The VALUE COLLECTION 6BN21/2X4 is a stainless steel pipe nipple machined to Schedule 40 wall thickness with NPT (National Pipe Taper) threads on both ends. It provides a pressure-rated, corrosion-resistant threaded connection between pipe fittings, valves, and equipment in fluid or gas piping systems. The Schedule 40 designation means standard wall thickness suitable for a broad range of working pressures in commercial and industrial piping. Licensed plumbers and pipefitters install this type of close-tolerance nipple where a short, rigid threaded section is needed to complete a run or transition between components.
This pipe nipple is suited for residential and light commercial plumbing, process piping, and mechanical systems where corrosion resistance is a priority. Stainless steel construction makes it appropriate for applications involving water, steam, mild chemicals, or environments prone to oxidation. It is commonly used in HVAC mechanical rooms, boiler rooms, and process lines where standard galvanized or black-iron fittings would be at risk of corrosion. A single nipple is supplied per package, making it easy to order the exact quantity needed for a job.
Designed as an OEM-style replacement or new-installation component for Schedule 40 NPT threaded piping systems using standard pipe fittings, valves, and couplings.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC codes for threaded piping. Shut off the fluid or gas supply and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the NPT threads before assembly — do not over-tighten, as stainless threads can gall. Inspect threads for damage before installation and confirm the system is leak-tested to the required pressure after assembly.
