A hydraulic fitting is used to fluidly connect hydraulic hoses on opposite sides of a bulkhead of a machine. The compartments respectively receive hard disks, the supporting bases support the hard disks and secure with the hard disks to prevent the hard disks from moving along a first direction; Each latching member engages with the opposite receiving grooves, separate adjacent hard disks, and prevent hard disk from sliding along a second direction perpendicular with the first direction. The moisture sump allows condensate management of difficult to drain areas such as the inlet to the expiratory check valve of a ventilator system.
