GOORY Copper Tubing 3/4 in OD x 25 ft - Seamless Refrigeration Coil

In this review the GOORY Copper Tubing 3/4 in OD x 25 ft is assessed for HVAC, refrigeration and DIY use; it is best for installers and makers who need a long, flexible, seamless copper coil that meets refrigeration standards. The single biggest reason to buy is its construction from annealed UNS C12200 copper with ASTM-B280 conformity and nitrogen charged treatment, which together deliver reliable thermal conductivity and extended resistance to oxidation and corrosion.

Key Features

• Dimension and fit: The 3/4 in OD with a 0.687 in ID and 0.031 in wall thickness provides consistent sizing for common refrigeration and HVAC flare or sweat fittings.
• Length and handling: A 25 ft coil gives installers room to route lines without multiple joints, reducing leak points and simplifying installations.
• Material quality: Made from Annealed UNS C12200 copper, it offers excellent thermal conductivity for efficient heat transfer in refrigeration circuits.
• Protective treatment: The nitrogen charged process reduces oxidation and impurities, helping the tube resist corrosion and condensation over time.
• Workability: Being seamless and soft, the tubing bends smoothly and can be cut and shaped for custom HVAC, ACR or DIY projects without excessive kinking when handled properly.

Who It's For

The tubing is aimed at HVAC technicians, refrigeration installers and hobbyists who need a reliable ACR tube for refrigerators, freezers, air conditioners or bespoke projects. Its compliance with ASTM-B280 and the UNS C12200 copper grade make it a practical choice for professional service work as well as demanding DIY builds.

People who should look elsewhere are those requiring rigid hard temper lines for structural runs, or projects needing pre-formed assemblies; if your work demands pre-bent, flared assemblies or extremely high corrosion resistance coatings beyond nitrogen treatment, consider specialized alternatives.

Pros & Cons

Pros

• Seamless annealed copper gives consistent thermal performance and straightforward bending for custom runs.
• Nitrogen charged treatment improves resistance to oxidation and helps extend system life.
• The 25 ft coil reduces the need for multiple joints, saving time on installations.
• Versatile use across refrigeration, HVAC, electrical conductivity projects and craft work.

Cons

• Some users report mixed results on surface flatness and reaming ability, so tight-tolerance fittings may require extra prep.
• Soft coil can kink if bent sharply without proper tooling, so careful handling is required.

Specifications

Our Verdict

The GOORY 3/4 in copper tube is a solid choice for technicians and DIYers who need a long, flexible refrigeration tube that balances thermal performance and corrosion resistance. It represents good value when installers want a seamless, workable coil that meets industry standard ASTM-B280 and benefits from nitrogen treatment, though careful handling is advised to avoid kinks and some prep may be needed for precision fittings.

Frequently Asked Questions

Is this tubing ready for refrigeration use?
Yes, it is made from UNS C12200 copper and conforms to ASTM-B280, which makes it suitable for refrigeration and ACR applications.

Can the coil be bent and flared on site?
Yes, the tubing is annealed and soft for bending and can be used with sweating or flare fittings, though sharp bends require proper tooling to avoid kinks.

Does the nitrogen charged treatment prevent corrosion?
The nitrogen charge reduces oxidation and impurities to improve corrosion resistance and lifespan, but environmental exposure and installation practice still affect longevity.
