    • Air/water seperator
Size: 1/4" NPT Style: 5 μ
Even though this is a small size device, it works very well. I had water running out of my vacuum table due to moisture in my air supply, this device removed the water and then drained itself when I shut off the air.

    • Works great, but poor threads. Needs real Teflon tape and cranked tight.
Size: 3/8" NPT Style: 0.01 μ, Metal Coupler & Plug
This works great for my Husky 60 gallon 155 psi air compressor. It originally leaked even with 5-6 wraps of the included Teflon tape on the connectors, but I eventually replaced the tape with real Teflon tape and cranked the connectors extremely tight and it now takes a week to drop 155 to 100 psi (I installed a ball valve between the tank and this regulator assembly and it doesn't really leak at all when it's closed, so I know it's the leak is from this assemble). I would recommend this, but just know the threads are rough and require a lot of Teflon tape and torque on the wrench. ... show more

    • Leak free and works great!
Size: 1/4" NPT Style: 0.01 μ, Metal Coupler & Plug
Got this to replace a leaky regulator/filter on a 30 year old compressor. Perfect fit, leak free and easy to use regulator. I got a 1/2" to 1/4" reducer to fit the disconnect to for my hose. I picked up a PSI gage to replace the metric one it came with. Great solution for my old air comp and 60 gallon tank. ... show more

    • It works, just not out of the box
Size: 1/2" NPT Style: 5 μ
I replaced an old one that eventually leaked via bad gasket. This one came with a gauge that didn’t fit, an npt plug that wasn’t tapered and wouldn’t seal, and useless thread tape. I was able to reuse the old gauge, had a real NPT plug, and used good thread tape. It works just fine now. Just know it may or may not work with what comes with it. ... show more

    • All around a terrific little system
Size: 1/4" NPT Style: 5 μ
I was really impressed with this unit. All the fittings I needed were included, plumber's tape (though it is really thin), and it came mostly assembled. The way they designed this makes each module interchangeable. I actually removed the module with the pressure gauge to do a pressure test, everything worked perfect without the filters attached. The included instructions are very brief and not translated well. Fortunately everything is marked with arrows for flow on the top of each module and the regulator has indications of how to lock as well increase/decrease pressure. The two reasons I marked this as 4 stars rather than 5: the filter drain valve assemblies and small air leaks. *For my small airbrush compressor, the drain valves do not close by themselves. I have to manually hold them shut in order for the filters to build pressure to hold them closed. Its a little annoying but still functional. *I'm also have issues with the fittings and modules holding pressure (compressor discharge is 57psi rated, gauge shows approximately that). With the supplied plumber's tape and the supplied fittings, I cannot hold pressure. I have a slow leak that short cycles my compressor. All the fittings are tightened except the pressure gauge which is very difficult to get a wrench on due to the small clearance between the gauge and the body. I have hand tightened it as far as I can. Recommendations to the manufacturer: *I would recommend either including a thin wrench that allows you to tighten the pressure gauge or install the gauge at the factory. *I would upgrade the plumber's tape to something a bit more robust. If it leaks at 60psi, I can imagine what others are experiencing. *Change the spring in the drain valves so low pressure/flow compressors can close the valves without manual interaction. ... show more
