Check Valve- different from NB, costs more?

Kegging

Can I make my own check valve from stuff at a big box store?

My local homebrew shop wants $11 for a check valve for a keg, but it looks different than the NB check valve for $2.50 ?

How about links to the things you are referring to. That would help a lot for us to wrap out minds around your question.

Please.
