BELLA BAYS Copper Tubing 1/4″ Coil

Specification highlights a 1/4″ (6.35 mm) OD and 0.195″ (4.95 mm) ID with a wall thickness of 0.028″ (0.7 mm). The tubing length is 25 ft, seamless and annealed for flexible handling. It conforms to ASTM-B280 and uses UNS C12200 copper, which is known for its thermal conductivity and corrosion resistance. This makes it suitable for HVAC systems, refrigerators, and DIY projects where easy bending and reliable performance are essential.
Best for: Small to mid-range DIY projects and compact HVAC repairs where a precise 25 ft run is needed. Better for users who want a predictable, manageable coil that’s easy to work with in tight spaces.
Caution: The 25 ft length may require spooling or cutting in multiple runs for larger installations.
GOORY Copper Tubing 3/8″ Coil 50 ft

Specification shows 3/8″ (9.53 mm) OD, 0.328″ (8.33 mm) ID, wall thickness 0.024″ (0.6 mm), length 50 ft. This UNS C12200 seamless copper tubing is nitrogen-filled during production to reduce impurities and resist oxidation and condensation. It adheres to ASTM-B280 and is designed for easy installation with excellent thermal conductivity and corrosion resistance. The longer 50 ft length is ideal for longer runs in larger cooling systems.
Best for: Mid-size HVAC installations and longer tubing runs where flexibility and durability matter. Better for projects requiring fewer joints and fewer connections over a longer distance.
Caution: While length is practical, heavier 3/8″ tubing can be harder to maneuver in tight spaces without proper supports.
GOORY Copper Tubing 1/2″ Coil 50 ft

Specification: 1/2″ (12.7 mm) OD, 0.445″ (11.3 mm) ID, wall thickness 0.028″ (0.7 mm), 50 ft length. UNS C12200 copper and ASTM-B280 compliance ensure robust performance with strong thermal conductivity and corrosion resistance. Nitrogen-filled production helps maintain purity and resistance to condensation, contributing to a longer service life in refrigeration and HVAC applications.
Best for: Systems needing higher flow and larger refrigerant passages, such as mid-to-large scale cooling setups. Better for installations where fewer but larger tubes are beneficial.
Caution: The larger diameter requires more space for routing and may increase weight during handling and installation.
GOORY Copper Tubing 1/4″ Coil 50 ft

Specification includes 1/4″ (6.35 mm) OD x 0.187″ (4.75 mm) ID, wall thickness 0.031″ (0.8 mm), length 50 ft. This ends-to-end seamless tubing is nitrogen-filled to minimize oxidation and impurities, with strict pressure testing for reliability. It complies with ASTM-B280 and is designed for easy bending and installation in tight spaces.
Best for: DIY projects and compact installations where a 1/4″ line is the preferred size due to space constraints. Choose this if you need a balance between bendability and refrigerant flow in narrow routes.
Caution: Slightly thicker wall than some 1/4″ options may impact flexible bending tolerance in extremely tight corners.
BELLA BAYS Copper Tubing 1/4″ 10 ft Coil

Specification: 1/4″ OD x 0.195″ ID, 0.028″ wall, 10 ft length. Seamless coil, annealed UNS C12200 copper that meets ASTM-B280. The shorter coil is ideal for precise, small-scale tasks and quick field repairs, while maintaining good thermal performance and corrosion resistance over time.
Best for: Short runs and field repairs where a compact coil is easier to manage. Better for stocking in service trucks for quick fixes.
Caution: Short length means more joints if your project requires longer runs, which can introduce more potential leak points if not sealed well.
TAUROX 50 Ft Copper Tubing 1/4″ OD

Crafted from premium C12200 copper with 99.9% purity and ASTM B280 compliance, this seamless tube features an impressively smooth surface for superior sealing and leak resistance. The uniform wall thickness supports reliable refrigerant flow and straightforward bending. It’s designed to be easy to cut and shape, making it suitable for professionals and DIY enthusiasts alike.
Best for: Projects requiring robust, leak-resistant tubing with smooth seals and straightforward customization. Better for both contractors and ambitious DIYers handling multiple connections.
Caution: The 50 ft length may require careful storage and handling to prevent kinking during traversal through tight conduits.
Buying Guide: Copper Tubing For Refrigeration And HVAC
- Size matters: Decide between 1/4″, 3/8″, and 1/2″ OD based on refrigerant flow needs and compatibility with your system’s fittings.
- Wall thickness and durability: Thicker walls (0.028″ or more) offer better leak resistance and higher pressure tolerance but are less flexible than thinner options.
- Material quality: Look for UNS C12200 copper and ASTM-B280 compliance for reliable thermal performance and corrosion resistance.
- Length considerations: Longer coils reduce joints but require more space and careful routing; shorter coils are easier to handle in tight areas.
- Manufacturing aids: Nitrogen-filled production helps minimize oxidation and impurities, contributing to longer service life.
- Installation context: For DIY projects, choose coils with easy bendability and predictable performance. For professional jobs, ensure the tubing matches your system’s exact specifications and fitting styles.
Frequently Asked Questions
