Nomad 2 fail

If you are unable to find a leak at fault the water-less, oil-less disposable compressors are only made to last about 20 hours. So, if you are near or at the end of life for the unit it will need to be replaced. At the very least it will need a complete rebuild rebuild including the piston o-rings and any gaskets involved. The glorified electric hand pump compressors do a bit better but still need their piston o-rings replaced fairly often.
