This product is similar to the Moose Valve and the Beck Valve but was designed specifically to fit in McCallum blowpipes.
Easy to install in the blowpipe of any McCallum brand bagpipes. This works as a 1-Way valve, as well as a spit trap, preventing any spit from getting into the bag.
This can be used along with a Flapper Valve, but not a Lil Mac Valve as the 2 will interfere.
