To specify a 214 beer can bottom end that fits your can body, confirm more than the size code. Match the end’s complete profile and seaming dimensions to the body flange, the seaming equipment, and the approved technical drawing. In common fractional-inch notation, “214” is often read as 2-14/16 inches, or 2.875 inches (about 73.0 mm) in nominal diameter; treat that as a starting reference, not a complete fit specification. Before ordering production quantities, ask your supplier and can-body producer to confirm the same drawing revision and validate the combination on the intended seaming line.
A can end and body form a double seam, so their mating features must work together during seaming. An end that appears to be the correct nominal size may still be unsuitable if its curl, countersink, chuck wall, or other profile features differ from the body and tooling requirements. Compatibility also depends on the body flange and the seamer setup used on your production line. For that reason, treat the size code as one part of the specification rather than a guarantee of interchangeability.
Different manufacturers may use drawings or reference points that are not directly comparable from a short code alone. Confirm which dimensions are controlled, how they are measured, and which drawing revision governs the order. Where possible, have the end supplier and body supplier review the same document set. This simple coordination can help identify a mismatch before it reaches a production trial.
Start by asking the supplier to confirm what “214” means for the specific product being quoted. If the designation follows common fractional-inch notation, 2-14/16 inches equals 2.875 inches, approximately 73.0 mm. Do not assume this nominal figure defines the finished end’s full geometry or the exact measurement location. Request a dimensioned drawing that identifies the relevant diameters, profile features, and measurement datums.
Obtain the can-body drawing or specification from your body supplier, including the flange details required for seaming. Compare the end’s curl and profile with the body flange and the seaming system’s requirements. Ask both suppliers to identify any dimensions that must be matched or verified together. If one party cannot confirm compatibility from the drawings, arrange a sample evaluation rather than relying on the size code.
Tell the end supplier what seaming equipment and tooling will be used, including any relevant chuck or roll details available from your production team. Tooling condition and setup can affect seam formation, so a specification that worked on another line should not be treated as automatic approval for your line. Agree on the trial method and acceptance criteria with your quality and production teams before testing. Keep the approved tooling and process conditions with the trial record.
State the intended beverage, filling process, and any relevant storage or distribution conditions. Ask the supplier to confirm the proposed end material, temper, thickness, coating, and internal protection options against your application requirements. These details should be documented rather than inferred from the 214 designation. Any food-contact, regulatory, or performance requirements should be provided by your company and confirmed with the supplier for the target market.
Request representative samples and inspect them against the agreed drawing. As a practical dimensional check, measure the selected feature at three evenly spaced positions around the circumference where the drawing permits; this can help reveal variation that a single reading may miss. Record the measuring method, instrument, sample identification, and drawing revision so the results are traceable. Final acceptance limits should come from the approved specification, not from an assumed industry-wide tolerance.
Then run a controlled seaming trial using the intended body, end, tooling, and operating setup. Have qualified personnel evaluate the seam using your established inspection procedure and acceptance criteria. A visual check alone should not replace any dimensional or destructive examinations required by your quality system. Approve the combination only after the responsible teams have reviewed and documented the results.

Identify the dimensions that control fit and seam formation on the relevant drawings. These may include the nominal diameter, end profile, curl, countersink, and body-flange geometry, but the controlled features depend on the product design. Ask the supplier to mark the critical dimensions and state the tolerances available for the quoted item. Avoid comparing measurements taken from different datums or using a drawing that has been superseded.
Agree on approval criteria before samples arrive. Your team may need to review dimensional conformity, seamer performance, seam inspection results, coating suitability, and documentation. The criteria should reflect your equipment, product, and internal quality procedures. If a change is made to the end, body, coating, tooling, or process, decide whether that change requires renewed evaluation.
Record the supplier’s product code, drawing number and revision, material and coating details, packaging requirements, and approved sample status in the purchase specification. Clarify how the supplier will notify you of proposed changes that could affect fit or performance. Make sure purchasing, engineering, production, and quality teams use the same approved version. This reduces the risk of an order being placed against an outdated or incomplete description.
Send a complete inquiry package rather than a short request for “214 ends.” Include the can-body drawing, end drawing if available, seamer and tooling information, target quantity, intended application, and required documents. Clearly distinguish confirmed requirements from details that still need supplier review. This gives the supplier a better basis for checking fit and identifying missing information.
When comparing offers, evaluate drawing alignment, sample availability, change-control practices, packaging, delivery terms, and technical communication alongside price. Ask what information is needed to confirm production feasibility and whether the supplier can support sample review and specification clarification. Avoid treating an unconfirmed lead time or compatibility statement as a guarantee. Put agreed technical and commercial conditions in writing before order release.
At Wanhua, we can review your 214 beer can bottom end inquiry alongside the available body and application information. Share your drawings, target market requirements, estimated order quantity, and seaming details so our team can clarify which specifications need confirmation before quotation or sampling. Where information is incomplete, we can help identify the questions that should be resolved with your body supplier or production team. Any product fit or performance decision should be based on the agreed documentation and evaluation for your line.
For a useful first review, prepare the current body specification, the required end profile or drawing, the planned use, and your sample or trial expectations. We can then discuss the appropriate next steps for specification alignment, sample evaluation, and commercial inquiry. This process helps keep the purchase decision tied to a documented compatibility check rather than the size code alone.
To specify 214 beer can bottom ends for can-body compatibility, confirm the exact size interpretation, compare the controlled end and body drawings, and account for the seamer and tooling used in production. Then document material and coating requirements, define acceptance criteria, and validate representative samples through your established trial process. The 214 designation is a useful starting point, but it is not a substitute for a complete specification or line-based approval. Send Wanhua your drawings and application details to begin a focused technical and sourcing review.
