Bulkhead For RO Tubing?

[sundog101]

I'm needing to find a bulkhead or seal of some kind that could be used for RO or airline tubing. I found these John Guest bulkheads... but it doesn't look like there's an O-ring on the flange side. It needs to be submerged.

Amazon product ASIN B003YKF1SY
Does anyone know of any other ways to have it sealed? I was also looking at a cable gland, but I'm not sure if that would work or not. Thank you!

Its Amazon...super easy to return in case it does not have an o-ring. Listings like these are very deceiving, whether its the image, description, or lack of...

I have purchased these before and they definately do not come with o-rings. You could purchase a gasket sheet from Mernards and probably make a nice seal for one though. You could also purchase a 1/2" bulkhead and a 1/2" to 1/4" threaded adapter to screw a threaded to 1/4" RO adapter into.

@sundog there's your confirmation. Try McMaster-carr they'll most likely have something if you don't want to make your own gaskets.

Will give that a try. Thanks!

Hey, do you have links to these parts or pictures?? Was trying to have an extra RO reservoir line go into my ATO. The storage bin will be place on a metal racking and it’s 27 gallon extra. It will be gravity fed to my 10 gallon ATO with a float valve. The 10 gallon has a tunze ATO.
