GOORY Copper Tubing 10 Ft – 1/4″ O.D. 0.195″ I.D.

Specification: Annealed UNS C12200 seamless copper tube, 1/4″ OD, 0.195″ ID, wall 0.028″, length 10 ft. Fully compliant with ASTM B280. Features high flexibility, strong thermal conductivity, and corrosion resistance. Nitrogen-filled production minimizes impurities and reduces oxidation risk.
Best for: DIYers performing short, straightforward HVAC tasks or condensate line replacements where a compact coil is enough. Limitation: shorter length may require more joints for long runs.
BELLA BAYS Copper Tubing 25 Ft – 1/4″ OD x 0.195″ ID

Specification: UNS C12200 copper, seamless coil, 1/4″ OD × 0.195″ ID, wall 0.028″, length 25 ft. Nitrogen-charged for oxidation resistance, tested for pressure, and designed for durability in HVAC and refrigeration. ASTM-B280 compliant.
Best for: Projects requiring longer coil length with consistent performance and easier handling. Caution: ensure correct bend radii to avoid kinking in longer runs.
Tynulox Copper Tubing 3 FT – 1/4″ OD × 3/16″ ID

Specification: 3 ft length, 1/4″ OD × 3/16″ ID, 0.675 mm wall. 99.9% copper provides strong heat transfer and corrosion resistance. Suitable for refrigeration tubing in refrigerators and air conditioners; can be bent into elbows or shapes for crafts and jewelry applications.
Best for: Short runs or custom shapes where precision is important. Limitation: not ideal for long continuous runs due to limited length.
BELLA BAYS Copper Tubing 50 Ft – 1/4″ OD x 0.187″ ID

Specification: UNS C12200 seamless coil, 1/4″ OD × 0.187″ ID, wall 0.8 mm, length 50 ft. Nitrogen-filled for oxidation resistance, pressure-tested, compatible with various traditional and modern HVAC applications.
Best for: Medium to large installations where a longer continuous coil reduces joints. Limitation: slightly narrower ID than some alternatives may constrain certain fittings.
GOORY Copper Tubing 50 Ft – 1/4″ OD x 0.187″ ID

Specification: UNS C12200 seamless 1/4″ OD × 0.187″ ID, wall 0.031″, length 50 ft. ASTM-B280 compliant, flexible tubing with excellent thermal conductivity and corrosion resistance. nitrogen-charged to limit oxidation and condensation.
Best for: Versatile coil for mid-to-long runs in HVAC and refrigeration projects. Limitation: longer coils require careful handling to prevent kinking during installation.
Buying Guide: Key Purchase Considerations
- Length and coil format: Choose length to minimize joints. Longer coils reduce connections but can be harder to route.
- Wall thickness and ID: Thicker walls improve durability; slightly larger ID can improve flow but may affect fittings.
- Alloy and standards: Look for UNS C12200 copper and ASTM-B280 compliance for compatibility with HVAC and refrigeration systems.
- Manufacturing quality: Nitrogen-charged production reduces oxidation; select tubes tested for pressure and impurities.
- Flexibility and bending: Ensure the tubing can be bent to fit corners without kinking; some products are explicitly coil-friendly for easy shaping.
- Best-for scenarios: Short runs vs. long runs, DIY repairs vs. professional installations, and compatibility with standard fittings.
- Storage and handling: Keep coils away from moisture and oxidation-prone environments; use proper supports during installation.
FAQ
- What is the typical ID for 1/4″ copper line used in HVAC?
– Common IDs include 0.195″ and 0.187″, depending on the product and application. - Is nitrogen charging important for copper tubing?
– Yes, nitrogen charging helps prevent oxidation and impurities, extending service life. - Can 1/4″ copper tubing be bent easily for tight corners?
– Most options are designed for easy bending, but avoid sharp bends to prevent kinking. - Which length should I choose for a home HVAC repair?
– For short runs, 5–10 ft coils are often sufficient; longer runs reduce joints but require careful handling. - Are all these tubes compatible with standard refrigeration fittings?
– Yes, these tubes are selected to be compatible with common HVAC and refrigeration fittings under ASTM-B280.
