Has anyone replace the "Chuck" on their floor pump?
 

I have a pretty-much-other-wise-okay floor pump, the rubber in the Chuck has worn.
I feel there should be a way to replace this, is there? Its an "Auto Dual Valve" But would be fine to make it Presta only.

Unscrews from hose...


Fifteen min later, Edit: Park tool helped me find their fix-it page:

They also sell the replacement heads,
but not the little gaskets which would be cheaper to replace than the whole head.


cool beans

If you are going to make it presta only just get a silca chuck. Will last easy 10 years before you need a new rubber.

The Hirame is the ultimate. But cost is high. Approx $75.

Yep. Btw, the threadless stems are kinder to the gaskets in the head.
