3/4 Inch Vertical Check Valve SUS304 Spring Loaded Check Valve in-line Low Cracking Pressure CF8M WOG 1000

I've worked for one of the largest plumbing wholesalers in the Northeast for over 30 years and have seen the good better and best of valving. This swing check is a quality product and worth the money!

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.

I bought 2 and, on both, there's an issue with the threading on the downstream side. With appropriate application of torque it isn't a big deal, but the threads certainly don't slide easily. The upstream side is fine. I checked both with multiple other fittings.

There seems to be a magnet that holds the valve closed when there is no pressure either direction. The holding force releases once open, so it doesn't provide a lot of flow resistance.

dont know what its supposed to check but it wont hold air. didnt work for me and too late to return. gonna eat another junk product.

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

This valve works as described, A+!

I installed it as a check valve on an air compressor. It had a slow leak so I had to replace it. Would probably work well in water system. Looks to be well built and durable.
