Pressure Tolerances

I stepped onto the damp brick pavers where a solid brass hose quick-connect fitting rested beside a coiled garden line. Gripping its knurled outer collar with both hands, I applied backward leverage against the internal spring. The heavy brass sleeve retracted smoothly, exposing three polished steel ball bearings seated within the locking groove. When I disengaged my grip, the collar snapped forward into its locked detent with a sharp, resonant click. Any dependable conduit depends on such flawless mechanical tolerances. The coupling stands ready to sustain high pressure without failure.
