Sierra 18-4461 Brass Hose Barb Fitting, 3/4 Inch NPT x 1 Inch Hose, Replaces Mercruiser 22-807155, GLM 13984

The Sierra 18-4461 is a corrosion resistant brass hose barb fitting sized 3/4 inch - 14 NPT threads to a 1 inch hose barb. It is used to connect exhaust manifold plumbing and cooling hose runs, and appears in the Chrysler inboard exhaust manifold parts range alongside related mounting kits, manifold gaskets, spacers, and elbows. The fitting is machined from brass for corrosion resistance in a marine environment, making it suitable for saltwater and freshwater engine cooling and exhaust water circuits where a threaded NPT connection needs to step down to hose.

This part is a direct fit replacement for several OEM hose barb numbers used on Mercruiser and GLM applications, letting an installer swap in a Sierra part without hunting down the original manufacturer's fitting. Each Sierra part is built to meet or exceed the original equipment part it replaces. At 0.17 pounds, it is a light, compact brass component intended to thread directly into an existing NPT port.
