I'm not asking for advice on the best ones. I had the best one, but it "broke". By broke, I mean it came apart while strapped to my bike and I lost a couple of small pieces.

Fast forward to a few weeks ago. I bought a mini pump (local bike shop brand, seems a lot like topeak or road morph style ones) with a similar attachment. The attachment mechanism I lost is a reversible presta/schrader grommet and a plastic cap that screws on. Just for kicks I tried putting these onto my old pump. It was a perfect fit. Now, instead of throwing a pump out, I'd like to replace the little bits ($.23 worth of materials at most), but don't know where to get them. I suppose I could call a big brand company, but maybe someone knows more than I about the availability of these bits (or if this attachment has a special name).

Doesn't look anything like my pump, except the very end where it attaches to the presta valve. It's the "reversible grommet" that makes it compatible.

Sorry for the ramble, maybe someone knows what I'm talking about.
