Michael Rath heavy valve caps are designed for use with Rath Custom Series trombones fitted with Hagmann valves.

Replacing the regular weight valve caps, our heavy caps add stability, core and particularly projection to the entire range of the instrument, without sacrificing flexibility.

Importantly, testing has shown that our heavy weight valve caps give equally good performance with any trombone using a Hagmann valve, in some cases dramatically improving the playing characteristics.

The Michael Rath heavy valve caps do not require any prior adjustment to the valve or instrument.

Note: This is the correct size for the new type valve which came out late 2016.
