Thought Id share this little project. I have a couple tight turns in my brewing setup, that when I'm running hot wort through the lines they can collapse if I'm not careful.
I bought these Stainless springs
from McMaster Carr, they fit nicely over 1/2" ID silicone hose and can be cut to length. As an added bonus the spring can be wound around the blade of a worm clamp to protect the brewer from the sharp blade.
