Review on 💧 Water Purifier Filters' YZM Tube Quick Connector Fittings for Reverse Osmosis Systems - Set of 5 (Straight, 1/2" Male x 3/8" OD Tube) - Accessories by Steven Ross

The version I received did not have the blue clips shown in the product photos. Also, I tried 3 out of 5 and they all filtered through like a sieve. I went to a major hardware store and bought the same John Guest brand fitting (at a much higher price) and an alternative, no leaks. Same teflon tape. There may be multiple versions of this suggestion, but I would recommend saving yourself the hassle and purchasing a higher quality product. Compared to the John Guest product, the threads on the John Guest are significantly sharper/longer. I wish it would work, it's by far the best value for money, but if 3/5 is leaking and you spend hours taking things apart, repackaging and trying different fittings, a little more money might be worthwhile for one better quality part. If you request a refund, we'll see what happens.
