Our Dynabrade air random orbital sander seems to be going through connectors fairly regularly. The male and female ends get locked together. We're only using it for a couple of hours a day. Is this normal? Would a better brand of connectors work better? Right now, we're using cheapo ones from Northern Tool.
From contributor M:
Are they left connected all the time? During heavy operation a lot of condensation can build on the coupling. If you are not already using a good air drier and oiler, try that first. Beyond that, popping the connector loose and cleaning it would probably fix the issue.
