Frequently Asked Questions
Q: What is the ML B119 screw plug used for in Mighty Lift ML55 pallet jacks?
A: The ML B119 is a threaded access plug with copper washer sealing interface located adjacent to the damping valve in the ML55 hydraulic unit. It provides service access for maintenance and fluid containment.
Q: What equipment does the ML B119 fit?
A: The ML B119 is designed exclusively for Mighty Lift ML55 series hydraulic pump units and the ML55 manual pallet jack hydraulic assembly.
Q: What are the cross-reference part numbers for the ML B119?
A: The ML B119 can be referenced as MLB119 or B119 in generic Mighty Lift documentation. All three designations refer to the same OEM screw plug component.
Q: Why does the ML B119 have a copper washer?
A: The copper washer creates a reliable seal at the threaded plug interface. Copper resists corrosion from hydraulic fluid and provides superior sealing performance compared to standard steel washers, preventing leaks at the damping valve access point.
Q: When should the ML B119 screw plug be replaced?
A: Replace the ML B119 if you observe hydraulic fluid leaking from the plug area, if the plug threads are stripped, or if the copper washer is visibly damaged or compressed. A leaking plug indicates loss of hydraulic fluid and potential system failure.
