Frequently Asked Questions
Q: What is the ML B141 and what does it do in a hydraulic system?
A: The ML B141 is an OEM U-Cup (Y-Ring) hydraulic seal molded from high-durability elastomer. It functions as a piston and rod sealing element in the ML55 series manual pallet jack hydraulic unit. The U-Cup design provides primary sealing on the piston rod and prevents hydraulic fluid from leaking past the moving components during lift and lower cycles.
Q: Which pallet jacks use the ML B141 seal?
A: The ML B141 is designed specifically for Mighty Lift manual pallet jacks, model ML55 hydraulic assembly. Verify that your jack has the ML55 hydraulic unit before ordering. Cross-reference the manufacturer part number on your cylinder cap or hydraulic assembly documentation to confirm compatibility.
Q: What material is the ML B141 made from and how durable is it?
A: The ML B141 is molded from high-durability elastomer engineered for hydraulic sealing applications. This material resists wear from repeated piston and rod movement and maintains its sealing properties under standard hydraulic operating pressures. OEM elastomer compounds used in Mighty Lift seals are formulated to withstand thousands of lift cycles in typical warehouse and dock environments.
Q: What is the manufacturer part number and OEM reference for the ML B141?
A: The manufacturer part number is ML B141. The OEM part number is B141. This designation matches the Mighty Lift specification for the ML55 hydraulic assembly seal cavity, making it the correct reference when ordering replacements or verifying inventory compatibility.
Q: Where exactly does the ML B141 seal install on the ML55 hydraulic cylinder?
A: The ML B141 installs in the seal cavity on the ML55 hydraulic cylinder, positioned to seal the piston rod as it extends and retracts. This location ensures the seal contacts the moving rod surface during all phases of the lift cycle and prevents fluid bypass.
