The Series IHRC Straight Female NPT x Female NPT Hex Reducing Coupling Adapters, crafted from high-quality 316 stainless steel, are designed to provide secure and leak-proof connections in instrumentation and fluid power systems. These adapters feature female NPT threads on both ends, with one side having a reduced size to accommodate different pipe diameters. The hexagonal shape of the coupling allows for easy installation and removal using a wrench, while the tapered threads ensure a reliable metal-to-metal seal that prevents leaks and maintains pressure integrity. These versatile adapters are ideal for applications where size adjustments between pipes or fittings are needed, making them essential for industries such as oil and gas, chemical processing, and fluid handling.
