G1/4" Compression Fitting for 3/8" ID, 5/8" OD Soft Tubing, Glorious Black, 4-Pack

i buy some kits of this fittings 3-4 but in this case i'm not happy, thread ring entering in bad position in package and damage firts thread line on fitting thread

Update: I am changing my opinion on these. I do not recommend at all! Not only were they more difficult than normal comp fittings to get on (which is fine, just means its a tight fit), but mainly because the compression rings do not thread properly over the male end of the fitting. Which leaves you with a fittings thats only 25% secure. I have nothing against cheap fittings, but I would stick with barrow for a cheaper fittings over these. A secure fitting is the single most important aspect to a fitting and these lack security that we enthusiasts expect..
