Materials
Compound selection by working condition
| Material | Common discussion points | Typical applications |
|---|---|---|
| NBR | Oil resistance, cost-effective industrial sealing | Hydraulic, pneumatic, machinery, pump and valve parts |
| FKM / Viton type | Higher temperature, oil, fuel and chemical exposure | Automotive, fuel systems, chemical equipment, demanding seals |
| EPDM | Water, steam, weathering and outdoor conditions | Water treatment, HVAC, plumbing, outdoor equipment |
| Silicone | Flexibility, color, wide temperature range and food-contact review | Food equipment, medical-style equipment discussion, electronics, appliances |
| HNBR | Improved heat, oil, wear and mechanical performance over standard NBR | Automotive, oilfield, hydraulic and demanding dynamic sealing |
| CR / Chloroprene | Weathering, ozone, moderate oil exposure and general-purpose performance | Outdoor equipment, industrial profiles and general machinery |
| PTFE (non-elastomer) | Low friction and broad chemical resistance; elastic recovery requires design review | Backup rings, seats and chemical-service sealing components |
