Moisture from hand pumpsJuly 13 2017 at 8:35 AM

Response to Corrosion in Daystate Regal
Pumping indoors does very little to reduce moisture from hand pumps. You have to get the dew point down to about 0 deg F to be really effective. The moisture can easily corrode any aluminum parts in the tube (valves, gauge blocks, etc.), and that granular corrosion oxide can cut/scratch the o-rings. The lack of effective moisture filters for hand pumps is a real problem. The little harbor freight desiccant filters do almost nothing (the air isn't in the filter long enough to get the moisture out).
