2. Crankcase Breather Gasket Function and Materials Overview

Crankcase Breather Gaskets ensure tight sealing within the crankcase ventilation or oil mist separator system. They help maintain internal pressure balance, prevent leakage of oil mist, and support proper functioning of breather filters—important for emissions control and engine cleanliness.

These Crankcase Breather Gaskets are exposed to oil, vapor, and moderate heat. They are constructed from flexible, oil-resistant materials to maintain a secure seal across metal or plastic housings.

Common material types include:

• Rubber – Offers elasticity and oil resistance for sealing molded housings
• Rubber-Coated Metal (RCM) – Provides structural integrity and reliable sealing performance under vibration or uneven mating surfaces
