uxcell Refrigeration Tubing 1/8″ OD x 5/64″ ID

Features: 1/8″ OD X 5/64″ ID x 6.5 ft. Outer diameter 3 mm, inner diameter 2 mm. High refrigeration efficiency due to good heat dissipation and strong heat transfer. Copper material offers high temperature resistance and durability. Suitable for refrigerators, freezers, and air conditioners.
Best for: DIY installers and small-service technicians needing a compact, flexible line for short runs or tight bends.
Caution: This tube is a shorter length; plan runs to avoid excessive splicing or too many fittings. Copper tubes are hollow and require careful handling to prevent kinking.
GOORY Copper Tubing 1/4″ OD x 0.195″ ID x 10 ft

Features: Annealed UNS C12200 seamless copper tubing; 1/4″ OD x 0.195″ ID, 0.028″ wall, 10 ft length. Compliant with ASTM-B280, with great flexibility, thermal conductivity, and corrosion resistance. Nitrogen-filled during production for purity, oxidation resistance, and durability.
Best for: Pro installers and hobbyists tackling longer runs and slightly larger connections in HVAC systems and refrigeration projects.
Caution: A longer, thicker-walled tube may require appropriate fittings and tools for secure connections in some setups.
uxcell Refrigeration Tubing, 1/16″ OD x 1/32″ ID

Features: 1/16″ OD x 1/32″ ID x 6.5 ft. High refrigeration efficiency with good heat dissipation. Copper tubing offers heat transfer capability, high temperature resistance, and durability. Suitable for refrigerators and air conditioners.
Best for: Precision work and compact installations where very small tubing is required.
Caution: Very small diameter tubes can be fragile; handle with care to avoid dents or pinching during routing.
BELLA BAYS Copper Tubing 1/4″ OD x 0.195″ ID, 5 ft

Features: UNS C12200 copper, 1/4″ OD x 0.195″ ID, 0.7 mm wall; 5 ft seamless coil. Meets ASTM-B280 with good thermal conductivity and durability. Nitrogen charged treatment helps resist oxidation and condensation, extending component life.
Best for: Short-to-medium length runs in HVAC and refrigeration projects where reliable performance and flexibility are required.
Caution: Shorter coil length may necessitate more connections for longer systems; ensure fittings match tube dimensions precisely.
BELLA BAYS Copper Tubing 1/4″ OD x 0.195″ ID x 25 ft

Features: 1/4″ OD x 0.195″ ID, 0.7 mm wall, 25 ft seamless coil. ASTM-B280 compliant, nitrogen charged to limit oxidation and condensation, supports longer life for air conditioners and refrigerators.
Best for: Medium to long runs in larger HVAC projects and refrigeration systems where a longer flexible coil is advantageous.
Caution: Larger diameter tubing requires compatible fittings and more careful handling to prevent kinking during routing.
BELLA BAYS Copper Tubing 3/8″ OD x 0.320″ ID x 10 ft

Features: UNS C12200 copper, 3/8″ OD x 0.320″ ID, 0.7 mm wall, 10 ft seamless coil. Meets ASTM-B280; flexible, durable, and has high thermal conductivity. Nitrogen charged for oxidation resistance and long life.
Best for: Larger service lines and high-capacity cooling systems where more flow and robust lines are needed.
Caution: Heavier tubing can be harder to maneuver; plan routing and support to prevent sagging or stress at fittings.
Buying Guide: Key Considerations For Soft Drawn Copper Tubing
What size do I need? Determine OD and ID by matching to your compressor connections and fittings. Common options include 1/8″, 1/16″, 1/4″, and 3/8″ diameters.
Should I pick nitrogen-charged tubes? Nitrogen charging reduces oxidation and impurities, helping longevity in condensers and evaporators. It’s especially helpful for longer service life in harsh environments.
Which length is best? Short coils (5–6.5 ft) suit compact or appliance-level work; longer runs (10–25 ft) reduce the number of joints in bigger systems but require careful routing.
Is ASTM-B280 compliance important? Yes, this standard ensures compatibility with typical HVAC and refrigeration fittings and reliability under pressure. Look for tubes labeled as compliant.
How to handle and install? Soft drawn copper tubing is flexible but can kink. Use proper bending tools, avoid sharp bends, and secure tubes to prevent movement and vibration. Confirm fittings match the tube size precisely.
Frequently Asked Questions
- What is soft drawn copper tubing best used for? It is ideal for flexible connections in refrigeration, air conditioning, and HVAC systems, especially where easy bending and compact routing are needed.
- Does nitrogen charging matter for residential work? It can improve longevity by reducing oxidation and impurities, beneficial in longer or more demanding installation conditions.
- How do I choose between 1/4″ and 3/8″ tubes? Choose based on required flow and fitting compatibility. Larger diameters carry more refrigerant but are less flexible.
- Can I reuse old fittings with new copper tubing? Reuse depends on the condition of fittings and seals. Inspect for wear, and replace gaskets and ferrules as needed.
- What safety precautions are needed during installation? Shut off equipment, avoid sharp edges, and wear eye protection. Ensure proper ventilation when soldering or brazing nearby components.
- Are these tubes suitable for DIY projects? Yes, many are designed for DIY enthusiasts, but ensure you follow local codes and use appropriate tools for safe, compliant installations.
