Copper Tubing 3/4 in OD x 0.687 in ID x 5 ft - Reliable HVAC & DIY

In this review the BELLA BAYS copper tubing is evaluated for HVAC, refrigeration and DIY use; the bottom line is that it is a reliable, easy-to-work-with refrigeration tube that serves installers and hobbyists who need a short, seamless coil of pure copper. The single biggest reason to buy is the material quality: annealed UNS C12200 copper meeting ASTM-B280-style refrigeration expectations, which gives excellent thermal conductivity and corrosion resistance for condenser, air conditioner, or refrigerator lines. For anyone needing a 5 ft coil of soft, bendable copper tubing, this is a practical choice.

Key Features

• Material and spec: Annealed UNS C12200 copper tubing provides consistent thermal conductivity and meets the needs of refrigeration and ACR applications.
• Dimensions: The 3/4 in outside diameter with 0.687 in inside diameter and 0.8 mm wall thickness fits common HVAC and refrigeration fittings and keeps flow capacity predictable.
• Seamless coil: Supplied in a soft coil and seamless form, it is easy to bend into place without kinking for compact installations or repairs.
• Nitrogen charged treatment: The nitrogen treatment reduces oxidation and impurities so the tubing resists corrosion and supports longer equipment life.
• Ease of use: Smooth walls and soft annealed temper make cutting, bending and joining by sweating or flare fittings straightforward for technicians and DIYers.
• Versatile application: Suitable for refrigeration, HVAC, ACR tubing and a range of crafts or thermal-conductivity uses where small runs of copper are needed.

Who It's For

The tubing is aimed at HVAC technicians, refrigeration service professionals and experienced DIYers who need a short run of quality refrigeration copper that is easy to bend and join. It is particularly useful for repairs, prototyping, or installations where a 5 ft length and the convenience of a soft coil are sufficient.

Those who need long, continuous lengths for large installations or who require pre-flared ends and fittings included should look elsewhere; this product is a raw coil intended for users comfortable cutting and assembling their own joints.

Pros & Cons

Pros

• High-quality UNS C12200 copper offers strong thermal performance and corrosion resistance for refrigeration use.
• Seamless, annealed construction in a soft coil allows easy bending and shaping without special equipment.
• Nitrogen charged treatment and pressure testing reduce oxidation and help extend system life.
• Good value for short runs and DIY projects where precision bending matters.

Cons

• At 5 ft length, it is best suited to small repairs or projects rather than long plumbing runs.
• Some users reported mixed impressions of flatness on bends, so careful forming may be required for certain tight radii.

Frequently Asked Questions

Is this tubing suitable for refrigeration lines?
Yes. The annealed UNS C12200 copper and seamless form are intended for refrigeration and ACR use and conform to expected ASTM-B280-style performance.

Can it be bent and flared on site?
Yes. The soft, annealed coil bends easily and can be cut and assembled with sweating or flare fittings for on-site work.

Will one 5 ft coil work for large HVAC runs?
No. The 5 ft length is best for repairs, short connections or prototype work; larger installations will require longer runs or multiple sections joined together.
