Awesome. That looks great!

I'm assuming that fitting on your cord is making an airtight seal: if so you can add silica to the inside to absorb any trapped humidity. If there are no leaks, you'll stay dry inside and never have to replace it.
Look for "indicating silica". The stuff I use is orange and turns green when it becomes saturated with moisture. Add about an ounce and open it up at the cord after the first few uses to inspect. If the silica stays orange after a few checks, you can seal it back up and not worry about it anymore.
The expansion of the fittings is negligible. These are designed for super-heated steam at pressures of at least 150 psi (or higher depending one the grade of the fittings). If fitted correctly, they should never leak for your light duty application.
Great job. Cheers!
