Long-term sealing behavior and compression review
Compression set work starts with the sealing interface. Compression percentage, temperature, time, media contact and gasket geometry decide whether a material route can support long-term sealing.
Product Fit
For sealing projects where recovery, compression condition, service exposure, and long-term performance targets need review.
Compression condition
The assembled height, gland depth and squeeze percentage shape the material and geometry review.
Exposure window
Temperature, time, media and cycling conditions determine whether a short sample check is enough or aging evidence is needed.
Seal geometry
Flat gasket, profile, ring and molded seal forms need different tolerance and compression planning.
Engineering Review Inputs
A compression-set RFQ should describe how the seal is compressed in the real assembly.
- Seal drawing, groove or mating surface details
- Original height, assembled height and compression percentage
- Temperature, duration, cycling and media exposure
- Material hardness, color and part form
- Target compression set method or customer validation route
- Sample quantity, inspection dimensions and production quantity
Manufacturing Route
Long-term sealing review connects geometry, material choice and inspection points before sample preparation.
Geometry route
The part may be reviewed as a gasket, profile, ring or molded seal depending on the sealing interface.
Material screening
Hardness, recovery behavior, heat exposure and media contact are checked against the assembly condition.
Inspection planning
Critical height, width, cross-section or ID/OD dimensions are selected from the actual sealing function.
DFM / Tolerance Review
- State assembled compression instead of only giving free-state thickness.
- Separate long-term sealing dimensions from non-critical outline dimensions.
- If the part cycles between compression and release, describe the cycle and dwell time.
Testing / QC Boundaries
- Compression set checks require method, temperature, time and specimen form.
- Dimensional inspection should focus on the sealing section and assembled height relationship.
- Aging or media exposure checks are handled by project scope and material batch.
RFQ Parameters
For compression set review, send the assembly condition and validation method together.
Compression set and long-term sealing support depends on geometry, material, exposure and agreed test method; no blanket service-life or certification promise is made.
- Seal drawing or sample reference
- Compression percentage
- Temperature and exposure time
- Media or environment
- Validation method and quantity stage
