The DIXON VALVE COUPLING DV-00340 is a steel threaded nipple designed for hose coupling applications in fluid transfer systems. This combination nipple provides a secure, threaded connection point between hoses and piping or equipment. Constructed from steel for durability under pressure and mechanical stress, it features NPT threading to ensure leak-resistant sealing with standard NPT-compatible fittings and adapters. It is typically installed by plumbers, pipefitters, and industrial maintenance technicians in fluid handling and distribution setups.
The DV-00340 is suited for use in commercial and industrial plumbing, fluid transfer lines, and hose assembly applications where a reliable NPT-threaded nipple connection is required. Its steel construction makes it appropriate for environments where strength and resistance to mechanical wear are priorities. Sold individually, it fits into standard hose coupling assemblies and is compatible with NPT-threaded fittings throughout the system.
Designed as an OEM-style replacement or new-installation fitting for systems using NPT-threaded hose coupling components in commercial and industrial fluid transfer applications.
Installation should be performed by a qualified plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off fluid supply and depressurize the system fully before removing or installing any hose fitting. Apply appropriate thread sealant or PTFE tape to NPT threads to ensure a leak-free connection. Do not overtighten threaded connections, as this can damage threads or cause fitting failure.
