Josef Klier Mouthpiece Adapters

Don't let the awkward description from the manufacturer fool you - this is an excellent adapter for using a tuba mouthpiece with the smaller 'American'-tapered shank in an instrument with the larger 'European'-sized receiver. The adapter will also insert almost exactly one inch into an American-sized receiver. So if you own such an instrument, this adapter can be used to bring the mouthpiece rim further from the body of the tuba for improved ergonomics.
