Scope and common interpretation errors
For maintenance specifications on repairable equipment. Existing mandatory replacement rules remain applicable.
Compression, heat and chemical exposure can leave invisible changes; removal can add stretch or tool damage. New-part dimensions may not establish an old seal's remaining life.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Check product rules | Confirm replacement requirements and whether service history is traceable. |
| 2 · Inspect and classify used seals | Record deformation, cracks, cuts, contamination and elastic condition with photographs and service details. |
| 3 · Validate the repair | Reuse requires an approved basis and assembly testing. One leak-free test is not a future-life guarantee. |
A comparison to avoid misinterpretation
A never-used ring and a similar-looking ring removed after long compression must not share one accepted-material bin. Separate and label their origins.
Frequently asked question
Can boiling a used seal restore it for reuse?
An unvalidated recovery treatment can alter its condition and is not a default maintenance method.
