    does it's job
  

*by J***. on Reviewed in the United States 🇺🇸 on April 2, 2019*

would be nice for more basic direction in details, like a label stating which end is upstream vs. down.

### ⭐⭐⭐⭐ 







  
    Es un buen producto
  
  

*by B***M on Reviewed in the United States 🇺🇸 on August 1, 2019*

Es muy fácil de  adatar y fusiona bien

### ⭐⭐⭐⭐⭐ 







  
  
    Very low seat pressure
  

*by A***Y on Reviewed in the United States 🇺🇸 on February 16, 2019*

These work very well. I use them for crankcase ventilation systems. They have a very low "pop off" seat pressure (not measured, but under 1psi for sure. A soft blow gives you full flow) which makes them ideal for crankcase ventilation without a vacuum source. Check valve sealing is good too. Flapper appears to be rubber, nitrile, or neo rubber, so keep them away from heat sources.Great alternative to the moroso scavenge valves if you dont need a threaded end
