Not only does the quality seem nice, but I truly and 100% appreciate the 3/8-1/4 connectors that came with it!My fridge water dispenser line was cracked when I purchased the refrigerator. The crack was right at the bend where the top of the fridge goes into the door of the dispenser. Very poorly oem water line quality and especially the installation of it.The OEM line was also just shy of 3/8 (thats how they get you!), so typically one would have to run the whole water line through the fridge since it wouldn't fit the standard 1/4 - 3/5 connectors. I was very disappointed that ended up being the case. But my DIYer creativity mind kicked into gear, put a 3:1 heat shrink near the end of the line where I cut the section where the crack was and then bam! The 3/8s end of the connector fit on and was water tight. I really needed that win, especially with the constant bad luck that has been kicked into high gear lately.I did not end up using the 3/8 tube that came with it. Not because I didn't like it, but because I also purchased a 1/4 set with connectors, which didn't come with the 1/4-3/8 adapters. (I found out the 1/4 was too small at first due to misinformation from the fridge support. Long story.).Anyway, I wanted to use the 1/4 tube, because I wanted to have more water pressure come from the dispenser and it works beautifully.I provided a picture of the repair I ended up doing. Hopefully it helps someone out there! ♡

Bought this with the additionsl 25' tubing. Makes for a terrific set to convert my RO output to the refrigerator to 3/8" with all the tubing and fittings you need. The cutter is a nice addition for making square cutoffs. The only downsdide is that the ball valves have obstructions that severely limit the throughput, probably to less than 1/8". A 1/4" drill bit cleaned it out perfectly without creating any problems or leakage.

i needed to splice in a shutoff valve to an existing R/O system, so i pretty much only used one valve, one connector, and the tubing cutter.everything appears to be of great quality, so now i've got spare parts for future repairs!

Obtained this trying to repair Refrigerator Ice maker. Not a job for faint hearted. Finally found the exact parts I needed, fixed leaks and have Ice cubes.

I used this tubing to run a water line from the basement where my water filtration system is upstairs to the kitchen with this tubing. It cut easily, was flexible and easy to fish through the basement ceiling/ground floor. The tubing pushed into the connectors with ease, and I didn't have any leaks. The shut off valve completely stops all the water from flowing through it when the valve is shut off. Overall, very satisfied and I have a great filtered water supply from my kitchen sink.
