This repair kit contains the precise field-replaceable parts needed to restore proper vent operation: the vent disc assembly ensures the air inlet functions correctly while the bonnet O‑ring restores a pressure-tight bonnet seal. Use manufacturer documentation and exploded views to confirm model and size before ordering.
