XIFOWE 99.9% Copper Tube — 5 Ft Coil
XIFOWE offers a soft, seamless copper tube designed for refrigeration and HVAC work. The tube has a 1/4″ outer diameter and 3/16″ inner diameter with a wall thickness around 0.8 mm. Manufactured through continuous casting and rolling, it adheres to ASTM-B280 standards, delivering solid thermal conductivity and corrosion resistance. The 5-foot length is suitable for small projects and DIY runs, with the note that actual length may be slightly longer than 10 feet when measured along the coil. This tube provides good machinability and durability in high-pressure environments.
SHASKOKOEN Pure Copper Tubing — 5 Ft
SHASKOKOEN’s copper tubing is 1/8″ outer diameter with a 1/12″ inner diameter, in a 5-foot length. The soft, seamless copper surface supports good extensibility and conductivity. Though natural oxidation and slight discoloration can occur with copper, polishing is possible to restore appearance. The tube’s copper composition provides strong heat transfer and is well-suited for refrigeration piping in appliances and DIY projects, including air conditioners and freezers. The product emphasizes smooth fabrication and reliable performance in typical refrigeration tasks.
uxcell Refrigeration Tubing — 6.5 Ft
uxcell’s refrigeration tubing measures 1/8″ outer diameter with a 5/64″ inner diameter and spans 6.5 feet. It is designed for efficient heat dissipation and reliable refrigeration performance, suitable for refrigerators, freezers, and air conditioning systems. The copper material provides resistance to oxidation and corrosion, and the tube’s hollow construction improves heat transfer. It is a practical option for DIY projects requiring compact, flexible copper piping with predictable refrigerant compatibility.
Eoiips Copper Tube — 4.92 Ft
Eoiips presents a 1/4″ outer diameter by 3/16″ inner diameter seamless copper tube, approximately 4.92 feet in length. The soft copper material provides good ductility and thermal conductivity, with a smooth surface that facilitates easy bending and shaping for refrigeration installations. This product emphasizes flexibility and ease of work in varied hot and cold conditions, making it suitable for projects where routing around tight spaces is necessary and long-term thermal performance is important.
GOORY Copper Tubing — 10 Ft Coil
GOORY’s 1/4″ OD copper tubing features a 0.195″ inner diameter and a 10-foot coil with a 0.028″ wall thickness. It is made from annealed UNS C12200 copper and meets ASTM-B280, ensuring robust thermal conductivity and durability for refrigeration and HVAC applications. The tubing’s nitrogen charged treatment helps resist oxidation and condensation, extending service life in challenging operating conditions. Its seamless coil design simplifies handling and installation in longer runs.
Buying Guide: Copper Tubing For Refrigeration
Key considerations when selecting copper tubing for refrigeration systems include material grade, diameter and wall thickness, flexibility, and compliance with standards. Copper tubes labeled UNS C12200 are common in HVAC for their combination of thermal performance and durability. Inner diameter choices affect refrigerant flow and pressure drop, so match OD/ID to your system’s specifications and fittings.
Installation environment and system type also matter. Soft, seamless tubes are easier to bend for retrofit projects and tight spaces, while thicker walls provide added strength in high-pressure lines. Surface finish and oxidation resistance influence long-term performance; some copper tubes are treated to reduce oxidation and condensation risks, which can improve lifespan in humid climates.
Length and coil design impact handling and layout. Shorter lengths reduce waste in small upgrades, while longer coils minimize joins in longer runs. Always verify compatibility with your refrigerant type, compressor, and match with standard fittings (e.g., 1/4″ or 3/8″ lines).
Quality and price considerations are balanced by the tube’s application. For DIY projects, a versatile, easily bendable tube with good corrosion resistance is often preferred. For professional installations, select tubing that strictly adheres to ASTM-B280 and other applicable standards to ensure system reliability and warranty compliance.
Maintenance and care tips: Handle copper tubing carefully to avoid kinks; use proper cutters and deburring tools; protect from excessive heat during cutting; store coils away from moisture to limit oxidation; and verify leak integrity after installation with appropriate refrigerant charging procedures.
In sum, the right copper pipe for refrigeration should provide dependable thermal performance, durability against oxidation, and compatibility with your system’s fittings. The five options above cover a range of sizes, flexibility, and use cases—from DIY coil runs to professional HVAC installations—helping you select copper tubing that aligns with your project goals and environment.
