Frequently Asked Questions
Q: What is the ML B120 Copper Washer used for in ML55 pallet jacks?
A: The ML B120 is a sealing washer component used in ML55 manual pallet jack hydraulic unit assemblies and B-series seal kits. It creates a corrosion-resistant seal at threaded hydraulic connections.
Q: What equipment is the ML B120 Copper Washer compatible with?
A: The ML B120 fits Mighty Lift ML55 series manual pallet jacks, specifically in hydraulic unit assemblies where factory seal kits are applied.
Q: Why is the ML B120 made from copper instead of steel?
A: Copper resists corrosion from hydraulic fluid and provides superior sealing characteristics compared to steel washers. Copper is softer and conforms better to the connection surface, reducing the risk of leaks in high-pressure hydraulic applications.
Q: What are the cross-reference part numbers for the ML B120?
A: The ML B120 can be referenced as MLB120, Mighty Lift B120, or B120. All three designations identify the same OEM copper washer component.
Q: When should the ML B120 Copper Washer be replaced?
A: Replace the ML B120 if hydraulic fluid leaks from the sealed connection point, if the washer is crushed or permanently deformed, or if visible corrosion or pitting is present. Damaged washers cannot maintain a reliable seal.
Q: Is the ML B120 Copper Washer included in Mighty Lift B-series seal kits?
A: Yes. The ML B120 is supplied as a standard component in Mighty Lift B-series seal kits for ML55 hydraulic unit maintenance and overhaul.
