The edges of sharp and/or soldered tone holes can damage the O-rings on a Schmidt Leak Isolator.
If an O-ring gets damaged it’s important to replace it promptly. Lubricate the O-rings by applying a small amount of Magic Dust.
The smaller O-ring is an option when the flute bore is a little smaller and tighter than normal.
