I like professional as well when it is available in the right size.

The clamp yous how would be too small I think. Maybe not. I have both the plastic clamps from Jehmco and the stainless steel hose clamps that are screwed to tighten or loosen. I use these clamps on all my disttibution airlines but not the final airline hose. I use assoreted size clamps on all canisters and inline heater connections. If these hoses go you can drain a tank onto the floor. But these clamps do not fit the airline, they are too big.
The nice thing about the wire ties that are they are cheap, that they can fix a huge variable if sizes, that they should not be toxic and that the are easy to hide.
One oft the problems I encounter when connecting airline to valves or manifolds outputs is being able to slide them ell onto the barb. The fir is often tight. But I have solutions for that as well so I can attach them securely. One is to run hot water over the end if the airline to softn it. But if that doesn;t do the tricj I use a scissors. I insert the tip (closed) into the airline and then open the scissors some. This cause a bit of a flare in the end ot the airline which lets it slip on t=initially with ease. Then pushing in a ways becomes a lot easier.
At my peaks I had about 26 manifold connections plus a few more small airpumps on tanks not in rooms with central air of any kind. As long as I get the initial connection on solidly I get almost 0 disconnects. Most air bars and discs are crappy and they seem almost designed to not stay attached well to the airline. I have almost never had to use the wire tie trick on air powered things.
Also, who cares how it looks as it is not visuinle when burried? All that matters is does it work. Plus they are a fuel line clamp and may squeeze a bit too hard? If you want the SS clamp get the right size diameter. My wire ties fit a lot of sizes with the same tie
And they can be used on more than one application.
I think either solution will work though.
