Grade: SAE J200, ISO 6194, or OEM-specific standards

Viscosity: Compatible with SAE 15W-40 to SAE 40 marine engine oils

Buoyancy: Non-buoyant, designed for submerged or high-pressure environments

Material: Nitrile rubber (NBR), Fluorocarbon (FKM/Viton), or Polyacrylate (ACM)

Temperature Range: -30°C to +150°C (varies by material)

Pressure Resistance: Up to 10 bar (depending on design)

Chemical Resistance: Resistant to oil, fuel, and seawater

Hardness (Shore A): 70-90 (typical for marine applications)

Seal Type: Lip seal, radial shaft seal, or mechanical seal
