Premium Reinforced COMBI Seal Upgrade for Standard Single-Lip Oil Seal Applications

Problem: A standard single-lip oil seal may retain lubricant but lacks enough protection from heavy external dust and debris.

Solution: The reinforced COMBI upgrade adds a dedicated dust barrier while retaining a separate oil-sealing lip.

Key Benefits

• More external protection than a basic single lip

• Maintains oil retention

• Reduces repeat dust-related failures
