Issue with pressure at attachment - restricted flow for some time

by Nathan
(Harrisburg, PA)

I have a craftsman oiless air compressor.

All tools that I attach have low pressure to start. After I hold the attachment wide open for about 10 seconds, it will eventually break loose and the air flows normally.

Once I let off the attachment and try to use again, it does the same thing.

It seems like it could be a valve or something.

Example: I have an attachment for pumping tires that has a handle. I have my compressor set at 80 psi but when I initially hold the handle it is only blowing maybe 5 psi. After holding the handle for about 10 seconds, it "breaks loose" and the air flows freely at 80 psi. I need to have the compressor set at 65 psi or more or it will not even "break loose". What is going on here?

Nathan, I suspect you may have a mis-matched coupler/connector or the checked coupler has a problem.

Have a look at the COUPLER & CONNECTOR pages if you want more info about how they work.
