Product Details

The MAHLE B33276 is a precision-engineered O-ring designed to seal the engine coolant thermostat housing, preventing coolant leaks and maintaining proper cooling system pressure. This essential sealing component creates a reliable barrier between the thermostat housing and engine block or intake manifold mounting surface.

Key Features:

  • OEM-quality seal manufactured to exact specifications for proper fit and function
  • High-temperature resistant elastomer construction withstands engine coolant temperatures
  • Chemical-resistant material compatible with modern coolant formulations including extended-life coolants
  • Precision-molded design ensures consistent sealing surface and proper compression
  • Direct replacement for worn or damaged original O-ring

MAHLE gaskets and sealing products are trusted by Original Equipment Manufacturers and professional technicians worldwide, delivering reliable sealing performance backed by decades of engineering expertise. Replace this O-ring whenever servicing the thermostat or thermostat housing to prevent coolant leaks and ensure optimal cooling system operation.
