Johnson Pump Bulkhead Fitting 3/4" Hose

The Johnson Pump Bulkhead Fitting 3/4" Hose (part number 09-10616) is a marine-grade throughhull connector engineered for reliable seawater intake and discharge applications. This bulkhead fitting serves as the interface point where 3/4-inch hose connects to hull-mounted fittings on recreational and commercial vessels, providing a secure, watertight seal that prevents leakage at the critical junction between interior piping and external seawater systems.

Johnson Pump is a recognized manufacturer of marine sanitation and cooling systems, and this bulkhead fitting is designed to withstand the corrosive environment of saltwater exposure and the pressure cycles of active marine pumping systems. The 3/4-inch hose compatibility aligns with standard marine cooling loop and waste discharge configurations, making it suitable for retrofit or replacement on existing Johnson-equipped vessels. The compact 4x3x4-inch footprint allows installation in tight engine compartments typical of cruising sailboats and powerboats where space efficiency is essential.

This fitting is intended for boat owners, marine technicians, and liveaboard operators who maintain Johnson raw-water cooling systems or integrated waste-handling systems. Whether replacing a corroded fitting on a cruising vessel or assembling a new through-hull installation, this bulkhead connector ensures continuity between hose sections and hull penetrations. The Johnson part number 09-10616 is the OEM-specified component for 3/4-inch applications, making it the correct replacement for systems originally equipped with this configuration.
