2110025-1 and -2. These are the ones on the wing root rib that allow fresh air in but have the butterfly valve inside that closes and allows the aircraft to pressurize.

Does anyone have a solution to the old, dry, brittle fresh air valve boxes on the P210? Does anyone know of a company out there that has a PMA'd version of these fresh air boxes or a solution to replace or repair them?
