Overview
The Grainger 5A252B is a 1/4″ male lock barb hose fitting engineered for secure attachment and quick coupling in fluid transfer lines. Lock barb fittings combine a barbed stem with an internal locking mechanism, allowing connections that resist accidental disconnection while remaining easy to install and remove when needed. This lot of 7 units provides multiple fittings for production runs, maintenance inventory, or system expansion.
