10 Pack 1/8 inch Plastic Check Valve, One Way Barb Hose Inline Non Return For Fuel, Oil, Water, Air (1/8 inch)

Yes id buy them again. They work as it should

Compré este producto para uso de negocio y hasta ahora mi experiencia ha sido muy buena. La calidad es excelente, el material se siente resistente y cumple perfectamente con lo que describe el vendedor. Es fácil de usar y llegó en buen estado y a tiempo. Sin duda lo recomiendo y volvería a comprarlo.

They are cheap and look cheap but work great. I tried the first one and I saw air sucked in the line (hand soap). Tried the second one with same result and thought the quality of the seal was bad. Tested both with syringe and water and there was no leak with pressure. Turned out my tube was cracked and sucked in air, not the valves.

I'm building my own IOT plant watering system, and these valves are an effective way to prevent back-flow into my mini centrifugal water pumps. The forward pressure required to push water through them in the normal direction is quite low, and they are causing minimal reduction in pressure on the delivery side of the valve. I would use them again.

Had a few give out and allow flow the wrong way. I wouldnt buy these again.
