Nashbar Bike Pump Problem
I have this Nashbar pump and I never had this happen before. I place the chuck on the presta valve and when I lock it and start to pump, the air rushes out of it. Useless, as of right now. Just curious about what this could be and the easiest solution is probably to buy a new connection since the hose is fine.
Any recommendations on a valve connection for this?
Thanks

Are you sure the problem is with the chuck? It could be a stuck check valve in the pump itself.

Usually those chucks can be partially disassembled for cleaning. Whenever my Nashbar Earl Grey double-sided chuck misbehaves it's because there's some debris or goop in the chuck because I use latex sealant in the tubes for my errand bike. Or a bit of cat litter, because I have three cats and they drag that stuff around the house -- I've actually found a bit of gritty kitty in the chuck once, possibly because my pesky tabby swats at the hose if I forget to snap the chuck end back into the holder. I unscrew the locking collar and clean out the bits with a cotton swab. Usually does the trick.

Thanks guys for the replies, not sure of how to check for stuck check valve in the pump? I did take apart and just not sure of why air comes out real fast when I am pumping the tire.

It could be a seal around the valve.
I've had pump heads break for one reason or another, usually frame pumps that get an internal crack in them.
Sometimes some grease or margarine/butter will help.
It should be easy enough to replace a pump head. I just replaced one on a mini-compressor because the pin to depress the Schrader valve was broken. And, unfortunately, it was tough finding a pump head I really liked.

Does it leak around the tube stem and will not sit perfectly square to the stem?
It seem to be loose on the stem? Presta?
Does it do this on all tubes or just some?

first place to look is the rubber chuck that engages the valve.
Most parts like this are not repairable, and repair parts not available.
maybe time to buy a new pump ? The silca pumps are fully rebuildable, will last a lifetime.

Went through this with a daughter's Nashbar pump and while a fine pump it is very annoying they do not have seal kit spares as many pump manufacturers do, Blackburn, Topeak, SKS, and others. We were able to get a replacement hose with head for her model, you might try taking it to a bike shop to see if they have a new rebuildable head that would adapt to your hose. Good luck.

Get a $15 smart head with a hose kit. Super easy and universal. I made a video a while back of the process on a 20-year-old pump I had. Works just like new!
