nylon flanged bushing
Use this page to set sample, approval and acceptance language for a nylon flanged bushing. It is not a circular-economy pledge, a carbon roadmap or an ESG scorecard.
Check the flange diameter and thickness, the ID, the barrel OD and the barrel length on the sample before it is approved. Agree the grade, color and applicable ASTM standard as an acceptance condition. Record those values so a later batch can be compared with the approved item.
What to check on the nylon flanged bushing sample
- Flange OD and thickness — measure with the unit the request used. A flange that is only “about right” is not an approval.
- Barrel ID and OD — both numbers together. A worn sample ID is not a production tolerance.
- Barrel length under the flange — the shoulder-to-end length the housing will see.
- Grade and color — natural, black or a stated color code. Do not approve “nylon” without the grade family.
- ASTM or equivalent method — only if the receiving plant will file that method on later lots.
- Packing of the sample — so later cartons can be compared with how the approved piece arrived.
Acceptance conditions that have to be written down
| Grade, color and method | |
|---|---|
| Grade family | PA6, PA66 or a named filled ask the factory will actually ship |
| Color | Natural, black or a stated color; not “close enough ivory” |
| ASTM point | The method and condition the plant will file, if any |
| Geometry the later lot must match | |
|---|---|
| Flange | OD and thickness with unit |
| Barrel | ID, OD and length under the flange |
| Fit note | Press, sliding or clearance — as measured on the approved piece |
If the factory proposes a different compound, a different density or a different flange thickness, treat that as a new request. Re-issue the line with the changed axes visible. Keep the original approved item on file. Nylon Bushing Sourcing does not store a private gold sample or convert a change into a courtesy upgrade.
Virgin versus reprocessed nylon on the approved piece
One view accepts a reprocessed or leftover bar when the flange is a maintenance spare and the plant will not file food-contact or flame files. The opposing view insists on virgin or a named melt when inspectors will later ask for FDA 21 CFR 177 on the lot, or when density in g/cc is how incoming QC rejects a lighter regrind. Write which view the sample represents. An approved nylon flanged bushing that never recorded that split cannot police the next carton.
Evidence that travels with an approved nylon flanged bushing
- Dimensional page of the sampleID, OD, flange and length as accepted, with units.
- Grade and color statementThe wording that will appear on the invoice for later lots.
- Named ASTM methodOnly when the buyer made that method an acceptance condition.
- Factory lot markSo a later carton can be traced to the same process, not to this desk.
Hold the sample gate before the production lot
Tell the desk that approval is required. Share flange, barrel, grade, color, quantity and destination. Eligibility for FREE sourcing support and any figure up to 3% is confirmed after that review.
