The GROCO 1" NPT x 1" ID Stainless Steel Pipe to Hose Straight Fitting (Model PTH-1000-S) is a precision fluid connection component engineered for marine, plumbing, and potable water applications where corrosion resistance and system reliability are non-negotiable. This fitting delivers a direct transition from male NPT (National Pipe Thread) to ID hose barb, eliminating the need for multiple adapters in fresh water and saltwater environments.
Constructed from #316 stainless steel, this fitting resists corrosion in salt air and chlorinated water systems better than lower-grade materials. The 1-inch NPT male thread accepts standard pipe connections, while the 1-inch hose barb accommodates tubing with a 1-inch inner diameter. Standard flow design minimizes pressure drop while maintaining full throughput capacity. NSF-61 certification confirms compliance with potable water safety standards, making this fitting suitable for drinking water distribution, marine livewell systems, and closed-loop deck wash applications where food-grade contact may occur.
This straight fitting serves boat owners, well system technicians, RV enthusiasts, and commercial water transfer operations requiring a no-bend connection between rigid pipe and flexible hose. The compact footprint and stainless construction eliminate vibration-induced leaks common with dissimilar metal fittings. GROCO's established reputation in marine fluid systems ensures consistent thread pitch and barb sizing across production runs—critical for maintaining system integrity under varying pressure and temperature cycles.
Available in sizes ranging from 1/2" to 3" NPT, the 1-inch version addresses mid-range flow requirements in saltwater cooling loops, agricultural irrigation, and freshwater supply lines. When specifying stainless steel fittings for corrosive environments, #316 grade and NSF certification provide the technical assurance that replacement intervals will be measured in years, not seasons.
