Well it can be done but boy it can be tricky,i changed a pump a few years back in a tight position and had the cut round the joint and along and pull bits of one bit at a time and then sand it all flat again so the new fitting could be fixed :shock:

Is it possible to cut it out further along and put in a coupler :idea:

The easiest way IMHO would be to take said fitting to a machine shop, ask them to turn it so that they cut out inside to original diameter........ I've haven't done this myself, but it would work.
Even if they turned it so that fitting was slightly slack by a few thou, you could just put plently of glue on and I'm sure it would seal......only trouble is finding a machine shop, or do you know a friend of a friend who works in such a place........alternatively, get a rubber boot connector, they work great. :wink:

Other than in the larger sizes, most true-union valves come with two connector sets, one for glue joints and another with threaded connectors. I just use the threaded connector so I can change configurations many times and still use the valve. With larger sizes you must purchase the type of thread you will be using. No problem If I end up with threaded, but I must convert the connector to work with a threaded coupling if I may want to salvage an expensive valve. I glue a slp female x threaded converter female to the valve (threaded female so abuse isn't likely to damage the threads.) And that valve is always suitable to salvage
