In-line Ball Check Valve - Stainless Steel 316 One Way (SS316, 1/4"NPT MxF)

Good check valve. Cracks at about 10 psi. Reseats well. Two piece construction if you want to open it up to swap springs to adjust cracking pressure.

One of the best built check valves I've ever seen. Worthy of more stars if I could give them. I've been an engineer and a tool and die maker for an excess of 40 years and this is some of the finest quality I've seen.

Very nicely made check valve. Bubble test showed no reverse leak.

I ordered a air lift air management system for my car and found that the check valve with the compressor are junk , these are great and look much better than the ones I got with my new system

I’ve only had it installed for a couple weeks. But it’s way better than the previous 9 that I’ve tried. Yes 9. 5 were from the manufacture of the compressor system that failed within days or were already bad. They just blamed the install. 🙄This is for a car air suspension system so it’s a 0 fail product for me. Car is un drivable if it doesn’t hold air in tanks. Thankfully this installed without issue and easily holds my 200 psi system.It’s also bigger and more robust than all others I’ve tried. I’m glad I found them. Just hope they hold up through winter well.

I've had these on a CO2 line less than one month and two have already failed. Wish I could leave negative stars.

Well built.

Superb product! Exactly as advertised!!
