What Are Chicken Feet Copper Fittings?
Chicken feet copper fittings are compact copper tube components with a curved route and a branch connection. The name describes their claw-like shape, as shown in the product photographs. They are used where the tube path and branch outlet must fit an air conditioning or refrigeration assembly.
Unlike a simple two-ended return bend, this configuration combines a bend with a tube junction. The component drawing defines the connection arrangement, leg lengths, branch location and space required for installation. Each port should be identified so the mating dimensions and joining requirements are clear.
For the wider product family, see our copper tee fittings for refrigeration and copper branch fittings.

Chicken Feet Copper Fitting Configurations
The following features can be specified for review. Each proposed configuration is checked against the material, forming requirements and mating assembly before supply is confirmed.
Curved Route & Leg Spacing
Define the bend radius, distance between tube centerlines and overall envelope. These dimensions locate the curved section within the equipment and establish clearance to adjacent components.
Branch Position & Orientation
Locate the branch from a clear datum and show its direction in the assembly. Mark all ports and include the branch projection so mating tubes can be checked without relying on a single photograph.
Connection-End Features
Specify the actual mating diameters and straight lengths available for joining. Expanded or other formed end profiles are subject to review with the selected tube dimensions and joining process.
Custom OEM Arrangements
Non-standard leg lengths, unequal port sizes or installation constraints can be submitted with a controlled drawing. The quotation and approved sample define the final supplied geometry and manufacturing scope.
Copper Fitting Manufacturing & Processing
Yijin provides drawing-based copper component manufacturing. We review the curved route, junction geometry and connection interfaces together before confirming the process and tooling.
Tube Forming & Cutting
The copper grade, tube dimensions and drawing geometry guide the forming and cutting plan. Bend quality, branch location and leg alignment are reviewed against the agreed component specification.
Branch & Connection Preparation
The branch and mating ends are prepared to the approved drawing. Connection diameter, straight joining length, end orientation and any additional assembly operations are confirmed before sample approval.
Cleaning, Handling & Packing
Parts are reviewed for burrs, visible forming defects and surface damage. Agree internal-cleanliness requirements and protective packing so the curved legs, branch and connection ends are supported during handling.
Applications of Chicken Feet Copper Fittings
These curved copper branch components are reviewed for compact tube junctions in compatible equipment. Application images illustrate equipment categories and are not records of supplied Yijin projects.
Air Conditioning Systems
For air conditioning tube layouts requiring a curved route and branch connection in limited space. Define port orientation and clearance from the cabinet, nearby components and joining tools on the assembly drawing.
Refrigeration Equipment
For drawing-specific junctions in compatible refrigeration tube assemblies. The equipment designer specifies the fluid, operating conditions and joining requirements; Yijin reviews the component geometry and manufacturing scope.
Heat Exchangers
For branch connections near heat exchanger tube circuits where bends and outlet positions must fit the assembly. The curved shape alone does not establish a calibrated refrigerant distribution or equal flow split.
Custom Chicken Feet Copper Fittings for OEM Projects
Send the component drawing together with the mating tube layout. This allows Yijin to review the features that control installation, joining and repeat production for your project.
Geometry & Assembly Clearance
State tube OD, wall thickness, bend radius, leg spacing and branch position. Include the installation envelope and keep-out areas around the connection ends so the sample can be checked in its intended assembly.
Copper Grade & Delivery Condition
Identify the governing standard, material designation, tube condition and document requirements. TP2 or C12200 specifications can be submitted for review; material acceptance follows the agreed order specification.
Port Fit & Joining Requirements
Label the ports and specify each connection diameter, insertion length and end profile. Include the joining process and any fixture or mating-fit requirements that affect approval of the component.
Samples & Repeat Production
Separate initial sample demand from recurring batch quantity. Agree the drawing revision, critical checks, accepted sample and packaging before repeat orders, and communicate any changes to mating parts.
Quality Control & Inspection
Inspection requirements are tied to the approved drawing and the agreed sample or acceptance criteria. Particular attention is given to the curved route, projecting branch and connection ends that determine assembly fit.
| Inspection Area | What We Review |
|---|---|
| Tube & Connection Dimensions | Specified tube dimensions, port diameters, end profiles and straight joining lengths. |
| Bend & Branch Geometry | Bend radius, leg spacing, branch position, outlet direction and overall installation envelope. |
| Surface & Internal Condition | Visible cracks, excessive deformation, burrs, surface damage and agreed cleanliness requirements. |
| Assembly Fit & Additional Testing | Mating-fit checks and any required leak or pressure tests, including method, conditions, sampling and acceptance limits, as agreed. |
Required material documents and test records should be stated in the inquiry. Application approval and operating limits must be established for the finished assembly.

Chicken Feet Copper Fittings FAQs
What are chicken feet copper fittings?
Chicken feet copper fittings are shaped copper tube components named for their curved, branching appearance. This product family combines a bent tube route with a branch connection for an HVAC or refrigeration assembly. The name is a shape description; the controlled drawing defines the actual ports, dimensions and supplied configuration.
Are these fittings the same as copper U-bends?
A simple copper U-bend has two open ends and provides a return route. The chicken feet configuration shown here includes a branch connection as well as curved legs. Choose the part by its port arrangement, connection dimensions and circuit layout, rather than by appearance or a general U-bend name.
Can the tube size and branch position be customized?
Yes. Yijin reviews drawing-based requests for tube diameter, wall thickness, bend radius, leg spacing and branch position. Include the overall envelope and straight lengths needed for joining. Manufacturing feasibility, tooling, tolerances and sample requirements are confirmed after the complete geometry and copper specification have been reviewed.
Which copper grade should I specify?
Specify the copper designation, governing material standard, delivery condition and required documents on your drawing or purchase specification. The appropriate material depends on the intended circuit and forming requirements. TP2 or C12200 requirements can be submitted for review; designations from different standards should not be assumed to be interchangeable.
Can these fittings be used with any refrigerant or pressure?
Suitability must be checked for the specific system. A product photograph does not establish a refrigerant approval, working pressure or temperature rating. Provide the design conditions, joining method and applicable requirements so the component scope and any testing can be agreed with the responsible equipment engineering team.
What information is needed for a quotation?
Send a dimensioned drawing with its revision, material specification, port identifiers, connection details and critical tolerances. Include sample and batch quantities, cleanliness requirements, required inspections, packaging and target delivery. If you only have a sample, identify the mating tubes and installation constraints so the component can be reviewed accurately.
