T-H Marine Flush Mount Scupper Valve Assembly - Black - Fits 1 to 1-1/4 in / 1.5 in Thru Hull

T-H Marine flush mount scupper valve assemblies provide a clean, low profile way to manage deck and cockpit drainage on many styles of boats. Each assembly uses a flexible thermo-plastic flapper that stands up to sun, salt, and common marine chemicals without curling, rotting, or losing its seal, so drainage stays consistent over time. These flapper style scuppers are designed to mount over 1 to 1-1/4 inch drain tubes or directly to a 1-1/2 inch thru hull using four screws. A universal hole pattern and grooved interior let the housing fit securely over typical drain flanges and make it a practical retrofit for many existing rubber flapper assemblies. Boat owners can update worn OEM scuppers with a durable, curl proof design that installs quickly with basic tools. Use these assemblies on bay boats, center consoles, pontoons, and other deck layouts where reliable drains are important to comfort and safety. Multiple ring and flapper color options allow you to match surrounding hardware and trim for a finished look. Each unit is sold individually so you can replace a single scupper or outfit both sides of the cockpit as needed while maintaining consistent performance across your drainage system.
