1/2 Inch Vertical Check Valve SUS304 Spring Loaded Check Valve in-line Low Cracking Pressure CF8M WOG 1000

Time will tell

The 3/4" NPT thread seals to standard 3/4" NPT which many of the other products don't do - either they are not NPT or the manufacturing cuts too deep.This check valve fits and works perfectly, so I recommend it.

This valve works as described, A+!

Doesn’t seal. Wont stay centered. Try a different brand.

The seal is not effectively preventing the passage of fluids, which means that there may be leaks or spills. This can be a serious issue, particularly in situations where the fluids being transported are hazardous or expensive.

This item has a very poorly designed check valve disc. It hangs up often and does not seal completely. Would definitely not recommend

AC condensate drip right on through while eliminating the back draft...Functions perfectly.

Needed a new check valve for my old hand dug well pump. Found it on Amazon. Just what I needed.

as described. good price. fast delivery. would buy again
