Description
This 1/4 inch hex nipple is a threaded pipe fitting used to join two female NPT connections inline on a pneumatic dispensing air supply, such as between a regulator, filter, or valve inlet. It is one of the small dispenser parts that rarely gets attention until a line needs to be reconfigured or a fitting fails, at which point having the right nipple on hand keeps a repair to minutes instead of a full afternoon spent tracking one down.

Dispenser Parts for Air Line Assembly
A hex nipple’s center flats give a wrench a solid grip for tightening without marring the fitting, which matters when the same joint may need to come apart again for future service. Keeping a small stock of common thread-size nipples on hand means an air line reconfiguration or a fitting swap does not have to wait on a parts order, which can otherwise stall a whole dispensing cell for days. Maintenance teams that standardize on 1/4 inch NPT throughout a facility tend to keep a handful of these on hand for exactly this reason.
Where This Part Fits in a Dispensing Setup
This nipple threads into the same 1/4 inch NPT ports used throughout Techcon’s pneumatic dispensing valves, regulators, and gauges in CC’s dispensers, mixers, and nozzles line. It is a straightforward way to extend, join, or reroute an existing air supply run without redesigning the whole line.
