I measured aprox 7/16" diameter for the female thread diameter, and ordered a fitting for that measurement from a different brand, and it turned out to be too small and costly. I saw this brand YZMSZ at much better price and ordered a 1/2" fitting since the 7/16" from the other brand was was too small. I received it and it was way too big, and I noticed this was a common theme from reviews here and elsewhere. I almost ordered a 3/8" thread size, but then I noticed the mm measurement on the chart provided by the seller pictured above for the male inner diameter and the female inner diameter. The 7/16" measured female threaded fitting I have is attached to a 1/4" tube which I believe is where the 1/4" description comes from (the other end for the quick connect is also 1/4"). It's confusing, and I have no idea what the costly first brand I chose used for sizing, but it doubly added to my confusion. When I received the 1/4" female threading size from YZMSZ, I finally received the correct size.I was also concerned that these fittings wouldn't come with a gasket since no gasket was listed in the description, but I remembered that the 1/2" came with a gasket. However, the 1/4" did come with gaskets. I used plumbers tape on the thread and hand tightened only as tight as I could with the gasket in place inside the female threading, and voila! The fittings worked perfectly with no leaks for the 2 cracked fittings I needed to replace.Pictures attached to this review include the female thread diameter in centimeters (millimeters), also measured in inches, the gaskets for the fittings, and the new fittings installed.

Product looks fine, but did not get chance to use it because I ordered 3/8", it says 3/8" on the packet, but the contents are 5/8" so returning.

I use these to adapt 1/4 line to a 1/2 inlet on water bowls. they work fine for what they are, and come with a seal in the bag. durable enough to not leak.

It works as expected, with no leaks. To ensure you have no leaks you should cut a fresh square end on your hose and press it in firmly. If your cut is angled you are likely to have a leak.

I have them on a 25 watt UV Sterilizer off a RO water filter. UV gets hot. These fit and seem to be well made, should hold up to the heat. It's also nice that I can see that the UV light is on through these fittings.
