OK, the parts in the picture are from my Insta-Hot. It’s actually a “Franke, Little Butler”. When you call the customer service number listed on the tank, you’re calling “Anaheim mfg”, who sells no service parts. The plastic “nut” is 1/2″ flare thread. It slides over the copper 1/4″ supply tube, pinching the silicone barrel and creating a seal. The supply tube is not under pressure until you move the handle on the counter mounted dispenser, forcing water into the tank. A regular 1/2″ flare nut is tapered for the 1/2″ flared tubing. I’m afraid it wont seal tight enough. Someone suggested a 1/2″ X 1/4″ flare reducing, but haven’t been able to come up with one. I’m again concerned about the flare in the nut not compressing the silicone barrel enough. The plastic nut has a flat top. Any suggestions will be appreciated. Sorry the picture isn’t crisper.

What connection is this? The on in the back right corner or the one in the center.
The one in the corner is the cold water from the valve and uses a copper tube. On my older unit they there is a small 1/4 stub out and uses a common 1/4" compression fitting. Looking at the current installation manual it is still the same, but it they use a plastic push on connector similar to a sharkbite.

The one in the center is the vent and hot discharge. It uses a common vinyl tubing. And a spring clip that connects it to the stubout. I think that it is 3/8.
It looks like they use the same method.
But this ad makes it look like they have somekind of quick disconnect fitting.

Now this is the instructions for the Franke.

And it looks like what is shown in the ad is not a quick disconnect but some kind of adapter. The don't show how the copper tube is connected.
If it is the center on they show a part number, FR9100, under spare parts.
And they give this phone number in PA 215-822-6590
And on the main website they have an 800 number.

"I have the same unit and had a similar problem. If yours is the same as mine, look at the top of the water heater unit. The center spigot is for the for the how water outflow which is connected to surgical type rubber tubing. The hot water eventually dried out the tubing and it cracks, causing it to leak. I had to cut out the decayed portion and replace it. Franke sent me a replacement kit at no charge but I did replace the fitting on top of the unit. The fitting is a standard nipple that any HW store should carry. Mine is a female-to-female reducer that then mates to a nylon barbed fitting which the tubing goes into. Importantly the Franke supplied kit has nylon ratcheting hose clamps that keep the tubing in place as well as a barbed union with hose clamps to join to the exisiting hose feed (to the faucet).
Hope this helps! I'm now struggling with the hot water tap leaking after using it. It seems to stop after a while but it drips for some time. If you can help me there that would be great!"

Hey Bill, This fitting is "inside" the unit, you know, one of those places you're not suppose to enter. If you use this link, http://www.anaheimmfg.com/products/hotwater/quick_hot.html, Look at the fitting at the end of the arrow pointing to
IMPROVED PERFORMANCE. That's the little bugger!!We've had two failures of the surgical tubing at clients homes. I'm familiar with that scenario.Thanks for the reply,HV
That looks like a it is connected to the tubing with a spring clip.I would think that you could replace it with some standard hardware store parts. A barb fitting, with threads on the other end and then a 1/4" compression fitting..

Bill,It's not a spring clip. The end of the " copper tubing is flared, and the silicone barrel slips over the tubing, acting like a compression furrel. The nut squeezes/compresses the silicone and tube down inside the 1/2" male end.On your dispenser, is it leaking up inside where all the tubing connects to the valve or just dribbling into the sink from the aerator end?Harry
What I posted in the other message was what I found in another forum.My unit is the Quick & Hot. I think that the only difference are the valves.A couple of years ago the plastic tubing had gotten brittle and I replaced it. Was able to take the faucet apart to change the connection at that end..
