GROCO 2" NPT x 2-1/4" Bronze Full Flow Pipe to Hose Straight Fitting

The GROCO 2" NPT x 2-1/4" Bronze Full Flow Pipe to Hose Straight Fitting is a marine-grade fluid transfer component engineered for high-capacity flow applications where pressure drop and weight matter. This fitting connects 2-inch NPT (National Pipe Thread) male ports directly to 2-1/4-inch diameter hose with a straight, full-flow design that minimizes turbulence and maintains system efficiency in demanding saltwater and freshwater environments.

Constructed from C83600 bronze—an alloy specifically formulated for corrosion resistance in marine service—this fitting delivers superior durability in offshore, coastal, and freshwater applications. The full-flow geometry eliminates restrictive elbows and reduces backpressure, critical for cooling systems, bilge pumps, fuel transfer, and raw-water cooling lines where flow capacity directly impacts engine performance and system reliability. The fitting is UL Listed to Standard 647B, confirming its suitability for marine pressure systems. Weighing just 1 pound, it adds minimal system weight while providing a robust, leak-free connection point.

Marine system integrators, boat builders, and offshore equipment operators rely on GROCO fittings for mission-critical fluid management. This 2-inch straight fitting is particularly suited to transom-mounted heat exchangers, engine cooling manifolds, and through-hull seawater systems where space is confined and flow must remain unobstructed. The NPT x hose configuration allows seamless integration with both rigid piping headers and flexible hose runs, a common requirement in retrofit and new-build marine installations.

Important: C83600 bronze fittings do not comply with NSF-61 standards and are not approved for use in potable (drinking) water systems. This fitting is engineered exclusively for cooling systems, fuel systems, and non-potable fluid transfer in marine applications.
