Engineering considerations
- Compression set and sealing force retention over service life
- Media compatibility (fuels, oils, coolants, steam, aggressive chemicals)
- Gland fill, squeeze, and groove design guidance
- Surface finish and tolerance control for reliable sealing
Common materials
- NBR (Nitrile)
- FKM (Fluoroelastomer)
- EPDM
- Silicone (HCR)
