GOORY Copper Tubing 50 Ft — 5/8 in OD
Specification: Annealed UNS C12200 seamless copper, 5/8″ OD x 0.57″ ID, wall 0.028″ (0.7 mm), length 50 ft. This coil meets ASTM B280 and offers excellent flexibility for easy installation in HVAC and refrigeration lines.
Best for: Professionals installing longer refrigerant runs where smooth bending and good thermal performance are required. The nitrogen-filled production helps reduce impurities and oxidation, extending service life in air conditioners and refrigerators.
Limitations: Slightly longer length may require careful handling on smaller workspaces; ensure you have the right bending tools to maintain the seamless integrity.
BELLA BAYS Copper Tubing 50 Ft — 5/8 in OD
Specification: UNS C12200, 5/8″ OD x 0.562″ ID, wall 0.031″ (0.8 mm), 50 ft coil, seamless. Meets ASTM-B280 with nitrogen treatment to resist oxidation and condensation.
Best for: Projects requiring strong durability and reliable performance over longer runs in traditional HVAC setups. The longer lifespan comes from the nitrogen-charged process that mitigates oxidation.
Limitations: Slightly thicker wall than some 0.028″ options; consider tool compatibility for tighter bends.
BELLA BAYS Copper Tubing 5 Ft — 5/8 in OD
Specification: UNS C12200, 5/8″ OD x 0.562″ ID, 0.031″ wall, 5 ft coil. Seamless, nitrogen-charged for oxidation resistance and long-term durability.
Best for: Small upgrades or repairs where a short, flexible coil is preferred for convenient handling and quick installations.
Limitations: Short length may require splicing for longer runs; plan for joints or fittings accordingly.
BELLA BAYS Copper Tubing 50 Ft — 5/8 in OD
Specification: UNS C12200, 5/8″ OD x 0.562″ ID, 0.031″ wall, 50 ft coil. Seamless and nitrogen-treated to reduce oxidation and condensation risk.
Best for: General-purpose HVAC refrigeration installations needing a robust, long coil with consistent performance.
Limitations: Slightly larger ID tolerance may affect precise fit in very tight assemblies; verify compatible fittings before purchase.
GOORY Copper Tubing 20 Ft — 5/8 in OD
Specification: 5/8″ OD x 0.57″ ID, 0.028″ wall, 20 ft, seamless nitrogen-treated. Matches ASTM B280 with strong flexibility for installations requiring shorter coils.
Best for: DIY projects or compact systems where a moderate-length coil is needed and bending ease matters.
Limitations: Shorter length means more joints if multiple runs are required; plan for fittings and flow path accordingly.
ELECTRAPICK Copper Tubing 50 Ft — 5/8 in OD
Specification: 5/8″ OD x 9/16″ ID, 0.028″ wall, 50 ft coil. Soft seamless copper designed for easy fabrication and reliable thermal transfer.
Best for: Air conditioning and refrigeration setups requiring high corrosion resistance and straightforward threading or bending.
Limitations: ID is slightly smaller than some 9/16″ options; verify clearance for fittings and ports.
ICS Industries 50 Ft Copper Tubing
Specification: 5/8″ OD Copper Refrigeration ACR tubing, 50 ft, seamless. Designed for refrigeration applications with standard ACR dimensions.
Best for: Projects requiring a straightforward, reliable coil that aligns with common ACR fittings and expectations.
Limitations: Limited product detail may require careful fitment checks for niche systems.
Buying Guide
What to consider when choosing 5/8″ copper tubing:
- Length and layout: Determine total run length and required coil counts to minimize joints and pressure losses.
- Wall thickness: 0.028″ to 0.031″ walls balance strength and flexibility; thicker walls offer durability in high-pressure systems.
- Material grade: UNS C12200 copper provides good thermal conductivity and corrosion resistance; ensure it complies with ASTM B280.
- Coil condition: Nitrogen charging reduces oxidation and condensation; this helps extend life in HVAC and refrigeration.
- Fittings and compatibility: Confirm ID size (9/16″ vs 0.57″) and availability of compatible fittings for your system.
- Handling and tooling: Softer, annealed copper bends easily; have proper coping and rolling tools to avoid kinks.
- Environment and durability: For outdoor or humid environments, corrosion resistance is critical; consider protective routing measures.
Frequently Asked Questions
- What is the difference between 0.57″ ID and 0.562″ ID copper tubing?
Answer: The ID variation is minor and mainly affects fit with certain fittings; verify the port size on your equipment. - Is nitrogen charging important for HVAC copper tubing?
