The head on my Zefal Husky floor pump won't hold an airtight seal between the pump head and a schrader valve or presta adapter anymore. The Zefal website says there's supposedly a replacement rubber ring available, or replacement head but I can't find anyone who sells those. So, I either need to find a compatible pump head or hose. Has anyone found a U.S. source for Zefal pump parts, or used/adapted a head or hose from another manufacturer's pump on a Zefal? Let me know.

Thanks,
Rich

I believe this place (XX Cycle) ships anywhere including the US - here's a link to the Zefal Husky parts page.

I have used the Topeak replacement head & hose which is more readily available on three different brands of floor pumps so it may do fine on your Zefal.

Did you already tighten the outer ring a little bit that adjusts the diameter of the hole to make up for this common problem?

When this happened on my speclialized pump I upgraded to a new head. I got a Blackburn head which fits presta and schraeder valves, which is handy on the rare occasions when it's needed. It screwed straight into the Specialized base, which would suggest that I was either lucky or manufacturers tend to use the same size for hose attachments.
