214 Tinplate Beer Can Top Ends: Specifications and Compatibility Guide
A 214 tinplate beer can top end is a metal closure intended to be seamed onto a compatible can body, but the “214” designation alone does not confirm that it will fit a particular can or seaming line. Under a commonly used can-end sizing convention, 214 represents a nominal diameter of 2 14/16 inches, or approximately 2.875 inches (73.0 mm). Buyers should treat that as a reference for initial identification, then confirm the supplier’s dimensional drawing, can-body match, opening design, and seamer requirements before ordering.
This guide helps packaging buyers, can makers, and beverage project teams assess the specifications that matter and prepare a clear compatibility inquiry. Since end-size terminology and product dimensions can vary by supplier or application, use documented specifications—not the size code alone—to approve a component.
Key Takeaways
- The 214 code is a useful starting point, not a complete compatibility specification.
- Confirm the end’s key dimensions and the can body’s matching flange and seam requirements.
- Review tinplate construction, coating, score and tab design, and application requirements together.
- Before production, request a current drawing and agree on sample evaluation and quality criteria with the supplier.
Who This Guide Is For
This guide is for B2B buyers evaluating 214 tinplate beer can ends for a new package, a component change, or a second-source project. It is also useful for engineering and procurement teams that need to communicate requirements to a can-end supplier. If you are replacing an existing end, have a sample or approved drawing available so the supplier can compare the actual interface rather than relying on a name alone.
What Does “214” Mean?
In a commonly used inch-based naming convention, the digits identify a nominal end diameter in sixteenths of an inch: “2” indicates two inches and “14” indicates fourteen sixteenths. This gives a nominal diameter of 2 14/16 inches, equivalent to 2.875 inches or about 73.0 mm. The conversion uses 25.4 mm per inch.
These values describe the convention, not a guaranteed finished-part measurement. Actual end geometry includes features such as the curl, countersink, and panel, and the supplier’s drawing should define the relevant dimensions and tolerances. Confirm how the supplier uses “214,” and ask which measurement the quoted size refers to, before treating it as a fit specification.
Specifications to Review
Dimensions and Seaming Interface
Compatibility depends on the relationship between the end and the can body, particularly at the flange and double seam. Request a drawing that identifies the end profile and its controlled dimensions, then compare it with the can-body specification and the seamer setup. A matching nominal size does not, by itself, demonstrate that the two components will form an acceptable seam.
Ask which dimensions the supplier controls and how changes are managed. If your line is already running another end, provide the approved end drawing and, where possible, a physical reference sample. Your can maker or seaming-equipment specialist should confirm whether any tooling, setup, or inspection adjustments are needed.
Tinplate, Coating, and Product Contact
“Tinplate” describes a steel substrate with a tin coating, but it does not specify the full material construction or protective lacquer system. Ask the supplier to identify the material and coating options offered for the intended application, and to provide the relevant product documentation for review. Do not assume that a coating is suitable for a specific beverage, process, or market without confirming its intended use.
Beer formulations, filling conditions, storage, and distribution can affect packaging requirements. Share the beverage type and the process conditions that your packaging team considers relevant, and ask the supplier to confirm which available specification is appropriate for evaluation. Any food-contact or regulatory documentation should be checked against the destination market and the specific product being purchased.
Opening Design: Score, Tab, and Panel
The score pattern and tab configuration determine how the consumer opens the can, while the panel and countersink contribute to the end’s overall design. Confirm the opening style, tab type, and any appearance or branding requirements before selecting a version. Where the end will be used on a production line, the opening features should be evaluated together with the seaming interface and handling requirements.

Matching a 214 End to Your Application
Start with the can body, not with the end code. Verify the body’s intended end size, flange geometry, and approved seam specifications with the can manufacturer or packaging engineer. Then compare those requirements with the supplier’s drawing for the proposed 214 end.
Next, consider the beverage and production process. The end specification should fit the product’s packaging requirements, filling and closing conditions, distribution expectations, and applicable market requirements. If any of these are still under development, make them explicit in the inquiry so the supplier can identify assumptions rather than quote against an incomplete brief.
A Practical Selection Framework
1. Define the Project Requirements
Prepare the target can-body specification, intended end size, opening style, coating needs, and destination market. Include the existing line or seamer information when available, and state whether you are developing a new package or replacing a current component. This context makes it easier to identify the information that still needs confirmation.
2. Request Technical Documents
Ask for a current product drawing, a written specification, and details of available material and coating options. Check that the documents identify the revision and apply to the product being quoted. If an important dimension or performance requirement is not listed, request clarification rather than assuming it is standard.
3. Confirm Compatibility Before Production
Have the can-body supplier, packaging engineer, or seaming-equipment specialist review the proposed end against the body and line requirements. Agree on how samples will be evaluated and which acceptance criteria will apply before moving toward production. A sample review can help identify mismatches, but it does not replace the agreed specification or the buyer’s own qualification process.
4. Align Commercial Terms with Technical Approval
Request a quotation that clearly identifies the product version, packaging arrangement, minimum order quantity, lead-time estimate, and any tooling or customization assumptions. These commercial details can depend on the supplier’s production plan and order scope, so obtain them in writing for the specific inquiry. Avoid comparing quotes until the technical basis and quoted scope are aligned.
Common Compatibility Mistakes
- Relying only on “214”: Ask for the full drawing and clarify the supplier’s sizing convention.
- Checking diameter but ignoring the seam: Compare the end and body interface with the approved seaming requirements.
- Assuming all tinplate ends have the same coating: Confirm the proposed material and coating for the intended application.
- Leaving opening details until later: Specify the score, tab, and panel requirements early in product evaluation.
- Approving samples without written criteria: Agree on the review method and acceptance requirements before testing.
Supplier Evaluation Checklist
A capable supplier should be able to discuss the product specification clearly and identify what information is needed to verify compatibility. Ask whether the supplier can provide a drawing, explain available material and coating choices, clarify the quoted product version, and support sample evaluation. Also establish how specification revisions, order quantities, and delivery estimates will be communicated.
At Wanhua, we can discuss 214 tinplate beer can top-end requirements with B2B buyers and review the information needed for a quotation. To support an initial assessment, share the can-body drawing or specification, end requirements, opening preference, application details, target market, and estimated order quantity. We can then clarify which product information and compatibility points need confirmation before a commercial decision.
Conclusion: How to Choose a Compatible 214 Tinplate End
A 214 tinplate beer can top end may be a suitable option when its documented dimensions, material and coating, opening design, and seam interface match the can body and production requirements. The nominal 214 size is only a starting reference; it cannot establish compatibility on its own. The practical next step is to request the current drawing and specification, have the relevant packaging or seaming team review them, and agree on sample and commercial terms with the supplier.
