| OD (Inches) | OD (Millimeters) | Common Use |
| 1/8" | 3.18 mm | Capillary lines, small refrigeration |
| 3/16" | 4.76 mm | Control lines, low-capacity systems |
| 1/4" | 6.35 mm | Residential HVAC systems, inlet/outlet |
| 5/16" | 7.94 mm | Mini-split units, refrigerant lines |
| 3/8" | 9.52 mm | Medium capacity cooling lines |
| 1/2" | 12.7 mm | Common in split systems |
| 5/8" | 15.88 mm | Suction lines, HVAC installations |
| 3/4" | 19.05 mm | Commercial A/C units |
| 7/8" | 22.23 mm | Larger suction lines |
| 1-1/8" | 28.58 mm | High-capacity refrigerant systems |
| 1-3/8" | 34.93 mm | Industrial chillers |
| 1-5/8" | 41.28 mm | Large compressors and chillers |
| 2-1/8" | 53.98 mm | Commercial and industrial HVAC systems |

FAQs of ACR Copper Tubing
1. What does ACR copper stand for?
ACR stands for Air Conditioning and Refrigeration. ACR copper tubing is specifically manufactured for use in HVAC and refrigeration systems that transport refrigerant gases.
2. What is the difference between ACR copper and regular copper pipe?
ACR copper tubing is factory-cleaned, dehydrated, and sealed to prevent contamination, while regular copper pipe is not sealed and may contain interior oxidation. Also, ACR tubing is measured by outside diameter (OD), whereas plumbing copper uses nominal size (NPS).
3. How is ACR copper tubing stored and shipped?
Each end of ACR tubing is factory sealed with caps or plugs to prevent dirt, dust, and moisture from entering the tubing before installation. Always keep it sealed until use.
4. Can ACR tubing be bent?
Yes. Soft ACR copper tubing can be bent manually or with a tube bender for tight radius installations. Hard-drawn tubing should not be bent and requires elbow fittings.
