Conn 20K Sousaphone Valve Stem Standoff

The idea for this part came from Master technician John Blythe.  This part replaces the E-clip that is used on the valve stem under the felt.  The E-clips tend to fail after a time.  Our standoff will not.

John originally made a few of these himself, but soon came to realize that we could make them more affordably and of a real high and consistent quality-so he asked us to build them.
