What Is ACR Type L Copper Tube?
ACR copper tube is prepared for air-conditioning and refrigeration service where internal cleanliness is especially important. This product combines rigid Type L copper construction with a cleaned, dehydrated interior and protective factory caps to help preserve the tubing until installation.
Type L provides a heavier wall than Type M copper tube while remaining widely used in plumbing, mechanical, HVAC, and refrigeration-related applications where its wall thickness and service rating are appropriate.
Why Cleaned, Dehydrated & Capped Matters
Moisture, dirt, oil, metal particles, and other contaminants can negatively affect refrigeration and air-conditioning systems. Maintaining a clean internal tube surface helps protect sensitive system components and supports proper installation practices.
The tube is cleaned and dehydrated before the ends are capped. Keep both protective caps in place until immediately before cutting, fitting, brazing, or connecting the tubing.
ACR Tube vs. Standard Plumbing Copper
ACR Cleaned & Capped Tube
- Prepared for air-conditioning and refrigeration service
- Internally cleaned and dehydrated
- Factory capped for protected handling
- Cleanliness is maintained until installation
- Commonly selected for refrigerant piping systems
Standard Plumbing Copper Tube
- Primarily intended for water and plumbing applications
- May not be supplied with protected internal cleanliness
- Typically selected by Type K, L, or M classification
- Commonly used for potable water and building-service piping
- Application requirements differ from ACR service
Why Choose Type L Wall Construction?
Added Wall Thickness
- Heavier wall than Type M copper tube
- Provides added mechanical durability
- Suitable for demanding mechanical applications when approved
- Widely used across commercial piping systems
Rigid 20-Foot Lengths
- Useful for long straight refrigeration runs
- Reduces the number of intermediate joints
- Well suited for commercial and industrial installations
- Provides clean, aligned mechanical-room piping
Common Applications
Air Conditioning & Refrigeration
- Commercial air-conditioning systems
- Refrigeration equipment
- Condensing-unit piping
- Evaporator connections
- Heat-pump systems
- Refrigerant distribution piping
Mechanical & Specialty Systems
- Mechanical-room piping
- Commercial HVAC installations
- Equipment replacement projects
- Industrial cooling systems
- Institutional mechanical systems
- Other approved clean copper piping applications
Joining ACR Copper Tube
ACR copper tube should be joined using procedures approved for the refrigerant, operating pressure, tube size, fitting system, equipment manufacturer, and applicable mechanical codes.
- Brazed joints: commonly used for air-conditioning and refrigeration copper piping.
- Press connections: may be used with compatible refrigeration-rated press fittings when approved.
- Flared joints: may be used where compatible with the equipment and application.
- Mechanical fittings: may be used when specifically approved for the tubing, refrigerant, pressure, and system.
- Nitrogen purge: commonly used during brazing to help reduce internal oxidation and scale formation.
Installation Guidance
- Confirm the required nominal tube size before ordering.
- Verify that the selected tubing is appropriate for the refrigerant and operating conditions.
- Keep factory caps installed until immediately before installation.
- Inspect tubing and end caps for shipping or handling damage.
- Do not use tubing if the internal surface appears contaminated.
- Cut tubing square using an approved copper tubing cutter.
- Remove burrs without allowing debris to enter the tube.
- Maintain internal cleanliness throughout installation.
- Use approved fittings, brazing alloys, purge procedures, press tools, and joining methods.
- Protect open tube ends whenever installation is interrupted.
- Support tubing according to applicable code and engineering requirements.
- Pressure-test, evacuate, and commission the completed system according to project and equipment requirements.
- Installation should be completed by qualified HVAC or refrigeration personnel.

Frequently Asked Questions
What does ACR copper tube mean?
ACR refers to copper tubing prepared for air-conditioning and refrigeration applications where internal cleanliness and moisture control are important.
What does cleaned and capped mean?
The tubing is internally cleaned and dehydrated, then the ends are capped to help prevent dirt, moisture, oil, and other contaminants from entering before installation.
Why should the caps stay installed?
The protective caps help maintain the internal condition of the tubing during shipping, storage, and jobsite handling. Remove them only when the tube is ready to be installed.
What is Type L copper tube?
Type L is a medium-wall copper tube classification with a heavier wall than Type M and a lighter wall than Type K of the same nominal size.
How long is each piece?
Each piece in this product family is supplied as one 20-foot straight length.
Is this product sold by the foot?
No. This product is sold as a complete 20-foot stick. The displayed product price applies to the selected 20-foot length.
Can this tubing be used for air conditioning?
Yes. This product is intended for approved air-conditioning and refrigeration piping applications when properly selected for the refrigerant, pressure, temperature, and equipment.
Can this tubing be used with modern refrigerants?
Use depends on the tube size, wall thickness, design pressure, refrigerant, equipment, joining method, and applicable system requirements. Confirm compatibility before installation.
Can ACR copper tube be brazed?
Yes. Brazing is commonly used for refrigeration and air-conditioning copper piping when completed using approved fittings, alloys, purge procedures, and installation practices.
Should nitrogen be used during brazing?
A low-flow nitrogen purge is commonly used during brazing to help reduce internal oxidation and scale formation. Follow equipment-manufacturer and project requirements.
Can press fittings be used?
Compatible refrigeration-rated press fittings may be used when the fitting manufacturer approves the tubing, refrigerant, pressure, temperature, and application.
Can this tubing be flared?
Flared connections may be used when the tube size, fitting, equipment, refrigerant, and application are specifically approved for that joining method.
What is the advantage of a 20-foot straight length?
A 20-foot straight length allows longer continuous piping runs with fewer intermediate joints, which can be useful in commercial HVAC, refrigeration, and mechanical installations.
Is this the same as standard Type L plumbing copper?
Both may use Type L wall construction, but ACR tubing is prepared and protected for refrigeration and air-conditioning service with additional attention to internal cleanliness and moisture control.
Why is internal cleanliness important?
Moisture, scale, dirt, oil, and other contaminants can interfere with refrigeration-system performance and may damage sensitive system components. Clean handling helps protect the completed system.
