1/4 in. refrigeration copper coupling with an internal stop, cup x cup. Solders two lengths of same-size ACR copper tube together; the stop centers the fitting so each tube bottoms evenly in the socket.
1/4 in. refrigeration copper 90 degree elbow, long radius, cup x cup. The long-radius sweep turns a refrigerant line 90 degrees with less flow restriction than a short-radius elbow.
3/8 in. refrigeration copper 45 degree elbow, long radius, cup x cup. Makes a 45 degree offset in a refrigerant line – typical on 3/8 in. liquid or small suction lines routing around framing.
1/2″ x 50′ soft copper refrigeration tubing. ACR (air conditioning/refrigeration) grade — clean, dehydrated, and capped. Use for suction lines and liquid lines.
7/8 in. refrigeration copper 45 degree elbow, long radius, cup x cup. Handles 45 degree offsets on large suction lines in commercial and higher-tonnage residential systems.
3/4 in. refrigeration copper 45 degree elbow, long radius, cup x cup. Used for 45 degree offsets on larger suction lines where a gentle turn is preferred over a hard 90. Sized by tube OD, the standard convention for ACR fittings.
3/4″ x 50′ soft copper refrigeration tubing. ACR grade — clean, dehydrated, and capped. Common suction line size for residential AC systems up to 3 tons.
Mini-split line set — 25 ft, 1/4″ liquid x 1/2″ suction, pre-flared ends. Insulated suction line. Ready to install on most 9,000-12,000 BTU ductless systems.
5/8″ x 50′ soft copper refrigeration tubing. ACR grade — clean, dehydrated, and capped. Common suction line size for smaller residential AC and mini-splits.
