Moeller Brass Bulkhead Fitting, Straight 3/8 Inch NPT Barb Connector

This Moeller brass bulkhead fitting is a straight, 3/8 inch fuel line connector designed to pass fuel line through a bulkhead or tank wall while maintaining a secure, leak-resistant seal. Built from solid brass with a brass exterior finish, the fitting resists corrosion in the marine fuel system environment and holds up to repeated hose connections over time. The barb-style connector end accepts 3/8 inch fuel hose, while the threaded side uses a 0.375 inch NPT thread for a tight, sealed installation into a bulkhead, tank fitting, or fuel line junction.

This fitting is a single-piece component intended for use in boat fuel systems where a fuel line needs to pass through a bulkhead, transom, or tank wall. It is commonly used when running or replacing fuel lines on boats equipped with portable or built-in fuel tanks. The compact, straight design keeps the fuel line routing simple and minimizes strain on the hose at the pass-through point. As a Moeller product, it is built to the same fuel system design and construction standards the brand is known for in marine fuel components.
