2. Material Options

We offer multiple materials to meet different application needs:

We can customize material hardness (60–90 ShA), color, and compound formulation according to your application requirements.

3. Design & Manufacturing Capabilities

Available Designs:

• Single lip and double lip oil seal rings

• Seals with or without garter spring

• Rubber-bonded or metal-cased structure

• High-speed rotary shaft seals

• Custom cross-sections and dimensions
