Refrigeration-grade copper tubing
Protect the refrigerant circuit with the correct tube specification.
ACR means air conditioning and refrigeration. ACR copper tube is ordered by actual outside diameter and supplied for sealed refrigerant systems. The published group range covers C12200 DHP and C10200 oxygen-free copper in soft coils, level-wound coils and hard-drawn straight lengths.
The internal condition matters as much as the dimensions. Refrigeration copper tubing should be clean, dry and sealed to control moisture and contamination before installation. State the standard, alloy, OD, wall, temper, supply form, length, refrigerant, quantity and required documents in the RFQ.
A more reliable HVACR purchase
Reduce specification gaps before material reaches the site.
Select the correct supply form
Choose O60 soft pancake coil, level-wound coil for OEM processing or H58 hard-drawn straight tube.
Confirm cleanliness and sealing
Specify clean, dry, oil-free interiors and capped or sealed ends before quotation and dispatch.
Configure the product visually
Use the 3D product builder to organise the tube form and purchasing information before technical review.
Final refrigerant suitability and working conditions remain the responsibility of the system designer and governing project specification.
Technical specification
Published ACR copper tube supply range
Values are based on the group’s published ACR range. Final tolerances, wall selection, pressure suitability and availability are confirmed against the governing standard and RFQ.
¼–4⅛ inch

HVACR system applications
Refrigeration copper tubing selected around the system design
Split and ducted AC
Suction and liquid refrigerant lines sized by the system designer and equipment requirements.
VRF and VRV systems
Branch and distribution piping where cleanliness, tube sizing and approved brazing practice are critical.
Commercial refrigeration
Refrigeration copper pipe for cold rooms, display equipment and packaged refrigeration systems.
Chiller installations
Interconnecting ACR tubing selected for refrigerant, pressure, temperature and project code.
Industrial process cooling
HVACR copper tube for engineered cooling circuits and temperature-control equipment.
OEM production
Level-wound coils for controlled feeding, cutting and forming on manufacturing lines.
Selection note
Do not select ACR wall thickness from equipment tonnage alone. Confirm refrigerant, design pressure, operating temperatures, OD, joint type and applicable code.

ACR tube forms and system language
Match the copper tube form to the HVACR purchasing requirement.
Pancake and soft copper coils
Bright-annealed pancake copper coil and flexible copper tube coil are intended for routed refrigerant lines. State actual OD, wall thickness, coil length, O60 temper and sealed-end requirements.
VRF and VRV copper tubing
For VRF or VRV piping, provide the equipment schedule, refrigerant, line duty and design pressure so the specified tube size and wall can be reviewed.
Hard-drawn straight tube
H58 straight copper tube supports plant-room, riser and fabricated assemblies where alignment and dimensional control matter.
Chiller and refrigeration systems
Chiller, cold-room and refrigeration copper tube enquiries should identify the applicable standard, cleanliness, joining process, operating conditions and inspection scope.
Choose the correct page
Use ASTM B280 Copper Tubes for exact-standard procurement and Level Wound Copper Coils for OEM processing coils.
Cleanliness, traceability and inspection
Define the refrigerant-service requirements before dispatch.
Ask for the applicable MTC, cleanliness condition, end sealing, inspection scope, marking and export documents in the original enquiry.

Frequently asked questions about ACR copper tubes
What does ACR mean in copper tubing?+
ACR means air conditioning and refrigeration. It identifies copper tube prepared for sealed refrigerant service rather than ordinary water plumbing.
Is ACR tube measured by ID or OD?+
ACR copper tubing is ordered by actual outside diameter. The internal diameter changes with wall thickness and should not be used as the primary size description.
What is the difference between ACR tube and Type L plumbing tube?+
ASTM B280 ACR tube is actual-OD sized, internally clean and sealed for refrigerant service. Type L under ASTM B88 is nominally sized water tube. Use the product required by the system specification.
Which supply forms are available?+
The published range includes O60 soft pancake coils, level-wound coils for OEM use and H58 hard-drawn straight tubes.
Can ACR tubing be used with R410A or R32?+
The published range identifies these refrigerants among common applications. The engineer must confirm OD, wall thickness, working pressure, temperatures, joints and design code for the specific system.
Can I configure ACR Copper Tubes in the 3D builder?+
Yes. Open the 3D product builder with ACR Copper Tubes selected, prepare the requirement and send it for technical review.
