GROCO 1/2" NPT Bronze 90 Degree Pipe to 1/2"-5/8" ID Hose

The GROCO 1/2" NPT Bronze 90 Degree Pipe to 1/2"-5/8" ID Hose fitting is engineered for marine, industrial, and plumbing applications where reliable fluid transfer and directional flow control are essential. This 90-degree elbow connector bridges rigid NPT pipe threads to flexible hose connections, making it ideal for tight spaces, engine cooling systems, fuel lines, and hydraulic installations where straight-line routing is impractical. Professional technicians and DIY builders choose this fitting for its proven durability and seamless integration into existing piping systems.

Constructed from C83600 bronze, this fitting delivers superior corrosion resistance in saltwater and freshwater environments—a critical advantage over cast iron or mild steel alternatives. The male NPT (National Pipe Thread) connection on one end accepts standard pipe fittings with a secure, tapered thread seal, while the opposite end features a barbed hose port sized for 1/2" to 5/8" inside diameter hose. UL Listed to standard 647B, the fitting meets safety certifications for pressure applications and is rated for standard flow volumes, ensuring predictable performance under normal operating conditions without excessive pressure drop.

This elbow connector excels in marine engine cooling systems, hot water circulation, bilge pumping, and industrial fluid transfer lines where the 90-degree angle prevents kinks and reduces turbulence. The compact 3 x 1 x 3 inch footprint fits confined engine bays and locker spaces without requiring bulky adapters. Installation is straightforward: apply thread sealant tape or pipe dope to the NPT threads, then secure with a wrench; slide the hose onto the barbed end and secure with a stainless steel hose clamp for leak-proof performance. Compatible with both metallic and synthetic hoses rated for the same pressure class.
