GOORY Copper Tubing 1/4″ 10 Ft – Pure C12200 ACR Tube
Specification: Annealed UNS C12200 seamless copper tubing, 1/4″ OD x 0.195″ ID, wall 0.028″, 10 ft long. This tube is designed for refrigeration systems and adheres to ASTM B280 standards. It offers good flexibility for installations, high thermal conductivity, and strong corrosion resistance. The nitrogen-filled production process reduces impurities and helps ensure longevity in air conditioners and refrigerators.
Best for: DIY enthusiasts and professionals performing short runs or coil replacements in compact spaces where precise fit matters. It’s especially suitable for small-capacity systems or secondary cooling loops. Limitation: shorter length means more joins and fittings for longer installations, which can increase setup time.
GOORY Copper Tubing 3/8″ 50 Ft – ACR Tube
Specification: UNS C12200 seamless tubing, 3/8″ OD x 0.328″ ID, 0.024″ wall, 50 ft. This tubing is flexible for easy installation and provides strong thermal conductivity with corrosion resistance. It’s nitrogen-charged to reduce impurities and endure pressure testing, supporting longer life in air conditioners and refrigerators.
Best for: Projects requiring longer horizontal runs or medium-to-large HVAC loops. Better for installations that need a balance of rigidity and bendability. Caution: ensure proper support and avoiding over-bending to prevent kinks in longer runs.
BELLA BAYS Copper Tubing 3/4″ 5 ft – Seamless ACR Tube
Specification: UNS C12200 copper, 3/4″ OD x 0.687″ ID, 0.8 mm wall, 5 ft coil. This seamless tubing adheres to ASTM B280 and is noted for flexibility, thermal conductivity, and durability. Nitrogen treatment minimizes oxidation and impurities for extended service life in HVAC systems.
Best for: Higher-flow segments or compact coils that need a larger diameter to reduce velocity. Choose this if your system demands robust capacity in a short coil. Limitation: shorter length may necessitate more joints for large configurations, potentially increasing leak points if not properly brazed.
GOORY Copper Tubing 5/8″ 50 Ft – ACR Tube
Specification: UNS C12200 seamless copper, 5/8″ OD x 0.57″ ID, 0.028″ wall, 50 ft. It combines flexibility with durable construction and complies with ASTM B280. Nitrogen charging reduces oxidation and impurities, contributing to extended life in air conditioning and refrigeration equipment.
Best for: Mid-length to long runs with a need for sturdy tubing able to handle higher refrigerant flow. Better for installations needing dependable performance across diverse temperatures. Limitation: heavier and larger diameter may require stronger mounting or supports in tight spaces.
BELLA BAYS Copper Tubing 1/4″ 10 Ft – Seamless ACR Tube
Specification: UNS C12200 copper, 1/4″ OD x 0.195″ ID, 0.028″ wall, 10 ft coil. Fabricated to ASTM B280, the tubing remains flexible, with excellent thermal conductivity and corrosion resistance. Nitrogen-filled production helps minimize oxidation and impurities.
Best for: Short, tight routes in small appliances or compact refrigeration units. Advantage: easy to handle and bend. Limitation: limited length requires more joints for longer installations, potentially increasing assembly time and leak risk if joints are not well brazed.
Buying Guide: Copper Tubing For Refrigeration
- Material and standards: Look for UNS C12200 copper, seamless tubes that meet ASTM B280 for reliable refrigeration performance and corrosion resistance.
- Diameter and wall thickness: OD and ID determine flow capacity and fit. Thicker walls offer durability but reduce flexibility; choose according to system pressure and bend requirements.
- Length and sections: Short coils are easy to route in tight spaces; longer lengths reduce the number of joints but require careful handling to prevent kinks.
- Nitrogen charging: Tubing nitrogen-filled during production minimizes oxidation and impurities, extending service life in HVAC equipment.
- Flexibility vs. rigidity: Softer, annealed tubing is easier to bend for complex runs but may require more supports to prevent sagging.
- Compatibility and safety: Ensure fittings, couplings, and brazing materials are compatible with the copper tubing and refrigerant type used in your system.
- Installation considerations: Plan joints and bends to minimize flow resistance and leakage risk. Use proper insulation if runs are exposed to ambient conditions.
FAQ
- What copper tube is best for refrigeration? UNS C12200 seamless copper tubes that meet ASTM B280 are widely recommended for their balance of conductivity, flexibility, and durability.
- Why nitrogen-filled tubing matters? Nitrogen charging reduces impurities and oxidation, increasing the tubing’s lifespan in HVAC and refrigeration systems.
- What diameter should I choose? Select OD and ID based on desired refrigerant flow and fitting compatibility. Larger diameters suit higher flows; smaller diameters fit tight spaces.
- How long should tubing be? Match length to your installation layout. Longer runs reduce joints but require careful handling to avoid kinks.
- Are there safety considerations with copper tubing? Use appropriate brazing equipment, protect against leaks, and ensure fittings are properly sealed to avoid refrigerant loss.
- Can I reuse tubing? Reuse is possible if there are no signs of damage, corrosion, or deformation and joints are thoroughly cleaned and brazed again.
