Seamless copper coil for air-conditioning and refrigeration, 50 ft length with 7/8 in outside diameter and .045 in wall thickness

  • Product typeDrain Components
  • Seamless copper coil resists leaks in ACR systems
  • 50 ft continuous length reduces joints on long runs
  • Soft temper allows hand bending without kinking
  • 700 psi rating at 200 °F handles high-pressure refrigerant
  • ASTM B280 C12200 grade ensures purity for cooling circuits

Copper Coil for ACR Systems

This 50 ft seamless copper coil is built for air-conditioning and refrigeration piping. It suits installers who need a continuous run without joints for new installations or service replacements.

ASTM B280 Grade C12200

The tubing meets ASTM B280 with UNS C12200 copper in soft temper. That standard and alloy combination is the single spec that confirms the coil is approved for refrigerant service.

Fits 7/8 in Fittings at 700 psi

The 7/8 in outside diameter and .75 in inside diameter match standard ACR fittings, while the .045 in wall supports 700 psi at 200 °F. The soft temper allows hand bending, freeing the installer from pre-formed elbows.

Questions about this item

How much tubing do I get from the 50 ft coil once it is installed in a system?

The coil provides exactly 50 ft of seamless copper tubing, so the installed length matches the coil length with no hidden waste.

What does the ASTM B280 standard mean for the 700 psi rating in daily use?

ASTM B280 certifies the C12200 copper meets composition and mechanical requirements, so the 700 psi rating at 200 °F is a verified design limit for air-conditioning and refrigeration service.

What minimum bend radius or clearance does the 7/8 in OD coil need to fit without kinking?

The soft-temper tubing with 0.045 in wall thickness can be bent by hand to tight radii, but allow at least a few inches of straight run at each end for flare or braze connections.
