I purchased these for a hot water recirculating project. They connect directly to a standard 1/2” faucet connection that use a sealing washer to seal.Great value! Works perfectly with some precautions. Do not over tighten. I recommend tightening by hand then check for leaks. Then tighten with wrench until leak stops. Then tighten an extra 1/8 to 1/4 turn. That’s it.Also do not use with PEX type female fittings. See pictures. The internal portion of the PEX fitting will contact and crush or push out the check assembly inside the check valve.

The threads are loose and the fitting bottoms out. Leaks steadily even with copious wraps of Monster pipe thread tape that's worked flawlessly with hundreds of other fittings.

I used this for an airline to connect the compressor to the tank. The inside is plastic as you can see. It's rather small diameter given it's 1/2" NPT size. The actual hole is maybe 3/8" at best. It makes a little bit of a whistle when air goes through it. There's no CFM ratings so I have no idea if it's reducing or not but it still seems to work.I don't trust check valves so I put a quarter turn valve on the tank side, then this check valve so I can just shutoff the tank as needed. If you don't know how check valves work they allow flow in 1 direction only. This goes on the compressor line to keep tank filled even if there's pressure loss in the pump, the tank won't drain. Nearly all pumps will lose pressure due to their design. So most air compressor systems need a check valveThis item has good pics to show flow direction and the NPT fittings are shown and accurate. The inlet side is the FIP and the outlet is the MIP. There's also 2 in the package.

One is working fine, but another one has some leaking, or water running back after shotdown the valav. Overall its still good for the money.

Used this inline check valve on a new air compressor build. The valve body is brass, painted black. The internals are a white plastic ball & seat, possibly nylon. Female thread uses rubber gasket to seal your fitting to the check valve vs standard NPT tapered threads. There is slight leakage, IE: tank pressure drops from 120 psi to 100 psi over 2 day period. I need to soap-test connections to determine if the gasket or the check ball is the cause of leakage.FOLLOW-UP INFO:On disassembly, the check part of the valve had separated and wedged in a fitting. The spring was no where to be found. (Valve on right in photo. The white part is the ball portion). Installed the 2nd check valve thinking the 1st failure was a fluke. Not so - it also failed within a few minutes of operation. (Valve on left in photo). In the 2nd failure, check ball was no where to be found. Spring is still in valve. At this point, both valves are unusable.MORE FOLLOW_UP INFOUpon reading my review, the seller quickly reached out for a solution, I decided on a refund and the full price including tax was refunded the same day. In addition, the seller followed-up 2 days later, asking for me to verify that the correct amount did post to my credit card-which it had. I much appreciated the sellers actions and follow-up. They are a 5-star stand out amongst Amazon retailers.
