This 2-1\/2\" male NPT x 2\" female NPT bushing allows you to connect a 2\" female-threaded fitting or hose barb into a 2-1\/2\" male-threaded port — a common requirement when adapting between different pipe sizes in bilge, raw water, exhaust, or through-hull plumbing runs.\u003c\/p\u003e\u003cp\u003eMachined from solid brass, this bushing resists corrosion in both freshwater and saltwater environments and provides a leak-free threaded connection when properly sealed with marine-grade thread sealant. The NPT (National Pipe Taper) thread form creates a pressure-tight seal as the fitting is tightened.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSize: 2-1\/2\" male NPT x 2\" female NPT (reducer bushing)\u003c\/li\u003e\n\u003cli\u003eMaterial: Solid brass — corrosion-resistant in freshwater and saltwater\u003c\/li\u003e\n\u003cli\u003eNPT thread form — tapered threads for a pressure-tight seal\u003c\/li\u003e\n\u003cli\u003eSuitable for bilge, raw water, exhaust, and general marine plumbing applications\u003c\/li\u003e\n\u003cli\u003eUse with marine-grade thread sealant (PTFE tape or pipe dope) for a leak-free connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBest Use Case\u003c\/h3\u003e\u003cp\u003eBest suited for adapting a 2-1\/2\" threaded port or fitting down to a 2\" connection in marine plumbing systems — common in bilge pump discharge lines, raw water intake plumbing, exhaust systems, and through-hull fitting installations. Always use a marine-grade thread sealant on NPT connections. Do not overtighten — NPT threads seal through taper engagement and excessive torque can crack brass fittings.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eBrass reducer bushings are a frequent special-order item for customers doing plumbing repairs or upgrades on older vessels where non-standard pipe sizes were used. When a customer needs this size, confirm whether they need male-to-female (bushing) or female-to-female (coupling) configuration before ordering.
