Thanks for response Tanya. I have since found out that the old O Rings were still on the male brass spout within the groove, but had lost all their elasticity and were hard and flat, so when I was feeling around under the counter, I assumed I was feeling metal, and that the O Ring was missing. I finally figured out the old O Ring was still stuck in the groove. I had to gouge out the old O Ring, and then I could insert a new O Ring RP 13938. Then the quick connect worked fine. No more water leak. Another lesson in O Ring embrittlement.
