uxcell Copper Round Tube, 2mm OD

- Features: Durable copper tube with lightweight, high strength, good thermal conductivity, corrosion resistance, high-temperature resistance, ductility, and weather resistance.
- Application: Suitable for machinery, DIY projects, hobbies, crafts, models, frames, industrial uses, and gardening products.
- Weldable & Cuttable: Can be welded and cut to different lengths with appropriate equipment.
Best for precision, small-scale projects and model work where compact tubing is needed. Limitations: very small diameter may limit fluid transport or pressure scenarios; ensure compatible fittings for higher-pressure applications.
uxcell Copper Round Tube, 15mm OD

- Features: Copper tubing with lightweight strength, good thermal conductivity, corrosion resistance, and high-temperature resistance.
- Application: Applicable to machinery, DIY projects, crafts, frames, and industrial uses.
- Weldable & Cuttable: Suitable for customization with proper tools.
Best for projects needing a moderate bore for gas or liquid transport in a compact footprint. Caution: larger diameter requires compatible fittings and more robust tools for cutting and welding.
BELLA BAYS Copper Tubing 1/2″ OD

- Specification: Annealed UNS C12200, 1/2″ OD x 0.445″ ID, 0.028″ wall, 5 ft coil; seamless.
- Work Performance: Flexible with excellent thermal conductivity and corrosion resistance; adheres to ASTM-B280; suitable for HVAC and refrigeration.
- Longer Lifespan: Nitrogen charged treatment reduces oxidation and condensation, extending life in condensers, air conditioners, and refrigerators.
Choose this if you need a versatile, longer coil for HVAC refrigerant lines or DIY cooling projects. Limitation: coil form may require straightening for some installations; ensure proper shaping tools.
uxcell Refrigeration Tubing, 1/8″ OD

- Feature: 1/8″ OD x 5/64″ ID, 16 Ft length; 3mm outer diameter, 2mm inner diameter.
- Application: High refrigeration efficiency; suited for refrigerators, freezers, and air conditioners.
- Material: Copper, with high temperature and corrosion resistance; durable in low-temperature environments.
Best for compact refrigeration circuits where good heat transfer and flexible routing are needed. Limitation: very small diameter may restrict fluid flow in high-demand systems.
Kraftex Tube Cutter

- Purpose: Designed to cut copper, steel, stainless steel, aluminum, PVC, and brass tubes; compact for tight spaces.
- Use: Helpful for plumbers, electricians, and mechanics tackling small to mid-size copper piping tasks.
- Limitation: Not intended for PVC pipes in some cases; verify compatibility with the exact material.
Best for quick, straight cuts in copper piping within restricted spaces. Choose this if you need a versatile cutter for mixed materials; avoid if you exclusively work with PVC-only systems.
1 Inch Type L Copper Pipe

- Specification: ASTM B88 certified, heavy-wall Type L copper for water, HVAC, and gas distribution; 1″ OD with compatible fittings.
- Use: Suitable for potable water lines, refrigeration, chilled water, and vacuum systems; handles hot and cold up to high temperatures.
- Compatibility: Works with standard fittings and modern press or solder methods.
Best for heavier-duty residential and commercial piping where reliability and standard fittings matter. Limitation: larger diameter can be less flexible for tight routing; plan fittings accordingly.
Buying Guide
What should you consider when selecting PVC coated copper tube products?
- Size and wall thickness: Choose OD and wall thickness based on pressure, flow needs, and space constraints.
- Application type: HVAC, refrigeration, or potable water require different copper grades and coatings; verify compatibility with your system.
- Coating and protection: PVC coating or seamless copper with protective treatments helps resist corrosion; consider environment and exposure conditions.
- Fabrication needs: Check weldability, solderability, and cutability for your preferred fabrication method.
- Working conditions: Temperature range and exposure to elements influence performance and lifespan; nitrogen/chromium treatments may extend life in condensers and coolers.
- Fittings and compatibility: Ensure that chosen tubes align with standard fittings or press systems you plan to use.
Frequently Asked Questions
- What is PVC-coated copper tube used for?
- Can copper tubes be welded and cut easily?
- Which size is best for HVAC refrigerant lines?
- Is Type L copper better than other types?
- Do all copper tubes require special coatings for outdoor use?
- What should I avoid when selecting copper tubing for DIY projects?
PVC-coated copper tube is used in plumbing, HVAC, refrigeration, and DIY projects where corrosion resistance and ease of handling are important, while maintaining good thermal properties.
Yes. Many copper tubes are weldable and cuttable with proper tools, though exact methods depend on diameter and wall thickness.
Coils and small to mid-diameter tubes (such as 1/2″ to 3/8″ sizes) are common for refrigerant lines, depending on system design and refrigerant requirements.
Type L copper is a balanced choice offering strength and durability for water and HVAC systems, with broad compatibility with fittings and soldering.
Outdoor exposure may benefit from coatings or protective measures, especially in humid or industrial environments; select products designed for weather resistance.
Avoid tubes with incompatible coatings or diameters for your fittings and tools; verify pressure ratings and fabrication compatibility before purchasing.
