Hardline Compression Fitting - Optimus Water Cooling

The best hardline fitting ever made, period. The patent-pending Optimus gasket design is exponentially stronger than any o-ring design ever made. Our 1/8" (3.2mm) thick gasket provides huge surface area to clamp the hard tubing. With ultra-precision machining, extreme corrosion resistant Pro-XE nickel, plasticizer-free

What am I doing wrong? I prep the ID and OD of the 14mm x 10mm tubes then use 14mm compression fittings/o-rings. I've used two different tube brands too. Then I get leaks on multiple fittings. I'm being very meticulous with each. : r/watercooling
