The VALUE COLLECTION 6HB3X21/2 is a stainless steel hex bushing with NPT end connections, designed to reduce pipe size between two threaded fittings in a piping system. The hex profile allows a wrench to apply proper torque during installation, ensuring a secure, leak-free joint. Stainless steel construction provides corrosion resistance suitable for demanding fluid and gas service environments. This fitting is a standard component installed by licensed plumbers and pipefitters in both new construction and retrofit applications where pipe diameter transitions are required.
This hex bushing is suited for residential and commercial plumbing, HVAC hydronic systems, and general industrial piping where NPT threaded connections are specified. It is commonly used in mechanical rooms, equipment rooms, and process piping runs to transition between different pipe sizes. The NPT thread standard ensures compatibility with the broad range of NPT-threaded valves, fittings, and pipe nipples used across the trade.
Designed as an OEM-style replacement or new-installation hex bushing for standard NPT threaded pipe systems across plumbing, HVAC hydronic, and general industrial piping applications.
Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC requirements. Always depressurize and drain the system before removing or installing threaded fittings. Apply an appropriate thread sealant or PTFE tape to male NPT threads before assembly. Do not overtighten, as stainless fittings can gall under excessive torque.
