GOORY 3/8″ OD x 0.328″ ID, 50 Ft Coil


GOORY Copper Tubing 3/8 inch coil

Check Price on Amazon

Specification: Annealed UNS C12200 seamless copper, 3/8″ OD × 0.328″ ID, wall 0.024″, 50 ft. This tube adheres to ASTM B280, offering good flexibility for easy installation, strong thermal conductivity, and durable corrosion resistance. Nitrogen-filled during production reduces impurities and oxidation, extending service life in air conditioners, coolers, and refrigerators.

Best for: Mid-size refrigeration lines and DIY HVAC projects where a longer 50 ft coil is convenient. Choose this if you need a balance of flexibility and diameter for mid-range systems. Caution: ensure the wall thickness and diameter align with your system’s connectors and fittings.

Specification: UNS C12200 seamless copper, 1/4″ OD × 0.195″ ID, wall 0.028″, length 10 ft. Meets ASTM-B280 with nitrogen-filled tubes for reduced impurities and improved oxidation resistance. It offers good bending and installation ease, suitable for compact circuits and small appliances.

Best for: Small, tight installations like compact refrigeration lines or DIY repairs. Better for shorter runs than longer coiled sections. Caution: short length may require more joints and fittings in complex systems.

GOORY 3/4″ OD x 0.687″ ID, 50 Ft Coil


GOORY 3/4 inch copper tubing

Check Price on Amazon

Specification: UNS C12200 seamless copper, 3/4″ OD × 0.687″ ID, wall 0.031″, 50 ft. ASTM B280 compliant, with nitrogen charging to reduce impurities and resist oxidation. Notable for high flow capability and durability in larger refrigerant circuits.

Best for: Large-scale HVAC systems or long condenser runs where higher diameter is needed. Choose this if your project demands greater internal volume. Caution: the larger diameter requires appropriate fittings and space for bending.

GOORY 1/4″ OD x 0.187″ ID, 50 Ft Coil


GOORY 1/4 inch copper tubing 50 ft

Check Price on Amazon

Specification: UNS C12200 seamless copper, 1/4″ OD × 0.187″ ID, wall 0.031″, 50 ft. Follows ASTM B280, nitrogen-filled to minimize impurities and oxidation. This tube offers a balance of manageable diameter and adequate length for practical DIY and service work.

Best for: General purpose refrigeration projects and repairs where a standard 1/4″ line is common. Caution: ID is small; ensure fittings match your connector sizes and refrigerant pressures.

BELLA BAYS 7/8″ OD x 0.796″ ID, 50 ft


BELLA BAYS copper tubing 7/8 inch

Check Price on Amazon

Specification: UNS C12200 copper, 7/8″ OD × 0.796″ ID, wall 0.039″, seamless coil, 50 ft. Meets ASTM-B280, with nitrogen charging to deter oxidation and condensation. It provides strong thermal performance and durability in large-chassis systems.

Buying Guide

What should I consider before buying ASTM B280 copper tube?

  • Diameter needs: Choose OD and ID that match your system fittings and refrigerant flow requirements.
  • Length: Select coil length to minimize joints but fit your installation space and routing challenges.
  • Wall thickness: Thicker walls offer higher resistance to pressure and corrosion, but require larger fittings and more bending space.
  • Alloy and standards: Look for UNS C12200 copper and ASTM B280 compliance for reliable thermal performance and durability.
  • Manufacturing quality: Nitrogen charging and pressure testing are signs of impurity control and strength.
  • Installation handling: Flexible coils are easier to route; consider your ability to make clean bends without kinking.

How to choose by application

  • Small DIY projects: 1/4″ OD tubes are common for compact appliances and repairs.
  • Medium HVAC runs: 3/8″ OD offers a balance of flow and flexibility.
  • Large systems: 3/4″ OD and larger provide higher flow for condensers and long runs.

Installation tips

  • Use compatible fittings and proper tubing cutters to avoid deformation.
  • Ensure proper nitrogen test or pressure test procedures as specified for your tubing.
  • Protect exposed ends from oxidation during storage and assembly.
