GROCO 1-1/2"" NPT x 1-1/2" ID Stainless Steel Pipe to Hose Straight Fitting

The GROCO 1-1/2" NPT x 1-1/2" ID Stainless Steel Pipe to Hose Straight Fitting is a precision fluid transfer component engineered for potable water systems and marine applications where corrosion resistance is non-negotiable. This straight fitting connects NPT male threads to hose barbs using marine-grade #316 stainless steel, eliminating galvanic corrosion concerns in salt-air environments and ensuring long service life in demanding saltwater or freshwater systems.

Built to NSF-61 certification, this 1-1/2" fitting meets strict drinking water safety standards, making it compliant for use in potable water plumbing and pressurized systems. The #316 stainless steel construction resists pitting and crevice corrosion far better than standard 304 stainless or brass alternatives, a critical advantage in coastal, high-chloride, or chemically aggressive environments. The straight design ensures minimal flow turbulence and straightforward installation without sharp bends that create stress points or restrict water velocity.

This fitting serves marine plumbing systems, offshore equipment, desalination installations, and any application where stainless-to-hose transitions must withstand repeated thermal cycling and salt spray exposure. GROCO is recognized in the marine industry for precision bronze and stainless fittings that meet or exceed Coast Guard and international maritime standards. The 1-1/2" size handles standard flow rates in galley, head, and cooling water circuits on vessels ranging from commercial fishing boats to offshore platforms.
