Harbor Freight Tools that did not make it. Harbor Freight Tools that have made the grade.I broke my first Harbor Freight tool this year - a 12 year old soft-headed hammer. I was abusing it.
That makes it 1:100(or more) failure:purchase ratio. Don't buy the cheap looking tools from Harbor Freight and you'll be OK.
I had a leaking HF water separator and it was as Stuart and others suggested. The gasket/seal/o-ring had slipped out of place. It works fine now.

PS: Since 80% or more tools come from China, let's not simply blame the country of origin. Sometimes you get what you pay for; sometimes you're simply paying for a brand name; sometimes a good brand name has been earned on a record of quality (and is worth a higher price).
