HEX NIPPLE - NPT (REF. 5404)
HEX NIPPLE - NPT (REF. 5404)
The Hex Nipple – NPT (Ref. 5404) is a high-quality, precision-engineered threaded fitting designed to connect two female NPT-threaded components in a straight-line configuration. It features a hexagonal body at the center, which allows for easy tightening and installation using standard wrenches. This fitting is widely used in fluid and gas systems where secure, leak-tight threaded connections are essential. Available in sizes ranging from 1/8” to 2” (imperial) and 3mm to 50mm (metric), the Hex Nipple – NPT is manufactured from a variety of durable materials including Stainless Steel, Brass, Duplex, Monel, and Hastelloy, offering excellent resistance to pressure, temperature, and corrosive media. It is ideal for applications in oil and gas, chemical processing, instrumentation, marine, and general industrial systems.
