This is an authentic part that is intended to be used with air compressors from Porter Cable, Black & Decker, and Bostitch. This safety valve attaches to the switch box or the manifold, and is used to release air from the tank if the pressure becomes too high inside the tank. If the safety valve goes off it will need to be replaced, because it can not be reused. The safety valve is sold individually.

I followed the repair steps in the video, which was 100% on target - except for one slight omission. Notice in the video, the tech is using long Torx wrenches to remove the three bolts holding the compressor housing together. Without using long wrenches two of the bolts will be impossible to remove.
