Moeller Marine Brass Bulkhead Fitting, 1/4 in. Female NPT

The Moeller Marine 033435-10 is a brass bulkhead fitting sized for 1/4 in. Female NPT connections, built to pass a fuel line or vent line through a bulkhead, tank wall, or transom panel while providing a secure, threaded connection point on each side. The fitting is machined from brass, a material chosen for its resistance to corrosion in the marine fuel system environment, where constant exposure to moisture, fuel vapor, and temperature swings can quickly degrade lower-grade materials. Its 1/4 in. Female NPT threads on both ends allow it to accept standard 1/4 in. NPT fittings, hose barbs, or fuel line adapters, making it a common connection point in small craft and auxiliary fuel systems.

This bulkhead fitting is typically installed by drilling a mounting hole through the bulkhead or panel, passing the fitting through, and securing it so that fuel or vapor lines can be connected on either side without the line itself passing through an unsealed opening. It is compact, with an item size of 6 x 2.25 x 1.75 inches, and weighs 0.1 pounds, making it easy to fit into tight compartments common on boats.
