5/16 in copper coil for ACR systems

This 50 ft coil of Type ACR copper tubing is made for air-conditioning and refrigeration installations. The soft temper allows tight bends without fittings, reducing joint count and leak paths. It meets ASTM B280 and is rated to 1197 psi. Operating range covers 100 to 400 degrees F.

Suits installers needing long, continuous runs

The 5/16 in outside diameter fits many mini-split and light-commercial refrigerant circuits. Builders who require larger diameters such as 3/8 in or 1/2 in should select a different size. Projects that demand hard-drawn straight lengths or pre-insulated tubing will not be served by this soft coil.

0.032 in wall thickness sets pressure rating

With a 0.032 in wall and 0.249 in inside diameter, the tube handles 1197 psi maximum working pressure per ASTM B280. Thinner walls would lower the rating; thicker walls would reduce flow area and increase cost. Verify your system design pressure against this figure before purchase.

Questions about this item

Will the 0.032 in wall thickness on this 5/16 in OD copper coil need replacement from corrosion or vibration fatigue?

The soft Type ACR copper meets ASTM B280 and resists typical refrigerant corrosion; vibration fatigue depends on support spacing, not the tubing itself.

What pressure or temperature limit will this 1197 psi max-pressure coil reach first during continuous HVAC operation?

The 400 °F temperature ceiling is reached well before the 1197 psi burst rating under normal air-conditioning and refrigeration loads.

Does the bare copper surface radiate noticeable heat or require insulation when running at 400 °F all day?

Uncoated copper conducts heat rapidly; at sustained high temperature the coil will feel very hot and should be insulated for safety and efficiency.
