Parts for different incarnations of the Badger Renegade Khrome series are not interchangeable. That's why I have an earlier and later version.
Ok but just double check your owners book for the part number you need, according to Badger's website the part # for the air valve is RK-0021 for the complete air valve assembly, also that is the part number in my book for my several years old Krome, I got mine on August 23, 2012. and the air valve sold on amazon is RK-0021.
P.S. this is no a flame war, I just don't think getting a replacement part is that difficult.
