Dimensions to check
- Outside and inside diameters where applicable.
- Overall length and shoulder dimensions.
- Mounting or retaining features.
- Seal and groove geometry.
- Thread, port or connection details where applicable.
Replacement versus OEM production
For replacement parts, matching the original part number and drawing is the safest approach. For OEM production, the full technical definition should include material, tolerances, surface requirements and any required inspection criteria.
