I recently purchased a 6 gallon 175 PSI compressor from Harbor Freight. The compressor works correctly, but I can't get the fitting on the hose to index the quick connector fitting on the compressor. I compared the quick connector to another one I have, and it appears that the collar does not have enough travel for the male 1/4" connector to engage it. Has anyone else had this problem, or does anyone have a solution? Thanks.
There are 2 common types of connectors. Unless your female quick disconnect is a universal one, and you will need to get the other type of connector. This is assuming that you are pulling back on the sleeve on the female while pushing the male into the connector. The automotive type has a wide band close to the end of the male and the standard or generic is a taller narrow bump.
