ACR Copper Tubing

ACR copper tubing for refrigeration and air conditioning — Streamline and Mueller nitrogen-charged hard drawn straight lengths in 20 ft, and soft copper refrigeration coils in 35, 50 and 100 ft. Sizes run 1/8 in through 4-1/8 in OD, with wall thickness stated on every soft coil listing.

ACR tube is cleaned, capped and charged with nitrogen so the bore stays free of oxide before you braze it — that is what separates it from plumbing tube. Hard drawn lengths are for straight runs and rigid risers; soft coils bend by hand or with a lever bender for short connections and field-built line sets. Order by OD, not by nominal plumbing size.
