Trum-Cor makes practice mutes for 4/4 and 6/4 tubas. They are based in the Dallas area. Their 4/4 practice mute works very well on my Hirsbrunner. The resistance is noticable, but tolerable, and the pitch stays well enough in line. I don't have their info on hand, but I'm sure somebody on the BBS does.
Happy practicing.
