Automotive** A: Sorry,it works for fulids.So it won't work for a vaccume pcv . **Q: Can this be used on a submersible 600gph water pump for the basement?** A: no! you can't flow 600 gallons per minute thru this 1/2" fitting. if you get a much larger one then it would work. They make pvc check valves for that amount of flow that come with hose barb and or pvc pipe connections. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars These work GREAT! *by J***R on Reviewed in the United States on August 27, 2024* Worked so well, I ordered another one! 5 Stars!!! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Better than I thought *by A***R on Reviewed in the United States on September 22, 2024* Felt very cheap but still using it six months later ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Used for brake booster check valve *by G***E on Reviewed in the United States on January 10, 2024* I used this as a replacement for a brake booster check valve.
