The purchasing decision
Use the original assembly reference and define the required element specification. Ask for service documentation and compatible replacement seals. Record cleaning or replacement criteria rather than assuming every element is reusable.
Keep these records
- Element and housing match.
- Seal/material identity.
- Approved service instruction.
Give each record an owner and a revision or date. If a supplier proposes a different part or test condition, record it as an exception for review before treating the quotation as equivalent.
Turn the review into a sourcing request
Start with the linked component checklist, add the actual platform and part identity, and state quantity, destination and timing. List unresolved requirements explicitly so the first discussion can focus on those gaps.
