Works for windshield washer fluid.
Worked well for a replacement for my windshield washer fluid line in a Ford Flex.

Great price, not greatest quality
The price is really good for the amount of them you receive but the the quality definitely shows for the price you pay. So if you want something more durable I recommend spending a few more but if you looking for a quick fix and quantity then this I definitely recommend:)

Not suitable for 1/5 hp spa applications
Not able to use in my hot-tub ozone intake. The suction needed to overcome the spring force of this directional valve was more than my system could provide. This valve wouldn’t allow ozonated air to pass. My spa uses a small 1/5 hp circulation pump that has very little suction. This one-way valve would not flow. It took all my breath to operate this valve. Valve appears to be good quality. Just not good for my application. I kept the valves but if I had know there suction requirements, I would not have purchased them.

Flow Restrictive
They work. However, they take much higher pressure to open than advertised. They are also very restrictive to flow.

Fixed my camper
05 Rockwood. When I would turn on city water. Water would pour out the back under neath overflow. The water pump for the holding tank has an internal check valve that failed so I put this in the line and fixed it.

Not ozone resistant
NOT suitable for ozone injection systems. Disintegrated after 6 months of use on an ozone injection system for a residential water softener.

Works.
This was exactly the valve I needed to put inline with the water pump for the condensation from my furnace. Been in place for a year now. Still working.

Junk and not new
Complete junk, very high pressure necessary for it to open, makes a huge restriction to flow and on top of that, one of the four delivered was clearly a used product, scratched and torn
