Fit my King 3B. Worked well for a year and a half and then it broke. The original spit valve spring broke after a few years so it may just be me.

This is a solid, fairly heavy duty spring. Should last for 15-20 years.

My spring broke during rehearsal and I used a rubber band as a temporary fix. Asking on a trombone forum I found out that many trombones have springs that are specific to their brand. This spring is specific for the king 3B and fits my 3B perfectly. I did the installation myself after watching a couple YouTube videos.
