A simple and essential tool for any brass instrument repair technician. The Leak Check Bell Plug creates an airtight seal in the bell of the instrument allowing you to pressurize the entire horn and check for leaks throughout the body, slides, and braces — not just the valves.
Simply insert the plug into the bell, tighten the wing nut to expand the rubber seal, and pressurize the instrument. When finished loosen the wing nut and remove. No tools required.
Available for:
Trumpet
Tenor Trombone
Bass Trombone
French Horn
Used by professional repair technicians worldwide. Ships internationally.
