I have a Stapley Coe Style B compound (2 stage)hand tire pump, which I believe is all original. There is no check valve in this pump and the hose end that screws on to the tube stem does not have a protrusion to unseat the valve stem. Is this correct? It seems to me that it would take considerable pressure to unseat the valve stem on each stroke, but without a check valve in the pump that seems to be the only way the pump can function. Your thoughts please? jb

I can't comment on what is correct, but if you just want the pump to work, the vendors sell an add-on check valve that fits on the air line. I put one on my single tube pump and it works fine.

Thanks, Mark. I looked at those too. I am still curious if pumps like mine worked without the check valve. I connected my rebuilt pump to a tubeless stem with valve stem in place and the pump would unseat the valve but it took some effort. This pump will be a wallhanger for now. best, jb

I have several handpumps and they all have this small check valve.
