension and bell escutcheon for sweating onto a 1/2" copper stubout. Rough it in with about a 6" stubout w/ cap. On finish just cut off the cap and slide the stop with extension over the copper to within an inch of the wall. Solder the extension and slide the bell escutcheon up to the wall. Very clean and neat. No exposed copper. The CS40 is an angle stop and the CS41 is straight.
