Any objections to running heavey copper lines with silver solder...It works great on refrigeration lines, lasts for years under great pressure and vibration....any objections

No politics allowed

from what im told... super brittle...


but i dont know jack

yeah...can harden with age and crack, I wouldn't risk it

It would probably work OK if you used bronze vibration isolators at each end of the lines, and refrigeration-quality tubing. The isolators are used in commercial systems to connect the compressor to the refrigerant lines and prevent work-hardening of the tubing. But after you add up all the costs you might be better off going with hoses and approved fittings.
