GOORY Copper Tubing 50 Ft — 5/8″ X 0.57″
Specification: Annealed UNS C12200 seamless copper, 5/8″ OD (15.88 mm) with 0.57″ ID (14.48 mm); wall thickness 0.028″ (0.7 mm); length 50 ft. This coil is designed for refrigeration and HVAC tasks requiring flexibility and reliable thermal performance.
Best for: DIY projects and small HVAC installations that need a long, continuous run without frequent joints. The tubing’s nitrogen-charged production helps minimize oxidation and impurities for improved longevity.
Why selected: It combines ASTM-B280 compliance with high corrosion resistance, enabling longer service life in condensers, air conditioners, and coolers. Suitable for semi-permanent installations where extended run lengths reduce fittings.
Caution: Some projects may require end-prep equipment or deburring tools due to seam-free construction. Ensure proper bending radius to avoid kinks in long runs.
GOORY Copper Tubing 20 Ft — 5/8″ X 0.57″
Specification: Annealed UNS C12200 seamless copper, 5/8″ OD × 0.57″ ID, wall thickness 0.028″ (0.7 mm), length 20 ft. COPPER is nitrogen-charged to resist oxidation and condensation, tested for pressure and durability.
Best for: Shorter runs or service calls where flexibility and quick fitting are prioritized. Suitable for repair work or new lines in compact appliances or units.
Why selected: Lightweight and easy to maneuver, ideal for tight spaces. This size reduces waste when you don’t need a full 50-foot coil.
Caution: Shorter tubing may require more fittings in a multi-segment install, increasing potential leak points if not properly sealed.
BELLA BAYS Copper Tubing 50 Ft — 5/8″ X 0.562″
Specification: Annealed UNS C12200 copper, 5/8″ OD × 0.562″ ID, wall thickness 0.031″ (0.8 mm), length 50 ft, seamless coil.
Best for: Professional or heavy-use DIY projects that require longer coils with robust thermal performance and corrosion resistance.
Why selected: Nitrogen-charged treatment helps reduce oxidation and condensation, extending life in air conditioners and refrigerators. The 50 ft length minimizes joint count in longer runs.
Caution: Ensure compatibility with fitment hardware designed for 0.562″ ID tubes to avoid sealing issues at joints.
BELLA BAYS Copper Tubing 20 Ft — 5/8″ X 0.562″
Specification: Annealed UNS C12200 copper, 5/8″ OD × 0.562″ ID, wall thickness 0.031″ (0.8 mm), length 20 ft, seamless coil.
Best for: Smaller installations or parts replacements where more manageable lengths are preferred without sacrificing performance.
Why selected: Conforms to ASTM-B280 with desirable flexibility and thermal efficiency. Suitable for compact systems in RVs, small appliances, or space-constrained HVAC units.
Caution: The 0.562″ ID dimension may require precise fittings; measure inlet/outlet diameters before purchase to ensure a proper fit.
ELECTRAPICK Copper Tubing 50 Ft — 5/8″ X 9/16″
Specification: 5/8″ OD × 9/16″ ID (15.88 × 14.48 mm); wall thickness 0.028″ (0.7 mm); length 50 ft. Seamless, round copper tube designed for refrigeration and HVAC.
Best for: Projects requiring high heat transfer and durability with a slightly tighter ID than standard to optimize refrigerant flow.
Why selected: High-quality C12200 copper offers strong corrosion resistance and easy machinability. The slightly smaller ID can help match certain system specs and reduce refrigerant volume requirements.
Caution: The 9/16″ ID dimension may not fit standard fittings intended for 5/8″ ID tubes; verify compatibility before installation.
Buying Guide
What to consider when choosing 5/8 refrigeration tubing
- Length needs: Decide between coils (50 ft) or shorter segments (10–20 ft) based on your project footprint and fitting availability.
- Diameter compatibility: Check exact ID and OD measurements to ensure it matches the system connections and fittings.
- Material standard: Confirm UNS C12200 copper and ASTM B280 compliance for reliability in HVAC and refrigeration environments.
- Wall thickness: 0.028–0.031 inches offers a balance between flexibility and strength; thicker walls resist damage but are less flexible.
- Production quality: Nitrogen-charged treatment helps reduce impurities and oxidation, extending service life in condensers and coolers.
- Flexibility and installation: Seamless, soft coils are easier to bend for complex runs but require careful handling to avoid kinks.
- Application fit: Some products have slightly different ID (9/16″ vs 0.562″), which may affect compatibility with existing components.
Frequently Asked Questions
- What does 5/8″ OD mean in refrigeration tubing?
It refers to the outer diameter of the tube, which determines compatibility with fittings and clamps. - Is nitrogen charging common for copper tubing?
Yes, nitrogen charging reduces impurities and oxidation during manufacturing, increasing durability. - Which length should I choose for a DIY project?
Choose length based on the planned run length and how many joints you want to minimize. - Are these tubes suitable for outdoor use?
Copper tubes with corrosion resistance perform well in outdoor environments, but protect fittings from weather exposure. - What should I avoid when installing 5/8″ copper tubing?
Avoid over-bending and kinks; use proper bending tools and follow manufacturer radius recommendations. - Can I mix 9/16″ ID with 5/8″ OD tubing in a single system?
Compatibility depends on end fittings and system design; verify with a qualified HVAC technician.
