Why selected: Its longer coil length reduces joint points, improving system integrity in longer runs. The nitrogen-treatment through the coil helps minimize oxidation, contributing to longevity in cooling systems.
Caution / Limitation: Longer coils may be less practical for very tight spaces; plan routing to minimize bends and avoid kinking on sharp turns.
GOORY Copper Tubing 10 Ft — 1/4″ OD x 0.195″ ID
Specification: Annealed UNS C12200 Seamless Copper Tubing, 1/4″ OD x 0.195″ ID, 0.7mm wall, 10 ft length. Compliant with ASTM-B280, this coil features high flexibility, strong thermal conductivity, and robust corrosion resistance. Production nitrogen filling reduces impurities and helps resist oxidation and condensation, supporting longer service life for air conditioners, coolers, and refrigerators.
Best for: Small-scale installations, quick field repairs, or projects with limited length requirements where a compact coil is preferable.
Why selected: The compact 10 ft length makes it ideal for tight spaces and quick swaps, while maintaining essential performance characteristics for refrigeration and HVAC tasks.
Caution / Limitation: Shorter length means more splices if you need a long run; manage wrap and bend radii to avoid kinks.
BELLA BAYS Copper Tubing 5 Ft — 1/4″ OD x 0.195″ ID
Specification: Annealed UNS C12200 Copper Tubing, 1/4″ OD x 0.195″ ID, 0.028″ wall, 5 ft length. seamless, coiled, and ASTM-B280 compliant. Nitrogen-charged treatment helps prevent oxidation, condensation, and impurities, extending the tubing’s service life in refrigeration and HVAC systems.
Best for: Compact projects, test setups, or small appliances where a short run is sufficient and flexibility is required to fit limited spaces.
Why selected: This length provides a convenient option for bench testing, prototypes, or repairs that don’t require a full-length coil.
Caution / Limitation: If your system demands a longer continuous run, this short coil will require more joints, which may increase potential leak points.
GOORY Copper Tubing 25 Ft — 1/4″ OD x 0.195″ ID
Specification: Annealed UNS C12200 Seamless Copper Tubing, 1/4″ OD x 0.195″ ID, 0.7mm wall, 25 ft. Compliant with ASTM-B280. The tube is nitrogen-filled to reduce impurities, resist oxidation and condensation, and tested for pressure. It demonstrates strong anti-rust and anti-corrosion performance, contributing to longer life in cooling devices and refrigerators.
Best for: Mid-length runs where continuity and reduced connection points matter, useful for professional installations or larger DIY setups.
Why selected: The 25 ft length offers a balanced choice between fewer joints and adequate reach for typical home HVAC or refrigeration tasks.
Caution / Limitation: Ensure adequate support to prevent bending under weight and heat exposure during installation.
TAUROX 50 Ft Copper Tubes — 1/4″ OD x 0.187″ ID
Specification: 50 ft length, 1/4″ OD x 0.187″ ID, 0.8 mm wall thickness. This 99.9% pure C12200 copper coil is compliant with ASTM B280, offering robust durability and a smooth surface for reliable sealing. It is nitrogen-charged to improve oxidation resistance and condensation control, aiding longer system life.
Best for: Longer projects or installations that require a substantial coil with minimal splices, ideal for professional HVAC or refrigeration builds.
Why selected: The longer coil reduces the number of connections, potentially lowering leak risk and easing installation in retrofit or new builds.
Caution / Limitation: The longer length may be less practical for ultra-tight spaces; plan routing before cutting to fit precisely.
Buying Guide: Key Considerations For 1/4″ Soft Copper Tubing
- Material quality and standard compliance: Look for UNS C12200 copper and ASTM-B280 compliance. These indicate consistent chemical composition, good thermal conductivity, and reliability in refrigeration and HVAC applications.
- Tube dimensions: OD and ID determine refrigerant capacity and pressure handling. Match your system’s specifications and confirm wall thickness compatibility with your bend radius and installation space.
- Length and coil type: Longer coils reduce joints but require more space and proper handling. Shorter coils offer flexibility in tight spaces but may need more fittings. Coil vs straight tube options influence ease of use for DIY projects.
- Manufacturing safeguards: Nitrogen-charged production helps minimize oxidation and impurities. This enhances durability and reduces risk of leaks over time, especially in warm environments.
- Flexibility and installation: High flexibility aids in tight bends and complicated routing. Consider the ease of bending by hand vs requiring tools, and protect from kinks to maintain flow.
