GROCO 2" NPT x 2" ID Bronze 90 Degree Pipe to Hose Fitting Standard Flow Elbow

The GROCO 2" NPT x 2" ID Bronze 90 Degree Pipe to Hose Fitting Standard Flow Elbow is a marine-grade through-hull adapter engineered for saltwater and freshwater cooling systems, raw water intake lines, and engine exhaust applications. After years running boats in demanding conditions, any experienced angler knows that corrosion and fitting failure can strand you miles from the dock—this bronze elbow is built to prevent exactly that. Whether you're upgrading an older seawater cooling loop or installing a new raw-water washdown system, this fitting delivers the reliability that keeps your boat running trouble-free.

Cast from marine-grade bronze, the GROCO fitting resists galvanic corrosion far better than brass or steel alternatives—critical when saltwater flows through your engine cooling circuit continuously. The 90-degree angle design allows compact plumbing routing in tight engine rooms and bilge spaces where straight fittings won't fit. NPT (National Pipe Tapered) threads on the inlet mate securely with 2-inch ID hose on the outlet, creating a dual-interface connection that accommodates both rigid piping and flexible hose runs. At 1.4 pounds with compact 3 x 2 x 4-inch dimensions, it integrates cleanly into existing systems without requiring major re-plumbing, and the standard flow rating ensures no throttling of water delivery to your engine's heat exchanger.

This elbow suits cruising boats, commercial fishing vessels, and cabin cruisers that rely on through-hull cooling systems to stay operational in saltwater or brackish environments. Owners installing new engine cooling loops, upgrading legacy fittings, or repairing corroded through-hull adapters will find this GROCO fitting outlasts cheaper alternatives by years. Installation requires NPT-compatible hose clamps and hose rated for marine use; ensure all hose connections are double-clamped per ABYC standards. Compatible with standard 2-inch marine hose and NPT-threaded through-hull ports, it's the replacement choice trusted by marine technicians and weekend boaters alike.
