The thread adapters are pretty heavy, so I'm not worried about any pressure issues.
The 2" female & male adapters were just a little more. So, price wise these copper thread adapters are pretty cheap.
WOW, I sure got gouged on the price when I bought mine.
Mind you mine were 2.5" which are not as common. In Canada we are used to being gouged anyway.

When it come to soldering these, make sure you get them as shinny clean as you can. Use lots of flux. It will take a lot of heat to get the solder to flow all around evenly. A propane gas torch will work but I find MAPI gas works better. It burns much hotter. You dont want to overheat, use just enough to draw in the solder. After soldering, wipe off all the excess flux and clean it up as best is possible. Flux will cause the joint to corrode quickly and possably cause a leak. On my pool I noticed the original installer had painted all the joints as well to protect the solder.
