Quality, easy to use, and works! ๐
John Guest fittings have a lot of positive reviews and customers said they are good quality. So far I have no reason to say they are not quality. Every John Guest fittings I have used so far has been leak free and just works. I do recommend these fittings over other questionable brands. John Guest Speedfit 1/4 Inch... https://www.amazon.com/dp/B005S4NYI8?ref=ppx_pop_mob_ap_share JOHN GUEST 1/4" One Way Check... https://www.amazon.com/dp/B00AELC3MI?ref=ppx_pop_mob_ap_share AO Smith Under Sink Water Filter... https://www.amazon.com/dp/B07NJ4P99G?ref=ppx_pop_mob_ap_share AO Smith filter was purchased after I read many positive reviews. I've been using it for about a month and so far it has been great with no leaks. I am looking forward to the savings I'll have because of the life and cost of these filters. Straight Stop Valve, SUNGATOR... https://www.amazon.com/dp/B0CLY7K4LK?ref=ppx_pop_mob_ap_share Valve works great! 1 day after I received it I had a leak at a old tap made in my copper pipe mostly because I touched it after I added my water filter and I believe the seals inside were very old. So I cut the horrible mess of plumbing and added this valve inline and am happy to say no leaks and hopefully my copper pipes will be better with this setup and have a long leak free future. J John Guest 1/4 Inch x 25 Feet... https://www.amazon.com/dp/B00N4O434I?ref=ppx_pop_mob_ap_share The John Guest brand has a lot of positive reviews and customers said they are good quality. So far I have no reason to say they are not quality. This tubing looks nice and appears to be of quality material and works well for my needs for my refrigerator supply line. SUNGATOR End Cap, 1/2-Inch Push... https://www.amazon.com/dp/B082KXR42G?ref=ppx_pop_mob_ap_share I have confidence with these caps from my experience with the Sungator Straight Stop Valve. I purchased these in case of a emergency and if I need to temporarily cap a line before I can do a repair.

High quality
I feel like these were really expensive but they do a great job. Used with a variety of OD lines/materials and it grabbed on to all of them with no leaks. Release seems to work pretty good to.

Quality and not flimsy. Leak free with no adjustment needed
The high quality I have seen hands down. Iโve never heard of JG (John Guest) until I had to replace my RO storage tank. I used to add a second storage tank for capacity while replacing the defective unit. Looking at the RO system other fitting are also on system like another tee like this one following shut offs, hose also the same manufacturer. System has been leak free and nice we when needing to remove hose from couplings. Removes like that are brand new. If installing or retrofit I would recommend this brand.

Can be expensive and hard to find in Canada, but work great.
Love the many different options for these connectors. I needed a T to run a new water line to a steam oven. Existing lines were 1/4" and that line needed to be 3/8". You need to make a good flat clean cut and ensure the line is fully seated to avoid leaks, but this works well. When I needed to shorten the water line after the oven was installed to take up slack, I was able to disconnect the line, cut it to the better length, and then reinsert it.
