Unit worked until it didnt hold pressure within 30 days. Opening the unit up and stretching the spring seems to be a temporary fix. The spring is very weak. See how long it last this time. Seems all units - name brand or otherwise have issues.

This is a very good and well designed check valve. I used this to prevent boost from back feeding to my catch can. It allows vacuum to be pulled at idle and prevents pressure from pressurizing the can when under boost. Tested up to 23psi and holds with no issues. This is NOT a pcv valve replacement if you’re thinking about that, it will for sure allow too much vacuum to be pulled if you do that, just an FYI. This check valve works exactly how I needed it to. Great seals and internals are a much better design than most I’ve seen.
