REDUCING ADAPTOR - NPT X NPT (REF. 5405)
REDUCING ADAPTOR - NPT X NPT (REF. 5405)
The Reducing Adaptor – NPT x NPT (Ref. 5405) is a precision-engineered threaded fitting designed to connect two NPT (National Pipe Taper) threaded components of different sizes. This adaptor features NPT male threads on both ends, with one side being larger and the other smaller, allowing for a reduction in pipe size while ensuring a secure and leak-tight connection. Its high-quality construction and precision-machined threads provide a reliable and durable solution for transitioning between different pipe sizes without the need for additional adapters. Manufactured from Stainless Steel, Brass, Duplex, Monel, and Hastelloy, the Reducing Adaptor – NPT x NPT (Ref. 5405) is built to withstand high-pressure, high-temperature, and corrosive environments, making it ideal for industries such as oil & gas, chemical processing, pneumatic systems, and fluid handling. It is available in a range of sizes, typically from 1/8” to 2” (Imperial) or 3mm to 50mm (Metric).
