Can anyone tell me if the object in these pictures is a standard item
available in hardware stores and what it is called?
It is a circle of rubber 1 1/16 inches in diameter, 1/16 inch thick, with a
slit in the center 1/8 inch long . It is used as a pressure release valve in
I am wondering if I can buy these at home depot or somewhere like that, and
I'd like to know what they are called, what department to look in etc in
case the person I ask in the store doesn't know.
Otherwise, does anyone know where I can buy a sheet of rubber 1/16 inch
