Centek 1200299 3" Marine Exhaust Thru-Hull Fitting with Flapper - Black

The Centek 1200299 is a 3-inch marine exhaust thru-hull fitting designed for reliable underwater exhaust discharge in boat applications. This black composite fitting features an integrated flapper valve that prevents water backflow into the exhaust system when the engine is off, providing essential protection against flooding.

Key Features:

• 3-inch diameter exhaust outlet for medium to large marine engines
• Integrated flapper valve prevents water intrusion and backflow
• Durable black composite construction resists corrosion in saltwater environments
• Designed for below-waterline exhaust installations
• Compatible with Centek water lift mufflers and exhaust systems

This thru-hull fitting is engineered to withstand the harsh marine environment while providing a secure, leak-free connection point for your vessel's exhaust system. The flapper design allows exhaust gases to exit while automatically closing to block water entry, making it ideal for installations where the exhaust outlet sits below the waterline.
