BELLA BAYS Copper Tubing — 50 ft
Specification: Annealed UNS C12200, 7/8″ OD x 0.796″ ID, wall 0.039″ (1.0 mm), length 50 ft, seamless coil.
Best for: Professionals and DIYers tackling longer refrigeration or HVAC runs where flexibility and durability are essential. The larger coil minimizes re-joins and aids in smoother routing.
Why selected: It adheres to ASTM-B280 refrigeration copper standards and offers good thermal conductivity with corrosion resistance. Nitrogen charged treatment contributes to oxidation resistance for longer service life.
Caution: Large coils can be cumbersome to maneuver in tight spaces; plan bends and supports carefully to avoid kinks.
BELLA BAYS Copper Tubing — 25 ft
Specification: 7/8″ OD x 0.796″ ID, wall 0.039″, length 25 ft, seamless coil.
Best for: Mid-size refrigeration or HVAC projects where users need a balance between length and handling ease. Suitable for modular installations and moderate runs.
Why selected: Consistent C12200 copper quality with ASTM-B280 compliance and nitrogen treatment for oxidation resistance. Durable and easy to bend with controlled flexibility.
Caution: Shorter length means more fittings and potential joints; ensure fittings are compatible with the 7/8″ OD tube.
BELLA BAYS Copper Tubing — 10 ft
Specification: 7/8″ OD x 0.796″ ID, length 10 ft, seamless coil.
Best for: Small projects, service calls, or tight spaces where short, flexible runs are needed. Great as a prep tubing for quick setups.
Why selected: Consistent copper grade with readiness for quick installation. Nitrogen charged treatment supports longevity in varied environments.
Caution: Shorter length increases the number of joints; plan to minimize fittings to reduce leak risk.
GOORY Copper Tubing — 50 ft
Specification: 7/8″ OD x 0.796″ ID, wall 0.039″ (1 mm), length 50 ft.
Best for: Projects demanding good flow attributes and reliable performance across longer runs. Suitable for residential and commercial HVAC setups.
Why selected: UNS C12200 copper with ASTM-B280 compliance. Nitrogen charge and thorough testing provide strong resistance to oxidation and condensation.
Caution: As with other coils, ensure adequate straightening before bending to prevent deformation.
ELECTRAPICK Copper Tubing — 50 ft
Specification: 7/8″ OD x 0.80″ ID (22.23×20.22 mm), 50 ft, wall 1 mm (0.039″), seamless coil.
Best for: HVAC and refrigeration projects requiring smooth interior surfaces and easy installation, with consistent heat transfer characteristics.
Why selected: High-quality C12200 copper with corrosion resistance and good thermal conductivity. The smooth interior reduces flow resistance and potential buildup.
Caution: Slightly wider ID tolerance may affect fittings; verify compatibility with existing lines and connectors.
Buying Guide
What to consider when choosing 7/8″ ACR copper tubing
- Length vs. project scope: Longer coils reduce joints but can be harder to maneuver in tight spaces. Shorter lengths offer flexibility for precise routing.
- Material grade and standard compliance: Look for UNS C12200 copper and ASTM-B280 refrigeration standards for reliable performance and compatibility.
- Wall thickness and ID: A thicker wall increases durability; ensure the ID matches your fittings and expected flow rates.
- Treatment and oxidation resistance: Nitrogen charged treatment helps prevent oxidation, extending service life in condenser and coil applications.
- Handling and installation: Some tubes are easier to bend; consider your toolset and skill level for seamless installation.
- Application fit: Choose based on whether you need long runs (50 ft coils) or quick, compact installations (10–25 ft coils).
Comparison at a glance
- Best for long runs: 50 ft coils from BELLA BAYS or GOORY.
- Better for mid-size jobs: 25 ft BELLA BAYS.
- Choose this if you need quick, small installs: 10 ft BELLA BAYS.
- Durability and corrosion resistance: All options use UNS C12200 copper; nitrogen treatment enhances longevity.
- Important caveat: More joints increase potential leak points; plan fittings accordingly.
FAQs
- What does 7/8″ ACR copper tubing mean?
– It refers to the outer diameter of the copper tube used in air conditioning and refrigeration applications, with a typical inner diameter slightly smaller for flow needs. - Is nitrogen charging common and why does it matter?
– Nitrogen charging helps prevent oxidation and impurities, contributing to longer service life in condenser and coil systems. - What should I consider when choosing length?
– Assess the layout, required fittings, and ease of handling. Longer coils reduce joints but may be harder to route in confined spaces. - Are all 7/8″ tubes compatible with standard fittings?
– Most are designed to match common 7/8″ plumbing and HVAC fittings, but always verify OD, ID, and thread/flare compatibility with your connectors. - What is ASTM-B280?
– It is a standard specification for seamless or welded copper refrigeration tubes used in HVAC and refrigeration systems. - Can these tubes be bent by hand?
– They are flexible but require proper bending tools and techniques to avoid kinks and maintain smooth interior surfaces.
