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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-4461\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Hose Barb Fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined, corrosion resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/4 inch - 14 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Barb Size:\u003c\/strong\u003e 1 inch hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 1 x 4 x 5.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Category:\u003c\/strong\u003e Chrysler Inboard Exhaust Manifolds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e GLM 13984, Mercruiser 22-807155, 22-866725, 22-863804, 22-45084\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eListed within the Chrysler inboard exhaust manifold parts range as a 3\/4 inch NPT to 1 inch hose barb fitting.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eGLM 13984;
