HEX COUPLING - NPT (REF. 5000)

HEX COUPLING - NPT (REF. 5000)

The Hex Coupling – NPT (Ref. 5000) is a high-quality threaded fitting designed to connect two NPT (National Pipe Taper) threaded components in a straight-line configuration. Featuring male NPT threads on both ends, this coupling provides a secure, leak-tight connection, ideal for extending pipe lengths or joining sections of pipe with matching thread standards. Its hexagonal body ensures easy handling and tightening with a standard wrench, facilitating quick and efficient installation, even in confined spaces. Manufactured from durable, corrosion-resistant materials such as Stainless Steel, Brass, Duplex, Monel, and Hastelloy, the Hex Coupling – NPT is available in a wide range of sizes, from 1/8” to 2” (Imperial) or 3mm to 50mm (Metric), making it suitable for a variety of industrial applications. It is commonly used in oil & gas, chemical processing, marine, pneumatic systems, and fluid handling where NPT connections are standard.
