The best 3/4-inch copper tubing in a 50-foot coil depends on the specifications and documentation your project requires. The GOORY and BELLA BAYS coils list C12200 copper, a 0.8 mm wall, and ASTM B280 compliance; ICS Industries is another 50-foot option described for ACR use. ELECTRAPICK lists the same nominal dimensions but gives the inside diameter as 11/16 inch. Compare the product details with your system requirements before ordering.
| Product | Length and dimensions | Best suited for |
|---|---|---|
| GOORY C12200 ACR tubing | 50 ft; 3/4 in OD, 0.687 in ID | Buyers seeking listed ASTM B280 and nitrogen-treatment details |
| BELLA BAYS C12200 ACR tubing | 50 ft; 3/4 in OD, 0.687 in ID | HVAC and refrigeration buyers comparing listed coil specifications |
| ELECTRAPICK soft-coil tubing | 50 ft; 3/4 in OD, 11/16 in ID | Projects where its stated dimensions match the design |
| ICS Industries ACR tubing | 50 ft; 3/4 in OD | Buyers prioritizing a seamless ACR coil with fewer inline joints |
| BELLA BAYS 25-foot coil | 25 ft; 3/4 in OD, 0.687 in ID | Shorter runs where 50 feet is unnecessary |
GOORY 50-Foot C12200 ACR Copper Tubing
This is a strong match for buyers who need a flexible 50-foot refrigeration coil with clearly stated dimensions. GOORY specifies annealed UNS C12200 copper, a 3/4-inch outside diameter, a 0.687-inch inside diameter, and a 0.8 mm wall. The listing also states that the tubing complies with ASTM B280.
Why it was selected: The description identifies the copper grade, standard, length, and nitrogen-charged manufacturing treatment. It also notes pressure testing, corrosion resistance, and flexibility for installation. These details make it easier to compare with ACR project requirements.
Best for: HVAC and refrigeration buyers seeking listed ACR specifications and treatment details. Limitation: The stated wall is 0.8 mm, so confirm that thickness and all system requirements are appropriate for the intended application.
BELLA BAYS 50-Foot ASTM B280 Coil
BELLA BAYS specifies annealed UNS C12200 seamless copper with a 3/4-inch outside diameter, 0.687-inch inside diameter, 1/32-inch wall, and 50-foot length. The listing says the coil conforms to ASTM B280 and describes it as flexible, corrosion resistant, and suitable for HVAC, refrigeration, and other applications.
Why it was selected: It offers a detailed set of dimensions and ACR-related specifications for buyers comparing 50-foot coils. Its listed nitrogen-charged treatment and pressure testing are additional product details to consider when reviewing the listing.
Best for: Buyers who want the dimensions expressed in both fractional and metric terms and a coil described as seamless. Limitation: Confirm the 1/32-inch wall specification against the exact requirements for the planned installation.
ELECTRAPICK 50-Foot Soft Copper Coil
ELECTRAPICK lists a 50-foot seamless soft-copper coil made from C12200 copper. Its stated dimensions are 3/4-inch outside diameter, 11/16-inch inside diameter, and 0.8 mm wall thickness. The product description emphasizes heat transfer, corrosion resistance, and use in air-conditioning and refrigeration applications.
Why it was selected: The coil has the requested outside diameter and length, and the listing clearly describes its material and wall thickness. It can be compared with the other options when the stated inside diameter is suitable for the project.
Best for: Buyers whose design calls for the listed 11/16-inch inside diameter. Limitation: The listing does not state ASTM B280 compliance in the supplied features, so do not assume that standard applies; verify any required documentation.
ICS Industries Seamless ACR Tubing
ICS Industries describes this product as a 3/4-inch outside-diameter, 50-foot coil of seamless soft copper tubing for air-conditioning and refrigeration. The listing highlights clean interior surfaces, high-pressure resistance, and a flexible coil intended to support bending with fewer inline joints.
Why it was selected: Its ACR focus and continuous 50-foot coil make it relevant to buyers who want to plan a run with minimal connections. The supplied features say it is manufactured to meet stringent ASTM standards, but do not name a specific standard.
Best for: Buyers prioritizing an ACR-oriented seamless coil and reduced inline joints. Limitation: The supplied details do not specify the inside diameter, wall thickness, or exact ASTM standard. Confirm those details before choosing it for a dimension-sensitive job.
BELLA BAYS 25-Foot Copper Coil
This BELLA BAYS option has the same listed diameter and material details as its 50-foot counterpart, but comes in a 25-foot coil. The specifications include annealed UNS C12200 copper, a 3/4-inch outside diameter, a 0.687-inch inside diameter, a 1/32-inch wall, and stated ASTM B280 compliance.
Why it was selected: It gives buyers a shorter-coil alternative when the project does not require 50 feet, potentially avoiding surplus material. Best for: Shorter refrigeration or HVAC runs with matching specifications. Limitation: It does not meet a strict 50-foot quantity requirement; select a longer coil or confirm whether another quantity is needed.
Buying Guide: How to Choose 3/4-Inch Copper Tubing
Does 3/4 inch mean the inside diameter?
For these listings, 3/4 inch refers to the outside diameter. Several products specify an inside diameter of 0.687 inch, while ELECTRAPICK lists 11/16 inch. Check both measurements, along with wall thickness, against the project design rather than relying on the nominal size alone.
Should you choose ACR tubing for refrigeration?
ACR means air-conditioning and refrigeration in the product descriptions. GOORY and BELLA BAYS explicitly list ASTM B280 compliance; ICS Industries refers to ASTM standards without naming one in the supplied details. If a particular standard or documentation is required, confirm it with the seller or product documentation.
How much tubing do you need?
Measure the planned route and account for bends, connection layout, and installation needs before selecting a coil length. A 50-foot coil suits projects that need that much continuous tubing. A 25-foot option may be more practical for a shorter run, but it will not satisfy a full 50-foot requirement.
What else should you verify before ordering?
- Confirm outside diameter, inside diameter, wall thickness, coil length, and copper grade.
- Check whether the product listing identifies the required ACR standard.
- Compare the soft-coil format and stated flexibility with the planned routing and installation method.
- Follow applicable system requirements and installation guidance; do not infer pressure suitability from a general product description alone.
Frequently Asked Questions
What is the outside diameter of 3/4-inch copper tubing?
The listed products describe 3/4 inch as the outside diameter, equivalent to 19.05 mm.
Are all five options 50 feet long?
No. Four products are listed as 50-foot coils. The BELLA BAYS alternative is 25 feet long.
Which listed products specify ASTM B280?
GOORY and both BELLA BAYS listings explicitly state ASTM B280 compliance. The ICS listing mentions ASTM standards without identifying a specific one in the supplied features.
Is 0.687 inch the same as 11/16 inch?
They are close measurements: 11/16 inch equals 0.6875 inch. Compare the exact listed dimension with your project specifications.
Which option is best when inside diameter matters?
Compare the stated inside diameter directly: GOORY and BELLA BAYS list 0.687 inch, while ELECTRAPICK lists 11/16 inch. The ICS supplied details do not give an inside diameter.
