Product Details

The Engineered Marine Products 32-05019 Exhaust Flapper Valve & Clamp is designed to prevent water from entering your marine engine's exhaust system through the thru-hulls when the boat is stopped or operating at slow speeds. This essential exhaust component features a durable rubber flapper valve with corrosion-resistant stainless steel hose clamps to ensure reliable performance in harsh marine environments.

Key Features:

  • Designed for 4-inch marine exhaust systems including MerCruiser and universal applications
  • Weather-resistant heavy-duty black rubber flapper valve prevents backflow
  • Adjustable stainless steel hose clamps resist corrosion
  • Includes two hose clamp-equipped exhaust caps
  • Helps protect engines from water infiltration damage

This flapper valve assembly is compatible with various MerCruiser 4-inch exhaust systems and universal marine exhaust applications. The one-way valve design allows exhaust gases to exit while preventing water from flowing back into the engine, providing critical protection when your boat is at rest or in slow-speed operation.

Specifications:

  • Sierra cross-reference: 18-4457
  • UPC: 840080487359
