GOORY Copper Tubing 1/4″ OD x 0.195″ ID — 10 ft Coil
Specification: Annealed UNS C12200 seamless copper tubing, 1/4″ OD x 0.195″ ID, wall 0.028″, 10 ft. It is compliant with ASTM-B280 and offers good flexibility for easy installation. For refrigeration systems, this coil provides strong thermal performance and corrosion resistance. It is nitrogen-filled during production to minimize impurities and oxidation, supporting longer service life. Best for tight fridge connections or compact refrigeration layouts where a small-diameter copper line is required.
Best for: DIYers installing compact fridge lines and technicians needing a small, flexible coil. Caution: Shorter length means more joints; plan for the run to minimize extra fittings.
BELLA BAYS Copper Tubing 1/4″ OD — 10 ft
Specification: Annealed UNS C12200 copper, 1/4″ OD x 0.195″ ID, 0.7 mm wall, 10 ft seamless coil. Conforms to ASTM-B280, offering reliable flexibility, high thermal conductivity, and durability. The nitrogen-charged treatment reduces oxidation and condensation, contributing to longer equipment life for air conditioners, coolers, and refrigerators.
Best for: Users needing a quick, reliable 10-foot run with robust corrosion resistance. Caution: For longer spans, consider pairing with a second coil to minimize joints and potential leaks.
GOORY Copper Tubing 3/8″ OD — 50 ft
Specification: Annealed UNS C12200 seamless copper tubing, 3/8″ OD x 0.328″ ID, wall 0.024″, 50 ft. This longer coil supports larger or multiple refrigerant runs with continued flexibility and corrosion resistance. Nitrogen-filled production minimizes impurities and oxidation, enhancing longevity in HVAC systems and refrigerators.
Best for: Projects requiring longer continuous runs or shared lines between units. Caution: Larger diameter requires compatible fittings and tools; ensure system compatibility before installation.
BELLA BAYS Copper Tubing 1/4″ OD — 25 ft
Specification: 1/4″ OD x 0.195″ ID, 0.7 mm wall, 25 ft seamless coil. Meets ASTM-B280, with nitrogen-treated copper for reduced oxidation and longer service life. Flexible coil aids in routing around tight spaces in HVAC or refrigeration setups.
Best for: Medium-length runs with good balance of handling and durability. Caution: Verify overall run length to minimize joints for leak prevention.
Supplying Demand CIM25 Copper Line Kit — 25 ft
Kit includes 25 feet of 1/4″ copper tubing, a self-tapping saddle valve, and a compression fitting. The valve is designed for connecting to a water supply line for ice maker installation. Copper tubing is standard for refrigerant lines and is compatible with common ice maker connections.
Best for: Quick ice-maker hookups and retrofit projects. Caution: Ensure compatibility with your existing water supply and valve requirements; use proper shutoff valves during installation.
Buying Guide: Key Purchase Considerations
Material quality and spec compliance matter more than coil length alone. Look for copper tubing that is UNS C12200, nitrogen-charged, and ASTM-B280 compliant for reliable corrosion resistance and performance in refrigeration systems.
Size and compatibility are essential. The 1/4″ OD coils fit many standard ice maker and fridge connections, while 3/8″ OD supports larger or multiple lines.
Length should reflect your project—short runs minimize joints, but longer coils reduce the number of connections and potential leaks. Always plan fittings and adapters ahead of time.
Installation considerations include flexibility for routing, the presence of protective coatings or treatments, and compatibility with existing fittings and valves. Use proper tools and follow local codes for safe, leak-free connections.
Kit contents, such as saddle valves and compression fittings, can simplify installation but require careful handling to avoid leaks. When replacing lines, inspect fittings, seals, and end connections for corrosion or wear.
FAQ
- What copper size is best for a typical fridge ice maker? The common size is 1/4″ outer diameter (OD) copper tubing, which fits many standard ice maker valves and fridge connections.
- Is nitrogen-filled copper better for refrigerators? Yes. Nitrogen-filled copper reduces oxide formation and impurities, which can extend the tubing’s life and reduce corrosion.
- Can I use a longer copper coil for my fridge? Yes, a longer coil is useful for longer runs or multiple connections, but ensure you have compatible fittings and adequate space for routing.
- Do these tubes meet industry standards? Look for ASTM-B280 compliance and UNS C12200 designation to ensure quality and compatibility.
- Should I buy a full kit or individual coils? If you’re adding an ice maker, a kit with a saddle valve can speed installation; for straightforward runs, individual coils provide more flexibility.
- What should I check before installation? Inspect the ends for clean, true cuts, ensure fittings match standard compression sizes, and verify system shutoffs are accessible before work.
