Jupiter Sousaphone / Tuba Valve Springs Set of 3

I bought these for a marching tuba I have that came with weak springs. With these, the valves respond flawlessly.

These springs are great. Just what I needed for my Jupiter sousaphone, although I'm sure it would be able to fit into any other tuba/sousaphone valve. I keep an extra set in my bag. They're very well-made and large, so you can be assured that the spring will bounce back up nicely when you push on the buttons of the tuba. There's not much else to say other than I'm very satisfied.Bottom line: if you need new springs for your tuba, you can't go wrong with these.

The valves don’t get pushed back up on time. The springs lack in pressure and make the sound sloppy.

Upgrade my euphonium springs to stop sticking valves.
