So close but so far wrote

I made a hefty investment in these, believing them to be the best ever made. After fighting them for a few years now I can report that they simply won’t come apart by hand, they’ll barely come apart with tools, even when greased. I’ve tried several oils and Super Lube synthetic grease. Once inserted, the male side will not come out unless I remove the whole assembly, chuck the female side in a vise, and use both hands on a wrench to twist & pull the male side. Often this destroys the O-ring. The only O-rings I’ve used are the ones AMLeo sells for these fittings - so that isn’t the problem.

Outstanding quick couplers! wrote

These are beautiful, high-flow couplers. This is my first year with them but the in-your-hand quality suggests they'll last many years. I'm writing this after bumping into some of my old "high quality" couplers in the garage this past weekend. Now that I'm used to the AM Leonard couplers the old ones made me laugh: at the flow restriction that made me toss them in a junk box. (They're now destined for metal recycling.) I frequently complain about the quality of products available these days but AML's couplers are top shelf.
