The only weak link I can find with these pumps, is the ability of dirt and grit to get in the air chuck.

If you see dirt in your Topeak Road or Mountain Morph Pump, there is a cheap, easy, fix.

Ace Hardware has some small "Tips" , for chair and table legs that fit perfectly, sealing the unit, so it will work when you need it. They fit just snuggly enough to stay on well, and are able to be removed without difficulty. It is made of black flexible plastic, which looks like it belongs there. (Other sizes are also available for other pumps/chucks.)

Item # 56927, "Tips", 5/8". 16mm, 4 pcs per card, for less than $2. You can get them at your local Ace, or on the net, on the Ace Hardware website.

I know mine gets dirty; but, it won't any longer....,

Nice tip. May have to give it a try if I remember the next time in the hardware store.

I vouch for these. I picked up a card of four pieces last night and they fit perfectly.
