ADAPTOR - NPT X NPT (REF. 5405)

ADAPTOR - NPT X NPT (REF. 5405)

The Adaptor – NPT x NPT (Ref. 5405) is a high-quality, precision-machined threaded fitting designed to connect two NPT (National Pipe Taper) threaded components. With NPT male threads on both ends, this adaptor ensures a secure, leak-tight connection between components of the same NPT thread standard. The versatile design makes it ideal for extending pipe runs, making system connections, or transitioning between NPT-threaded components in various industrial systems. Constructed from durable materials such as Stainless Steel, Brass, Duplex, Monel, and Hastelloy, the Adaptor – NPT x NPT (Ref. 5405) is available in a variety of sizes from 1/8” to 2” (Imperial) or 3mm to 50mm (Metric). Its high resistance to corrosion and pressure makes it ideal for use in harsh environments, including oil & gas, chemical processing, water treatment, pneumatic systems, and fluid handling applications.
