Repairing Hose Quick Disconnects
Hi, everyone. ItÂs the Annual Replacement of Hose-End Washers Festival for six 3/4" garden hoses at our house, and IÂve just been exercising my arthritic hands in a vain effort to introduce a male, solid brass quick disconnect into its female counterpart.
For those of you who understand what IÂm talking about, I know you share my pain. On the other hand, despite my advanced age it occurs to me that there must be still be something about the mating process that I canÂt comprehend, i.e., how in the #$@& can this be made the simple, straightforward performance that all mammals know and love?
Consider the mating procedure for real quick disconnects. (I mean REAL QDs made of solid brass, not the mewling, slack-jawed, limp-wristed, plastic / piddly brass pot metal masterpieces of contemporary American engineering design.) In these, the male nozzle enters the female port and, before it can be snapped into place by the three spring-tensioned ball bearings which engage the recess at its far end, the muzzle of the nozzle encounters the rubber washer which provides the water seal for the female QD at its hose-end.
Now, if I understand correctly, that washer also provides a water seal for the muzzle end of the male nozzle. In an ideal world, that washer is designed by Goldilocks: not too thick, nor too thin, nor too loose, nor too firm, but J-U-S-T right. It expands and deforms by just the right amount to accept, yet effectively seal, the muzzle of the male nozzle, when "click," a watertight junction is made.
So why, after a dutiful application of the 3 Ps (Patience, Persistence, and Profanity), do I have such a hard time getting the little darlings to mate? IÂm guessing the washers and/or o-rings commonly available at our friendly neighborhood building super-suppliers are not of the correct dimensions. Can this be? Or is there something IÂm missing? In short, how do yÂall git Âer done?
(You M60 and Abrams tankers need not reply with the "If it doesn't fit, force it" routine. BTDT.)
