dresser coupling on wet return?

jpf321jpf321 Member Posts: 1,562
Rather than figure out how to thread the return at the floor, I'm considering using 2 "dresser universal 90" couplings on a section of my 1-1/4" wet return (for a year or so, until I can repipe and upgrade) ...does anyone have any comments regarding their use? are the "universal type 90" rated for the wet return temps? the dresser website is down so I can't get to the specs right now.
