Scope and common interpretation errors
For static seals on thin covers and long frames. Leak location alone does not prove a unique root cause.
Housing stiffness, screw spacing, gasket reaction and temperature influence the closed shape. Acceptable free-state flatness does not guarantee no local gap under preload or pressure.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Map leak coordinates | Overlay leak locations with screws, ribs and corners. |
| 2 · Measure the closed shape | Record edge gaps under agreed loads and tightening sequence. Keep free-state and loaded measurements distinct. |
| 3 · Compare structural changes | Use controlled samples to evaluate supports, span or seal section, changing one factor at a time. |
A comparison to avoid misinterpretation
If extra torque deepens marks near screws but the midspan leak remains, investigate load transfer rather than immediately thickening the entire gasket.
Frequently asked question
Can softer rubber compensate for every cover distortion?
No. It may reduce reaction force but also create positioning or durability issues.
