Works great
Used it as a one way breather for a fuel tank to allow inflow to offset fuel flow while the engine is running but not allow constant venting, stinking up the garage. The fuel cap has a spring loaded seal if real pressure starts to build up. Works great!

One-way check valves work, but don't last long
I used these to replace the one-way flow valves in both my and my wife's SleepMe Chilipads. These look and function identically. These valves fail pretty regularly, the same as the valves did that came in the units from the factory. I am not sure how long these are supposed to last, but I find I need to replace them about every three months or so, because something happens and the water is allowed to flow back down into the system. These are pretty cheap, and it is pretty easy to change the part in my application, so I am not going to knock them too much. Four stars because I wish they lasted six months instead of three months between failures.
