Hi,

I have a Sweetwater aq101 rocking piston compressor. Last year I installed a pressure gauge coming right out of the compressor (9” of line in between compressor and gauge). When I turned the compressor on the needle would rapidly oscillate between two values. I assumed this might be because of “how rocking pistons work”. This spring I went to turn the compressor on and the gauge was jammed. Opening up the gauge I found that the gear on the needle was completely worn out. I assume this is from several months of oscillating back and forth.

Any suggestions on how I might better set up a new gauge so that this doesn’t happen again?

Thanks in advance.

Ted
