Leak from fitting where Ozone injects

[hightechburrito]

The tubing between my Ozonator and the injector fitting sprung a bunch of leaks (hose was brittle and had a bunch of pinhole leaks). Attached picture shows my temporary fix (kinked the tube and zip-tied it). I'm sure the kink will eventually leak so I need to fix this long term.

I'm debating not even re-connecting the Ozonator for a few reasons:

1. It's several years old, so the module may not even produce ozone anymore.
2. Ozonator isn't on a circulation pump, so it only run a few hours a day.
3. Ozone/Chlorine interact with each other so a bit of a waste.

I know I can order fresh tubing and a barb fitting plug to fix this, but there's also a very slow leak where the tubing goes onto the barb fitting where I circled in red. It's slow enough now that it evaporates before forming enough water to drip, but I'm sure it will get worse over time.

Ideally I'd be able to unscrew the barb fitting (above the red circle) and replace the barb fitting with a cap or plug so there's no tubing to get brittle over time and fail. But I'm not having any luck finding the right part online (maybe it doesn't exist).

Anyone else deal with a leak here? Did they do anything but replace the tubing and keep an eye on it for later?

If it helps, I have a Master Spa Clarity 8 from 2021.

Thanks

A short piece of 1/2" pvc will fill the gap nicely. I bevel the edge a bit for easy install. Re-use the spring clamps.
