Premium Reinforced-Shell COMBI Seal for Harsh Dusty Working Conditions

Problem: Thin seal cases can distort during installation or severe service, opening contamination paths and reducing lip contact.

Solution: The reinforced outer shell preserves roundness, press fit and sealing alignment in harsh dusty environments.

Key Benefits

• Resists case distortion

• Maintains stable lip alignment

• Helps prevent dust bypass
