<div>I go to grainger or whomever and order one of those
assortment kits if I'm not sure what size I need. Which for me
is everytime, I have no idea how you would even measure one. </div>

<div>The o ring sealing surfaces need to be completely clean and
smooth. Something as small as a human hair across the surface
provides a leakage path. If you have shreds of rubber in
there, then time to clean and inspect. Lubricate if
indicated. If the metal is gouged, then repair or replacement
of the fitting is indicated. </div>
