Material Selection Guide
Material selection should reflect the actual service conditions, not just the part size. Media compatibility, operating temperature, movement, outdoor exposure, pressure, and compliance needs all influence which elastomer family becomes the right starting point.
Typical decision factorsMedia, temperature, pressure, movement, environment, and approval requirements.
Common material familiesNBR, FKM, EPDM, Silicone, HNBR, PTFE, FFKM, PU and related specialty options.
Good starting questionWhat fluid will the seal touch, and what temperature range will it actually see?
When to ask for helpWhen service conditions combine chemicals, heat, motion, weathering, or compliance requirements.
Usually selected for
- Oil and fuel service
- Water, steam, and weather exposure
- High temperature process service
- Low-friction or aggressive chemical applications
Check carefully when
- Multiple media are present in one system
- Short-term peak temperatures differ from normal conditions
- Dynamic duty increases wear or extrusion risk
- Compliance or traceability requirements apply
