how to add feed for reverse osmosis

[StrategicReef]

I have regular shut off valve under the kitchen sink I was wondering how I could add the RODI to it.

I see there is some adapters available to install either on the faucet or shut off valve side but I don't know which to get. I think the shutoff valve has 3/8" compression output.

I don't want to use the pierce valve or replace the shutoff at this point..


Maybe something like

but are these available without ordering online?

Is this the same thing from home depot?

Funny, I had to use the T-adapter today. The bonehead plumber didn't leave me enough room to use the TAP adapter.

I used the tee adapter and a 1/4 compression nut w/Insert part#17000004. I had to cut the flared insert to about 3/8 inch. It originally was way too long for the nut to reach the 1/4 thread of the tee adapter.

It was a pain to cut the little brass insert. I place a large nail inside the insert and cut around the nail. I was scared i was going to bend the brass and have to buy another one.

Worked perfectly.

Welcome to the joy of plumbing! Now you know why the plumbers' trucks have a thousand little bins with different connectors and adapters in them!

An adapter like you linked to should work, but it depends on what size fittings you have. Check the size of the faucet supply line, or shut off the supply and take the whole thing with you to the hardware store, along with the adaptor you have for your RO/DI setup.

Home Depot and Lowes carry 1/4" murlock fittings, similar to these], so you might be able to find something like it there.

Your doing something wrong or the parts was not right for the application? You shouldn't have to cut anything. The Photo below part will work every time. (Don't use any brass sleeve on plastic line)

I use this and it works great. Just get a valve to go with it to shut on and off flow to the RO unit.

The least amount of connections the better, my choice was a dual outlet you have full control of ether outlets for any emergency shutoff.

I am confused by your response. You say not to use the brass sleeve on any plastic line. Your picture on the part to get has a brass sleeve and your next post is a brass valve???

Are you saying to only use the plastic compression sleeve?

I know that using a brass anything on RO water specifically will eventually deteriate the brass, but this is the main input.

In case anyone is interested, this is the RIGHT part for the job.

Yes, "not to use the brass sleeve on any plastic line". "picture on the part to get has a brass sleeve" it did not show a brass sleeve, fact is you did not see the sleeve is not brass but a 'Delrin' sleeve (plastic) and the insert, is brass.
'Sleeves' AKA ferrules, would be the part that makes the compreshion around the tubing and the insert is what keeps the tubing from collapsing in under compreshion on plastic line only as I'm sure you know. Brass sleeves AKA ferrules can and often cut into the plastic line especially if the line is wiggled a lot (lets say you installed a inline valve and the line is often moved) The part in my post is used for plastic line and is correct.
