Pure Copper 110 Soft Copper Tubing — Annealed Coil

Flexible, seamless soft copper tubing coil, annealed for easy bending around corners, sold by the meter or in roll lengths for HVAC, gas, and water runs.

Soft annealed copper tubing coil — also called soft copper coil, flexible copper tubing, annealed copper coil, or copper coil tubing — is seamless 99.9% pure copper 110 tube that has been annealed (softened) and wound into a coil. Where rigid straight tube must be pre-bent and joined, soft copper tubing bends by hand or with a bender to follow walls, cabinets, and equipment frames, so installers can run long continuous lines with far fewer joints. It is the standard flexible copper coil for HVAC line sets, refrigerant and air-conditioning connections, gas and water supply, heat pumps, appliances, and repair and retrofit work across the United States.

The coil is selected by outer diameter (OD) with the standard wall, and can be supplied cut by the meter or foot, or in continuous roll lengths, so buyers receive exactly the length of flexible copper tubing their installation needs without waste or extra connections.

What Is Soft Annealed Copper Tubing?

Pure copper 110 is commercial-grade 99.9% pure copper valued for high thermal and electrical conductivity, natural corrosion resistance, and excellent ductility. In soft annealed coil form, seamless drawn tubing is heat-treated to a soft temper so it bends without cracking and springs back very little. It remains a seamless, hollow tube with a smooth bore and a clean exterior for flaring, compression fittings, and brazing. US buyers search this product as “soft copper tubing,” “annealed copper coil,” “soft copper coil,” “copper coil tubing,” “flexible copper tubing,” and “copper refrigeration coil.” Rigid, non-annealed tubing is supplied separately as straight copper tube.

Outer Diameters and Coil Lengths

Soft copper tubing is selected by outer diameter (OD), with the standard wall. The available small OD range is shown below with approximate inch equivalents; choose the OD variant, then specify the length by meter/foot or choose a roll. Live variants reflect the ODs actually stocked.

Soft coil is supplied by the meter/foot or in continuous rolls. Rigid straight copper tube is available for manifolds, heat exchangers, and fixed equipment in the copper tube collection; a different wall thickness or non-standard OD can be noted as a custom requirement.

Key Properties of Soft Annealed Copper Coil

1
99.9% Pure CopperHigh-purity copper 110 for efficient heat transfer and dependable corrosion resistance.
2
Soft Annealed TemperAnnealed to bend easily and hold shape without cracking or strong springback.
3
Seamless BoreSeamless drawn tube with a smooth inner bore and clean surface for flaring and brazing.
4
Continuous LengthsCoil form gives long runs with fewer joints and fewer leak points.

Why Choose Soft Copper Tubing Instead of Straight

  • Bends on site — annealed copper coil follows walls, bulkheads, and equipment frames without prefabricated elbows.
  • Fewer joints — one continuous coil replaces multiple straight sections and fittings, reducing labor and leak points.
  • Fast HVAC and appliance work — the standard material for refrigerant line sets, air-conditioner connections, and heat pumps.
  • Easy to store and transport — coils are compact to ship and handle, and buyers unroll only the length needed.
  • Familiar to installers — flares, compression fittings, and brazed joints are all made with standard field tools.
  • Buy by the meter or roll — take the exact length for a repair, retrofit, or full installation.

How to Order Soft Copper Coil

1. Select outer diameter

Choose the OD in millimeters or its approximate inch equivalent to match the existing line, flare, or compression fitting. Tubing is selected by actual outer diameter.

2. Choose length by meter or roll

Order cut coil by the meter/foot for repairs and short runs, or continuous roll lengths for full installations. Each coil is one seamless length.

3. Plan fittings and bending

Use a tubing bender for tight bends and a flaring tool for joints. If a different wall thickness or non-standard OD is needed, specify it as a custom requirement.

Industries That Use Soft Copper Coil

  • HVAC & refrigeration — field-installed refrigerant line sets, split-system air conditioners, heat pumps, and chillers.
  • Plumbing & gas fitting — flexible water and gas supply runs, especially where the route bends around framing and equipment.
  • Appliance & vending manufacturing — built-in cooling, heating, and fluid connections inside compact machines.
  • Automotive, marine & RV — routed fuel, oil, coolant, and refrigeration lines in confined spaces.
  • Maintenance & retrofit — repairs and replacement runs that need continuous lengths with minimum fittings.
  • Laboratory & small equipment — flexible cooling and fluid connections for apparatus and process equipment.

Working & Installation Notes

Soft annealed copper coil bends by hand for gentle curves or with a tubing bender for controlled tight bends; using a bender or spring keeps the bore round and prevents kinks that would restrict flow. The tube is cut square with a tubing cutter and deburred before flaring, and joints are made with standard flare or compression fittings, or by brazing and soldering. Long unbroken runs reduce the number of connections, and the soft temper lets the tube lie neatly against walls and cabinets. Coil should be unrolled without sharp folds, and open ends should be kept capped or clean until installation to protect the seamless bore.

Soft Coil vs Straight Tube

  • Soft annealed coil (this product) is flexible and bendable for field routing, HVAC line sets, gas and water runs, and long continuous lengths.
  • Straight tube is rigid hard-drawn tubing for manifolds, heat exchangers, fixed equipment, and machined assemblies that need to hold position.
  • Both are seamless 99.9% pure copper 110; the difference is the annealed soft temper versus the hard straight temper.

Custom Lengths and Custom Walls

Soft annealed copper coil is supplied cut to the length you need, by the meter/foot or in continuous roll lengths, in millimeters or inch-equivalent ODs. A non-standard outer diameter or a different wall thickness is handled as a custom order, with handling time extended according to the difficulty and complexity of the work. All standard coil lengths use the same seamless pure copper 110 material as the straight tube range.

Shipping & Delivery

Standard (in-stock) soft annealed copper tubing coil ships within 1–5 business days.

Custom-cut or processed orders require additional handling time based on processing difficulty and complexity.

After shipment, delivery typically takes 7–15 days to arrive, depending on the destination.

Soft Annealed Copper Coil FAQ

What is soft annealed copper tubing?

It is seamless pure copper 110 tube that has been annealed to a soft temper so it bends easily without cracking and is wound into a coil for long continuous runs in HVAC, gas, and water installations.

How is soft copper coil sold and measured?

By outer diameter (OD) with the standard wall, and by length — either cut by the meter/foot or in continuous roll lengths. OD is shown in millimeters and approximate inch equivalents.

Can I bend soft copper tubing by hand?

Yes for gentle curves; for tight bends use a tubing bender or bending spring to keep the bore round and avoid kinking. The annealed temper holds the bent shape with little springback.

What joints does copper coil use?

Standard flare and compression fittings, brazing, and soldering. The tube is cut square and deburred before flaring so fittings seat and seal correctly.

Should I use soft coil or straight tube?

Use soft coil for field routing, line sets, and runs with many bends; use rigid straight tube for manifolds, heat exchangers, and fixed equipment where the line must hold position.

Can I order a different wall thickness or a specific roll length?

Standard coils use the standard wall; different walls, non-standard ODs, or specified roll lengths are handled as custom orders with additional handling time based on the processing required.
