BELLA BAYS Copper Tubing 50 ft
Best for: HVAC contractors and serious DIYers who need long runs without joints. This 50 ft coil uses 7/8″ OD x 0.796″ ID with a 0.039″ wall, offering high flexibility and robust thermal performance. The seamless coil design reduces leak points and simplifies bending work in tight spaces.
Why chosen: It adheres to ASTM-B280 for refrigeration copper and uses UNS C12200 copper, ensuring good conductivity and corrosion resistance. Nitrogen charged treatment helps resist oxidation, extending equipment lifespan.
Limitation: Long coils can be harder to store in compact spaces; ensure your workspace has enough room to uncoil safely.
BELLA BAYS Copper Tubing 25 ft
Best for: Mid-sized refrigeration or AC installations where moderate length minimizes waste. The 25 ft coil maintains the same OD/ID as the longer version, offering consistent performance in smaller runs.
Why chosen: Same UNS C12200 and ASTM-B280 specifications provide dependable conductivity and corrosion resistance. Nitrogen treatment supports longer lifespan in condenser lines.
Limitation: May require spooling or clamps to manage a mid-length coil during installation.
BELLA BAYS Copper Tubing 10 ft
Best for: Quick-field repairs or small system tweaks where a short, easy-to-handle length is ideal. The 10 ft coil reduces waste on minor projects.
Why chosen: The same high-grade copper and ASTM-B280 compliance ensure reliable performance in compact installations. Nitrogen charging supports oxidation resistance.
Limitation: Short length may necessitate additional connections or couplings for longer runs.
ELECTRAPICK Copper Tubing 50 ft
Best for: Professional installers needing robust, corrosion-resistant tubing with excellent heat transfer. Suitable for both HVAC and refrigeration lines that demand higher durability.
Why chosen: Made from premium C12200 copper and nitrogen-filled to reduce impurities and oxidation, improving longevity. Seamless design supports better pressure handling.
Limitation: Looks for a careful bend radius; improper bending can cause kinks in a long coil.
GOORY Copper Tubing 50 ft
Best for: Installing longer runs in new or upgraded HVAC/refrigeration setups where reliable conductivity matters. The 50 ft coil format supports fewer joints on large projects.
Why chosen: UNS C12200 copper with ASTM-B280 compliance and nitrogen treatment offers good corrosion resistance and long service life. Flexible enough for routing in tight spaces.
Limitation: Ensure you have a way to store and manage a 50 ft coil during transport and on-site setup.
Buying Guide: How To Choose The Right 7/8″ Copper Tube
What to consider when selecting copper tubing for HVAC, refrigeration, or DIY use:
- Length needs: Choose a coil length that minimizes waste and joints for your project size. Longer coils reduce joints but require more storage.
- Wall thickness: Typical thickness is 0.039″ (1.0 mm). Thicker walls offer extra durability but are less flexible; match to system pressure requirements.
- Material standard: Look for UNS C12200 copper and ASTM-B280 compliance for refrigeration-grade tubing and consistent thermal properties.
- Seamless vs coil: Seamless coils reduce leakage points and are easier to form; ensure coil packaging supports your installation style.
- Oxidation resistance: Nitrogen-charged treatments help prevent oxidation and condensation, extending tube life in condenser lines.
- Compatibility: Confirm compatibility with standard copper fittings and soldering or crimping methods used in your project.
- Handling and storage: Consider uncoiling requirements, clamps, and space to avoid kinking or crushing the tubing during work.
Practical Tips for Installation
- Plan bends with generous radii to avoid kinks, especially on long coils.
- Clean and deburr tubing ends before joining to fittings.
- Use appropriate flux and curing methods for wetted joints to ensure leak-free connections.
- Inspect coils for any signs of damage or oxidation prior to use.
FAQ
- What does 7/8″ OD mean for copper tubing?
It refers to the outside diameter of the tube, which determines fitting size and bend radii. - Is nitrogen-filled copper tubing more durable?
Yes, nitrogen treatment helps reduce impurities and oxidation, potentially extending service life. - Can I use standard solder fittings with 7/8″ copper tubing?
Yes, but ensure the fittings are compatible with the tube ID and your chosen joining method. - Which length is best for a small repair job?
A shorter coil (like 10 ft or 25 ft) minimizes waste and storage needs for quick fixes. - Are these tubes suitable for both HVAC and refrigeration?
Yes, these coils are designed to meet refrigeration-grade specifications and are commonly used in HVAC systems. - What safety considerations apply to large coils?
Uncoil and handle with care to prevent kinks, injuries, or damage to the tubing and surrounding components.
