I am looking for Y connector that I can turn off the supply to Bedroom and open the living room supply?

For us, this only functions as a splitter that we both use i.e. in bed at night he has a canula, I have a canula from one machine.. You might look for something with a little valve on it?

I'd like to have a manifold to connect to one conentrator that would accomodate three lines, one to the kitchen, one to the bedroom and one to the den

Have you tried a fish tank manifold like this o e here on Amazon? Kangkang@ Stainless Steel Aquarium Fish Tank 3 Ways Manifold Air Pump Splitter Lever Control Switch Valve Taps Aquatic Accessories

Is there some kind of shutoff valve available so I can have a long and a short canula connected at the same time but only have one flowing at a time?

Not that i have found, I looked at and purchased several valves online none were of use. To keep from changing canulas & tanks, here's what I purchased & built. From amazon I purchased: (1 ) uxcell 1/4 PT (2) way air manifold, this has 5 ports. (1) uxcell air 1/4 pipe plug fittings pack of 5. (1) #0007 oxygen supply tubing from westmed.Comes in a Pack of 5. -----' Went to plumbing supply store & purchased ,(1) Teflon tape role, (4) 1/4" PT barbed Hose fittings, (4) oxygen tank wrenches. This way I use the regulator to turn the tanks off & on with out removing them from the bag. Hope this helps, good luck.

Im on high flow oxygen and have 2 concentrators. I need something that will connect the two tubes into one cannula. Would this work?

We (my husband and I) each have a concentrator. We used this connector to join his cannula and mine, thus ending up with one tube we ran upstairs and then used a splitter to separate the one cannula into two again, one for each of us. I believe this should work fine for you.
