I have a small machine shop. To start out I used regulators from RapidAir. I had three of them and all leaked around the plastic top and eventually around the water bowl.
I run a 3/4 regulator at the compressor so the supply is 120psi regulated down to 100 at the machines. That shouldn't be high enough to cause the plastic tops to

I have used my compressor for sometime without a water separator. I reasoned that draining the tank would be all I needed. I was wrong. I soon grew frustrated with moisture coming out of my blow gun, putting moisture in my car tires (which causes damage to your wheels), and seeing moisture coming out of my pneumatic tools. So I purchased

Worked well for about a year before developing a leak at the pressure regulator knob. Root cause was a torn diaphragm. Contacted manufacturer who diagnosed the issue and sent service kit (PN 104430 or 104431) free of charge/next day air. Product was out of warranty. Really happy with that. The service kit included a diahpragm, washer,

Pros:
Sturdy metal housing.
Wall Mount is built on the unit.
Small profile for home use.
Cons:
Plastic fitting didn't work well with my existing metal fittings.
Recommendations:
If you have extra metal fittings use them instead of the plastic ones included, don't even bother with the plastic ones that

This is the best regulator that i've had the chance to use, it's accurate, maintains pressure and so far haven't had any issues with leaks. I am very pleased with this regulator. During the install I needed to reverse the filter and dryer to accommodate the piping in my garage and it was an extremely easy process to do so. The only

I really like this. I bought it to protect my pneumatic can crusher recently purchased. Any air powered tool needs filtered air and a little oil. The regulator holds great. I would buy it again. I also bought a light air tool oil to use in it. Personally I don't care for Marvel Mystery oil and found a pint of air tool oil that came in a

Regulator and gauge fit perfectly as a replacement for my Central Pneumatic (Harbor Freight Item 69667) 8 gallon compressor. Original was cracked because quick coupler fitting was tightened too much. When changing out I was extra careful when installing fittings. Case is made of "pot metal" and is very susceptible to cracking if

I did not want to spend $80 for an Iwata brand regulator/water separator, so I thought I would try this one. Using the included thread sealing tape, I installed the included pressure gauge and the two 1/4 inch NPT nipples. I hooked up my hose lines and attached it to the air compressor. So far the regulator is working great. It holds

My orginal pressure regulator broke on me suddenly out of the blue.. its just a basic gauge with red knob on the top.

And i needed to have it replaced while doing a little upgrade to it.
Upon browsing the prices ranged for low $10 to around $40s.

I thought I'd never have to buy another since it was I/R, ARO, at least a US company and QA even if made in Korea. Worked OK for a while (about a year) then started to leak at relief anytime tank pressure went below setting. Infrequent use. Sometimes you can get it to stop by raising/ lowering the pressure. Other times (now almost always)

Bought this to repair an older Dewalt/Emglo compressor. It fit fine and was easy to install, unfortunately I couldn't get the pressure relief valve to stop venting (it only stopped venting when the tank pressure and regulated pressure were equal, which is kind of useless). It was a slow leak, so it would have worked in a pinch, but I

As others have stated, the 1/4 NPT threads are overtapped so they will just barely seal--they did seal, though. It's weird that they managed to get the 1/8" NPT for the gauge right.

Some bits of flashing around the casting marks. I cleaned some off and then disassembled it to make sure the pieces weren't floating around

I use this downstream of my onboard air to inflate tires to a chosen pressure without having to hold an inflator trigger the whole time, or risk over-inflating when attaching a hose directly between the compressor and tire. I've put a female coupling on the output, so to set it I plug in my inflator (with gauge) and dial in the pressure I

Bought this to improve air control on my airbrushes. Sometimes I need to use very low air pressures. The regulator on my compressor was impossible to adjust below 10psi with any repeatability. I bought the 3 to 30psi version and put it downstream from the air compressor regulator. I located it so it is at hand while I'm painting. It

I bought this to use with my pressure gauge calibration set-up for calibrating the gauges at a brewery. My old regulator "drifted" far too much, making it very hard to calibrate a gauge. This one works quite well and is stable once you get it to a desired pressure. Ports are the right sizes and locations for my use. This is a relieving

I like the filtering aspect, and the regulator is spot on and doesn't wander away from set point. I never could stop the gauge/gauge threads from leaking air though. It was leaking somewhere behind the gauge and where it threads into the filter body housing itself. Another gripe is that when you thread the gauge into the filter body

I needed a regulator that would work with the pressure my system has. The air gauge only goes to 150 PSI but the description said it was rated for 175 so I gave it a try. It's smaller than I thought but it works well and so far is working with the higher pressure I'm using. I mounted on the side of a work bench so it's very practical and

Sure enough right out of the box the threads were imperfect and had to be re-tapped just as several other reviews state. I got it anyway since this was ''Amazon's choice'' BUT I don't see how. In any case I am keeping it and will update if it starts leaking as others have also stated. I ordered 1/4" ball valves and put them on the

Overall it works fine. The threads on the outlet port were messed up out of box and I had to retap them.... Something you shouldn't have to do for a brand new product, but I guess you get what you pay for.
The inlet and pressure gauge threads were good.
The pressure gauge needle jumps around a little but is accurate.

Overall, this filter seems well designed, is easy to set up and use, and pulls out a lot of moisture. However, as other reviewers have said, if your application is very moisture sensitive, consider a secondary filter somewhere down the line or at your tool. Another tip is to install this filter a good distance away from the compressor

Nice little water trap, just be sure you have several feet of hose between your compressor and they filter. 25-30 ft is best. You have to give the air time to cool and thus the water vapor condense so it can be removed. I have this 90 ft from my compressor and after a 3 stage filter from the same company. It’s sole purpose is to act

Working well. Didn’t realize it came in a kit with other things with it. I’ve never seen plastic quick connect air fittings in this size. I have four different size/style of quick connects but this one is different than all of those and won’t work with any other ones.

This regulator failed explosively in less than 30 days. It seriously shot the bowl off the bottom of the regulator.
