The Series IHC Straight Female NPT x Female NPT Hex Coupling Adapters, made from high-quality 316 stainless steel, are designed for use in instrumentation and other fluid power systems where secure and leak-proof connections are critical. These adapters feature female NPT (National Pipe Tapered) threads on both ends, allowing for easy and reliable connection between two male NPT fittings or pipes. The hexagonal shape of the coupling ensures easy installation and removal with a wrench, while the tapered threads provide a metal-to-metal seal that prevents leaks and maintains pressure integrity in demanding applications. Commonly used in industries such as oil and gas, chemical processing, and fluid handling, these durable adapters are essential for maintaining system performance and reliability.
