GOORY Copper Tubing 50 Ft – 1/2″ OD x 0.445″ ID
Best for: professional installers needing a longer run with reliable performance. This 50-foot coil uses annealed UNS C12200 copper and complies with ASTM B280, delivering excellent flexibility for easy routing in HVAC and refrigeration systems. It offers strong thermal conductivity and corrosion resistance for long service life in demanding environments.
Why selected: The 50-foot length reduces joints in longer installations, and nitrogen-filled production minimizes impurities and oxidation. Suitable for DIY projects that require a sturdy, durable coil with proven workmanship.
Caution: Long coils can be harder to maneuver in tight spaces; plan routing to minimize bends and ensure smooth acceptance at connections.
GOORY Copper Tubing 100 Ft – 1/2″ OD x 0.445″ ID
Best for: large-scale HVAC or refrigeration installations with fewer splices. The 100-foot coil maintains the same 0.028″ wall thickness and 0.445″ ID, delivering the same high-quality C12200 copper and ASTM-B280 compliance as shorter versions while reducing joint count.
Why selected: It balances durability and install efficiency, ideal for technicians working on extended runs. Nitrogen treatment minimizes oxidation and condensation, extending component life in cooling systems.
Caution: Transport and storage of long coils require secure handling to prevent kinks or damage during shipping or site work.
GOORY Copper Tubing 10 Ft – 1/2″ OD x 0.445″ ID
Best for: quick repairs or compact installations where a shorter coil is more practical. This 10-foot length matches the same high standards of C12200 copper and ASTM-B280 compliance, offering ready-to-use flexibility for tight layouts.
Why selected: Short runs reduce handling complexity and are ideal for retrofit projects or component replacements within limited spaces. The tubing remains easy to cut and bend by hand, facilitating on-site adjustments.
Caution: For longer runs, multiple pieces may be required, potentially increasing field joints. Ensure quality joints to avoid leaks.
BELLA BAYS Copper Tubing 5 Ft – 1/2″ OD x 0.445″ ID
Best for: small projects, repairs, or tight spaces where a short length is required. The 5-foot coil provides the same UNS C12200 quality and nitrogen-treated protection for oxidation and condensation, ensuring reliability in compact systems.
Why selected: Its short length is ideal for targeted hot- or cold-side runs in compact appliances or minimal installations, reducing waste and handling. Durable, corrosion-resistant copper supports longer lifespans in frequent-use environments.
Caution: Limited length means more joints; ensure high-quality connections to maintain system integrity.
BELLA BAYS Copper Tubing 20 Ft – 1/2″ OD x 0.445″ ID
Best for: general HVAC and refrigeration applications with moderate run lengths. This 20-foot coil maintains the same 0.028″ wall thickness and seamless coil design, offering flexibility and durable performance for typical installations.
Why selected: It provides a balanced option between length and manageability, with nitrogen-treated copper to resist oxidation and condensation. Suitable for projects that require reliable performance without oversized coils.
Caution: As with longer coils, plan routing to minimize unnecessary bends to prevent work-hardening or kinking during installation.
Buying Guide
What should I look for in 1/2″ soft copper tubing?
Key factors are alloy grade (UNS C12200), conformity to ASTM B280, wall thickness, and surface treatment. Nitrogen charging helps prevent oxidation and condensation. Consider coil length, flexibility, and ease of bending for your installation space.
Which length should I choose for my project?
Shorter lengths (5–20 ft) suit tight spaces or repairs, while mid-length coils (10–20 ft) balance handling and fewer joints. Longer coils (50–100 ft) are better for minimal joint counts on larger installations but require careful handling to avoid kinking.
Is 1/2″ tubing suitable for all refrigerants and systems?
1/2″ OD hard coils are commonly used in home HVAC and refrigeration systems. Verify compatibility with your refrigerant type and system design, and ensure connections fit standard fittings for ASTM-B280 copper tubes.
What are the trade-offs between Bella Bays and GOORY products?
Both brands provide UNS C12200 copper that meets ASTM B280. GOORY offers longer coils suitable for extended runs, while Bella Bays provides shorter and mid-length coils for compact or modular layouts. Consider project scope, handling, and the number of joints required when choosing between them.
How does nitrogen charging affect performance?
Nitrogen charging reduces impurities, minimizes oxidation, and helps prevent condensation. This treatment can extend service life by maintaining tube integrity under thermal cycling and varying pressures.
FAQ
- What does 1/2″ OD x 0.445″ ID refer to?
- Is these tubes suitable for DIY projects?
- Why choose a longer coil vs. a shorter coil?
- Do these tubes come with any warranties?
- What maintenance is needed after installation?
The outer diameter is 1/2 inch (12.7 mm) and the inner diameter is 0.445 inch (11.3 mm); wall thickness is about 0.028 inch (0.7 mm).
Yes. They are designed for easy bending, cutting, and forming, making them suitable for DIY HVAC and refrigeration tasks when used with the proper fittings and tools.
Longer coils reduce the number of joints and fittings, improving leak resistance in large installations. Shorter coils are easier to handle in tight spaces and for quick repairs.
Product listings specify material quality and standards compliance; warranties are determined by the seller and retailer and are not specified here.
Routine inspection for leaks, condensation, and corrosion is recommended. Ensure connections remain tight and free of damage; nitrogen-treated copper helps resist long-term corrosion.
