Choose ACR instead of plumbing tube
ASTM B280 and EN 12735-1 identify refrigeration service, actual-OD sizing and the required internal condition.

Specify clean, dry and sealed refrigeration copper tubing for split AC, VRF/VRV, chillers, cold rooms and engineered HVACR systems.

Refrigeration-grade copper tubing
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
ASTM B280 and EN 12735-1 identify refrigeration service, actual-OD sizing and the required internal condition.
Choose O60 soft pancake coil, level-wound coil for OEM processing or H58 hard-drawn straight tube.
Specify clean, dry, oil-free interiors and capped or sealed ends before quotation and dispatch.
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
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.
Other referenced standards include JIS H3300 C1220T, AS 1571 and BS 2871 C106. Confirm the required edition and all project-specific cleanliness criteria.
Material and service identity
Chemistry identifies the copper grade; ASTM B280 or EN 12735-1 defines the finished refrigeration tube requirements.
| Element or property | Published reference | Purchasing significance |
|---|---|---|
| Copper plus silver | 99.9% minimum | Base purity for C12200 DHP copper |
| Phosphorus | 0.015–0.040% | Deoxidised copper chemistry suited to brazed tube applications |
| Oxygen | 0.001% maximum | Controlled oxygen content for DHP grade |
| Interior | Clean, dry and oil-free | Helps control contamination inside a sealed refrigerant circuit |
| Ends | Capped or sealed | Maintains internal condition during handling and transport |
Configure before enquiring
Open the interactive builder with ACR Copper Tubes preselected. Use it to visualise the product and organise the grade, dimensions, temper, form, length, quantity and destination required for technical review.
Choose soft pancake coil, level-wound coil or hard-drawn straight tube.
State standard, grade, actual OD, wall, temper, length and refrigerant.
Add quantity, testing, MTC, TPI, packing and delivery destination.
Frequently ordered dimensions
These published combinations are purchasing references. The system designer must confirm the wall and pressure rating for the refrigerant, temperatures, joining method and design code.
HVACR system applications
Suction and liquid refrigerant lines sized by the system designer and equipment requirements.
Branch and distribution piping where cleanliness, tube sizing and approved brazing practice are critical.
Refrigeration copper pipe for cold rooms, display equipment and packaged refrigeration systems.
Interconnecting ACR tubing selected for refrigerant, pressure, temperature and project code.
HVACR copper tube for engineered cooling circuits and temperature-control equipment.
Level-wound coils for controlled feeding, cutting and forming on manufacturing lines.
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
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.
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.
H58 straight copper tube supports plant-room, riser and fabricated assemblies where alignment and dimensional control matter.
Chiller, cold-room and refrigeration copper tube enquiries should identify the applicable standard, cleanliness, joining process, operating conditions and inspection scope.
Use ASTM B280 Copper Tubes for exact-standard procurement and Level Wound Copper Coils for OEM processing coils.
Cleanliness, traceability and inspection
Ask for the applicable MTC, cleanliness condition, end sealing, inspection scope, marking and export documents in the original enquiry.

Before requesting a quotation
ACR means air conditioning and refrigeration. It identifies copper tube prepared for sealed refrigerant service rather than ordinary water plumbing.
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.
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.
The published range includes O60 soft pancake coils, level-wound coils for OEM use and H58 hard-drawn straight tubes.
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.
Yes. Open the 3D product builder with ACR Copper Tubes selected, prepare the requirement and send it for technical review.
