A 214 beer can bottom end is a metal end identified by a nominal size designation, but “214” alone does not confirm that it will fit a particular can body or seaming line. In fractional-inch sizing conventions, 214 is commonly read as 2 14/16 inches, or 2.875 inches (approximately 73.0 mm); treat this as a nominal reference, not a guaranteed finished-end or seam dimension. To assess compatibility, compare the supplier’s technical drawing with your can-body profile, seamer tooling, end material, and required performance. At Wanhua, we recommend confirming those details before requesting a production quotation or approving an order.
This guide is intended for breweries, beverage-can manufacturers, packaging procurement teams, and importers evaluating 214 beer can bottom ends. It is most useful when you are sourcing a replacement end, comparing supplier drawings, or checking whether a proposed specification matches existing equipment. It can also help teams prepare a clearer request for quotation. The final compatibility decision should be based on your actual can and equipment specifications.
A can end closes one end of a metal beverage container and joins the can body through a double seam. The bottom end contributes to package closure and structural performance, while its geometry must work with the body flange and the seaming system. “Bottom end” describes its intended position in the package; it does not by itself define the end profile, metal gauge, coating, or opening features. Confirm the intended application with the supplier rather than relying on the size label alone.
The number helps identify a nominal size class under the supplier’s sizing convention. It does not establish every critical dimension, including the finished outside diameter, curl geometry, countersink depth, or the formed seam dimensions. Different drawings or equipment configurations may require specific values even when the ends share a 214 label. Ask the supplier to state the convention used and provide a controlled drawing with the dimensions relevant to your line.
A useful specification review covers the complete end and its interface with the can body. Compare the following items against your current approved component drawing and seamer requirements. If a value is missing or unclear, request written confirmation instead of assuming that a familiar designation means an identical part. Keep the final, approved specification attached to the purchase documentation.
| Specification area | What to confirm | Why it matters |
|---|---|---|
| Size and geometry | Supplier’s 214 sizing convention, end diameter, curl, countersink, and profile dimensions | Dimensions affect fit with the body flange, tooling, and formed seam. |
| Material | Metal type, alloy or temper where specified, and stock thickness or gauge | Material properties and thickness influence forming and package performance. |
| Coating and compound | Interior and exterior coating requirements, sealing compound details, and intended product contact | These details need to suit the package design, beverage, and handling conditions. |
| Seaming compatibility | Chuck and roll compatibility, body flange requirements, and the line’s operating setup | A nominally matching end may still require tooling or process verification. |
| Quality documentation | Inspection criteria, batch identification, packaging, and required documents | Clear requirements help buyers and suppliers evaluate deliveries consistently. |
End compatibility is a system check, not a simple diameter comparison. A double seam is formed in two operations, and the resulting seam depends on the end, body flange, tooling, and seamer setup working together. A mismatch may cause poor seam formation, leakage risk, equipment disruption, or rejected production, so a size label should never be treated as proof of line readiness. Your can maker or seaming-equipment specialist can help verify the required interface dimensions and process limits.
You will get efficient and thoughtful service from Wanhua.
Compare the proposed end drawing with the can body’s neck, flange, and mating dimensions. Confirm that the end profile is specified for the intended body design, and check whether the can has undergone any changes since the current end was approved. If the body and end come from different suppliers, share the relevant drawings with both parties so they can review the interface. Do not rely on visual similarity as a substitute for dimensional confirmation.
Ask your equipment team to verify that the end is suitable for the installed chuck and seaming rolls. Confirm any setup requirements, inspection method, and acceptance criteria before scheduling a trial. During evaluation, inspect the seam using the method and limits approved for your line and package specification. Record the end batch, machine settings, and inspection results so that the decision can be traced and repeated.
The price of a 214 end depends on the confirmed specification, order volume, material and coating requirements, packaging, and delivery arrangement. Minimum order quantities and lead times are supplier- and order-specific; they should not be inferred from the nominal size. For a useful comparison, ask each supplier to quote against the same drawing revision and commercial terms. Clarify whether samples, tooling considerations, freight, and documentation are included or quoted separately.
Choose a supplier that can provide a clear, reviewable specification and respond to compatibility questions. Ask how product dimensions and agreed quality requirements are documented, how batches are identified, and how changes to the specification are communicated. Confirm export packaging and shipping arrangements if the order crosses borders. These checks support a more controlled sourcing decision without assuming that any supplier can meet requirements that have not been discussed.
Wanhua supplies packaging products and supports B2B buyers evaluating 214 beer can bottom ends for their intended application. Share your drawings, target quantity, delivery destination, and any coating, material, or documentation requirements so we can review the request against the information provided. If you are replacing an existing end, include the approved part reference and explain whether your can body or seaming equipment has changed. We can then discuss the specification, sample evaluation, quotation, and supply details relevant to your project.
A 214 beer can bottom end may be a candidate for your package, but the designation alone cannot establish compatibility. Confirm the supplier’s sizing convention, compare the complete end and body drawings, and check the material, coating, compound, and seaming requirements with your production team. Then evaluate samples under an agreed inspection plan before approving routine supply. To begin a purchasing review with Wanhua, send the current component drawings, application details, required quantity, and destination for a specification check and quotation discussion.
