Secbolt Pressure Switch Manifold Regulator Gauges Air Compressor Pressure Switch Control Valve 90-120PSI (American Pattern)

Fittings good quality, and kit makes it adjustable so you can arrange it to best suit you needs! Got mine installed and runs like a fine oiled machine!

I give this item 5 stars because it does everything promised. The manifold is pretty sturdy despite it's appearance and feel. I do think the manifold could be improved and if it was, I would pay more for the product, but the manifold supplied went on well and is holding up fine for me. The directions are not very good. I used the directions and the pictures on Amazon to help me. Plan ahead. I lightly threaded everything together and practiced the sequence of how I planned to assemble this onto my compressor before I started the final assembly. Once you break out the thread locker you are committed so be sure of your assembly sequence a head of time. I found the thread locker to be easy to work with and there is plenty there for the assembly. I used the thread locker liberally and found that it gave me cover to not over tighten the fittings. I tightened everything up and got it straight with out the need to give the fittings that "one last turn" and then over tightening the fitting. I let the tread locker sit for 4 hours before I pressurized my compressor and had no leaks(I think this was due to the thread locker filling in the threads very well). I did have a couple of old 1/4" plumbing parts so I tested the thread locker on them ahead of time. I found that the thread locker is great at preventing leaks and tough to disassemble. I would buy this product again.

Scored a small 8 gallon air compressor at a yard sale. Unfortunately, its mode of operation was pressurize to the max the safety valve was set at, then it trips, dropping to around 60#. System never shuts off and if you are using tool that required pressure above 60#, it’s useless. I found this unit and thought, perfect to retrofit this bargain. Installation was pretty simple until I tried to install the 1/4” copper pressure feed line from the switch to the newly added tank fitting. The problem - the ferrule on the pressure switch will not fit standard 1/4” copper line. My solution was to replace the ferrule and the nut with parts from a store bought copper line fitting. Fortunately the threads on the new fitting matched and no leaks.I fired up the unit and the switch tripped at 125 psi (a good thing) just as the relief valve started to trip (a bad thing). Thus the second issue - relief valve stayed leaking until it hit 60#. Since my original safety valve was set higher (yes, the original manufacturer’s valve was set higher as system was rated for 135 psi), I swapped relief valves. Now there are two adjustment screws on the top of the valve to (I assume) one lowers the pressure trip point on the pressure switch but the instructions that came with the unit do not define which one. Looking at the mechanics, I’m pretty sure which one it is but CW or CCW is the question. Bottom line - I like the unit and it does exactly what I want it to do but it will take some mods to interface.

I replaced my check valve and that fixed my problem of the pistons filling up with air and the pump unable to keep pressure unless I drained the air out and restarted the compressor. I did not return this part since I had it. It works good. The levers are fragile plastic, but for the price, I’m ok with that. An easy instal, I replaced the copper line, because it bent during removal more that I liked. Just a preventive move.

I am disappointed with this product. My old compressor had a failed pressure control valve and a bad pressure gauge. I thought this product would suit my needs. I was wrong.The pressure switch control valve works as expected. However, the air pressure relief valve trips before the tank reaches 120 psi. This forces the compressor to run continuously because it can't reach the shutoff pressure of 120 psi. In my case, I was able to reuse the old pressure relief valve from my air compressor.The "extra spare parts" that are part of the package are of little to no use. The provided shutoff valves have such a small opening that they restrict air flow too much. The two provided quick connect couplers are non-standard and not usable.The gauges work fine.If I were to start over, I would choose a pressure control valve and a single air pressure gauge to replace the defective parts on my air compressor and not get the extra pieces in this package.

Actually good quality and fitted nicely. Gauges are nice quality too.

Direct replacement for the switch on my 40 year old Italian compressor. Will this one last as long? :)

Sería bueno que incluya un instructivo de instalación

Assez facile d`instalation. Manquait un joint ( gasket ) ou ( o ring ) a l`entrée de la bonbonne.

The setup does not hold pressure
