Threaded NPT Pipe Adapter
The stainless steel Threaded NPT Pipe Adapter is designed to connect pipes or fittings with differing NPT thread sizes or configurations. Ideal for contractors working in fluid, gas, or steam systems, this adapter provides a secure, leak-resistant transition between components. Made from corrosion-resistant 304 stainless steel, it withstands harsh environments and high-pressure applications. Installation is simple—apply thread sealant and tighten with standard tools to achieve a reliable seal.
SKU: S10031
