Scope and common interpretation errors
For gasket designs with locating holes, tabs and thin connecting bridges.
Root transitions, thickness and hole-edge distances affect local stress. Misaligned housing pins can keep tabs stretched and displace the main sealing band.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Define functional zones | Mark sealing bands, locating tabs and permitted load-bearing regions separately. |
| 2 · Check tolerance combinations | Review pin-hole clearance, position tolerances and root transitions; avoid pulling parts forcibly into position. |
| 3 · Validate actual motions | Observe root deformation during real assembly actions. Keep disassembled test specimens out of delivery batches. |
A comparison to avoid misinterpretation
If an operator must stretch a tab to fit slightly misaligned pins, check the pin-hole relationship before requesting harder tab material.
Frequently asked question
Can a gasket with a torn tab be shipped if the frame is intact?
Judge it against agreed functional and appearance criteria; do not assume release on site.
