The Series 5505-SS 45-Degree Angled Female NPT x Female NPT Rigid adapters, made from high-quality stainless steel, are designed to provide durable, leak-free connections in fluid and gas transfer systems. These adapters feature female NPT (National Pipe Tapered) threads, a U.S. standard that uses tapered threads to create a tight seal when the male and female components are connected, ensuring an effective seal to prevent leaks. The nominal pipe size can be determined by measuring the thread diameter and subtracting 1/4". These adapters are ideal for high-pressure applications, offering the strength and corrosion resistance of stainless steel. The 45-degree angle enables flexible installation, making these adapters suitable for a wide range of industrial applications where reliable, high-performance connections are required.
