1 3/8 in Copper Coil for ACR Systems

This 50 ft coil of seamless copper tubing is built for air conditioning and refrigeration installations. The soft temper allows easy bending around obstacles without kinking. Material grade C12200 meets ASTM B280 for reliable service in refrigerant circuits.

Upgrade from smaller or rigid line sets

Switching to 1 3/8 in outside diameter tubing increases flow capacity for larger tonnage equipment or longer runs. The 625 psi rating at 200 Degrees F supports high-pressure refrigerant cycles. The jump is worth it when existing lines restrict flow or cannot handle system operating pressures.

Verify fitting compatibility and local codes

Confirm that 1.265 in inside diameter matches your flare or braze fittings before ordering. The .055 in wall thickness determines brazing technique and support spacing requirements. Check that 400 Degrees F maximum temperature exceeds your design conditions and that ASTM B280 is accepted by the authority having jurisdiction.

Questions about this item

What is the outside diameter of the Mueller D 22050P coil tubing?

The outside diameter is 1 3/8 in, which matches the copper tube size listed for this product.

How do you make a leak-free joint with this soft-temper copper coil?

Use a tubing cutter for a square cut, deburr the ends, then braze with a phosphorus-copper alloy; the soft temper makes it easy to bend but requires proper support during brazing.

When should this C12200 copper coil be replaced in an ACR system?

Replace it if you find wall thinning below the 0.055 in spec, green corrosion deposits, kinks that restrict flow, or after any system burnout that contaminates the interior.
