⚠ VERIFY BEFORE ORDERING
Wrong material = failure. Viton for oil/fuel, EPDM for water/steam, Buna-N for general purpose, Silicone for food-grade.
Chemical incompatibility causes swelling, brittleness, or rapid degradation
✓ BROKER TIP
Durometer (hardness) affects sealing pressure tolerance. Higher Shore A = harder = higher pressure.
Standard durometer is 70A — verify if application requires different hardness
