Befuddled and getting different answers depending on who I ask...
I have a swamp (evaporative) cooler that has been running for several years on 1/4" clear plastic tubing. Unfortunately, this means changing the tubing every season. Second floor application and I don't like ladders. So I decided to go with copper tubing to within a foot or so of the faucet and then switch to plastic. Replace the foot or so of plastic every year.
The local hardware store folk insist, sometimes, that a compression fitting will work if you apply enough torque. Could be true. I sacrificed about 6" of tubing and tried it. My result was that while the donut would hold the tubing in place I doubt that it would be water tight. Donut spins a bit. Applying larger amounts of torque inside the swamp cooler seems risky to me.
So the next thought was to use flare joints for the copper tubing. This means finding a compression thread to flare thread adapter (coupler), a nipple to get outside of the cooler, and another flare coupler to attach the tubing to.
Any ideas?
Thanks in advance.
