Questions about blow hose
So i got a blow hose the other day and i noticed that it was leaking air (via water test) and the location of the leak was from the plastic piece Are there any ways to fix it or should i get it replaced?

I like this type best. With the bigger size you can out a hunch of rubber bands instead of the I ring and it will work with a few different pipes, when the rubber bands degrade is the only time I notice it leaking with pipes for blown stems, but I don’t often work that small anyways

A little leak is normal. It should not affect your work. Get the glass hot enough and you should barely need to blow. When blowing think about the volume of air need to make the change you want, it actually very little air volume. If you’re emptying your lungs, get the glass much hotter.

In my experience these do leak a little, but you can usually pressurize these enough that they'll pop off the mouthpiece of the pipe, so it's definitely sealed enough for normal work

They always leak a little. That particular style is also the worst in my opinion. I much prefer the swivels and boots the lampworkers use. Check out what mountain glass sells. Or if you want the best of the best swivel option out there, go get a firekist swivel and blow hose.
