Copper refrigeration tube is soft annealed copper tubing manufactured for air-conditioning, refrigeration, and related mechanical systems. Unlike rigid hard-drawn copper tube supplied in straight lengths, refrigeration tubing is supplied in coils so it can be routed through walls, ceilings, equipment areas, and other spaces with fewer fittings and directional changes.

The tubing is dehydrated and sealed after manufacturing to help keep the interior dry and protected from dirt, moisture, and other contaminants prior to installation. This internal cleanliness is particularly important in refrigeration and air-conditioning systems.

Refrigeration and air-conditioning systems require tubing with a clean, dry internal surface. Moisture, dirt, oil, metal particles, and other contaminants can negatively affect system performance and refrigeration components.

Dehydrating and sealing the tube helps preserve the condition of the interior from the time it leaves the manufacturer until it is opened for installation. Keep the ends sealed until immediately before cutting, fitting, or connecting the tubing.

Copper refrigeration tubing must be joined using methods approved for the refrigerant, operating pressure, tube size, equipment manufacturer, project specification, and applicable mechanical codes.

• Brazed joints: commonly used for refrigeration and air-conditioning piping.
• Flared joints: may be used with compatible equipment and fittings when specified.
• Mechanical refrigeration fittings: may be used when specifically approved for the tubing, refrigerant, pressure, and application.
• Nitrogen purge: commonly used during brazing to help reduce internal oxidation and scale formation.

• Confirm the required outside diameter and coil length before ordering.
• Verify that ASTM B280 refrigeration tube is appropriate for the intended system.
• Keep tube ends sealed until immediately before installation.
• Inspect the coil for shipping or handling damage before use.
• Uncoil tubing carefully to prevent flattening, kinking, or twisting.
• Use an approved tubing cutter to produce a clean, square cut.
• Remove burrs without allowing debris to enter the tube.
• Maintain internal cleanliness throughout installation.
• Use approved bending tools when tighter bends are required.
• Do not exceed the minimum bend radius recommended for the tubing size.
• Use approved brazing alloys, purge procedures, fittings, and joining methods.
• Pressure-test, evacuate, and commission the completed refrigeration system according to applicable requirements.
• Installation should be completed by qualified HVAC or refrigeration personnel.
