and Park Tools pumps?

every few months the valves off the tunes are broken off after removing the pump head. This has never happend with any other tube/valve.

Now the park pump head is hard to get on, but only the michelin latex tubes valves break.

Anyone?

Jeez, how far on are you pushing the pump head? I've got a Park floor pump, and it's a doddle to put on. I've never had a valve issue, although I've never used Mich latex tubes. I've used Mich butyl tubes, but all my tubies have latex tubes in 'em.....You know that the pump head isn't supposed to deepthroat the valve stem, right? :yikes:

LOL! It's not on there too far, put I must open the valve core a bit and get it down the valve a small bit to get the pump to air it up. This is the second valve from park that I have tried.
