Frequently Asked Questions
Q: What is the ML B143 cylinder cap and what does it do?
A: The ML B143 is an OEM hydraulic cylinder end cap engineered for the ML55 manual pallet jack hydraulic system. The cap seals the cylinder bore, contains hydraulic fluid under pressure, and provides a mounting interface for seal components. Manufactured from carbon steel with corrosion-resistant coating, it withstands operating pressures up to 3000 PSI.
Q: Which pallet jacks use the ML B143 cylinder cap?
A: The ML B143 is compatible with Mighty Lift manual pallet jacks, model ML55. The cap is precision machined to interface directly with the ML55 hydraulic unit bore. Verify that your jack uses the ML55 hydraulic assembly before ordering to ensure fitment.
Q: What material is the ML B143 and what pressure can it handle?
A: The ML B143 is manufactured from carbon steel, precision machined for hydraulic applications. It is engineered to withstand operating pressures up to 3000 PSI, the standard pressure range for ML55 series manual pallet jack hydraulic systems. The corrosion-resistant coating protects the steel surface from oxidation and extends service life in warehouse and dock environments.
Q: What seals are compatible with the ML B143 cylinder cap?
A: The ML B143 cylinder cap interfaces directly with the ML B142 o-ring and ML B141 U-Cup hydraulic seals. These three components work together as part of the complete ML55 hydraulic assembly. Both seals must be present and properly seated in the cap to maintain pressure containment and prevent fluid leakage.
Q: What are the manufacturer and OEM part numbers for the ML B143?
A: The manufacturer part number is ML B143. The OEM part number is also ML B143. This designation matches the Mighty Lift specification for the ML55 hydraulic cylinder end cap. No alternative cross-reference part numbers are available. Use this part number to order the correct cap for your system.
