These weights add 50 grams of mass to the valve cluster, resulting in a more focused and denser sound. They are particularly effective on yellow brass Geyer-style horns because the instruments themselves are so light.  They screw onto the top of the casing and the cap is screwed on the top. Valve casing weights are usually used on the 3rd valve.

*The 4th valve weight for the Texas Conn 8D will also work on Elkhart era Conn 8Ds.

Made in the USA.
