GROCO 1-1/4" NPT x 1-1/4" ID Bronze Pipe to Hose Straight Fitting

The GROCO 1-1/4" NPT x 1-1/4" ID Bronze Pipe to Hose Straight Fitting (PTH-1250) is a durable marine and industrial plumbing connector designed to join NPT threaded pipe to flexible hose in applications requiring reliable, corrosion-resistant performance. This fitting is ideal for saltwater environments, bilge systems, engine cooling circuits, and pressurized water delivery where bronze's superior seawater compatibility outperforms ferrous metals. The straight configuration allows direct, leak-free transitions without direction changes, making installation straightforward in tight spaces or linear runs.

Constructed from C83600 bronze—a high-strength, corrosion-resistant copper alloy—this fitting resists dezincification and stress corrosion cracking in harsh marine conditions where standard brass would degrade. The male NPT (National Pipe Thread) connection on one end mates with standard tapered pipe threads, while the 1-1/4" ID hose barb on the opposite end securely grips reinforced hose with a stainless steel hose clamp. UL Listed under standard 647B, the fitting meets stringent safety and performance benchmarks for marine and industrial use, and its standard flow design minimizes turbulence and pressure drop across the connection.

This fitting is best suited for marine engine cooling systems, seawater intake lines, bilge pumps, and industrial fluid transfer applications where reliability in corrosive environments is non-negotiable. The 1-1/4" size accommodates moderate to high flow rates while maintaining compact dimensions (2 x 2 x 3 inches) for versatile installation. Pair with 1-1/4" ID hose and stainless steel hose clamps to ensure long-term watertight service; the lightweight bronze construction (0.45 lbs) is ideal for weight-conscious marine applications.
