Coilhose Pneumatics 4214 ADJ Adjustable Regulator Review

This regulator is a game changer for compressed air treatment in the industrial and scientific sector. Thanks to my knowledge gained in practice, I was able to easily adjust the settings to my requirements. The adjustable pressure range helped me to fine-tune the air supply and thus achieving better results in my work. The build quality is top-notch and ensures long-term reliability. However, the price may be a bit steep for some. Overall, highly recommended for any serious professional LOOKING

From what I understand it's brass, so it's a soft material. However, after several adjustments trying to set the pressure, the screw stripped the brass threads. You should get the correct torque as there is another vent on the opposite screw size under the black cover. How tight you tighten the screw can affect the pressure in the regulator block. Like I said, it's very picky. I would recommend either buying a solid pressure model or looking for something else.
