ML B130

Frequently Asked Questions

Q: What is the ML B130 O-ring and where does it seal in an ML55 jack?
A: The ML B130 is a manufacturer-grade hydraulic O-ring designed for OEM seal fitment in Mighty Lift ML55 pallet jack hydraulic units. It seals connections within the hydraulic assembly to prevent fluid leakage and maintain system pressure during lifting cycles.

Q: What material is the ML B130 made from and what temperatures does it handle?
A: The ML B130 is molded from high-performance hydraulic-grade elastomer engineered for high-pressure, low-temperature manual hydraulic systems. It remains flexible and maintains a seal in cold storage environments and winter conditions where standard seals may fail.

Q: Is the ML B130 included in any seal kits?
A: Yes, the ML B130 is included in the B-Series Seal Kit for Mighty Lift ML55 hydraulic units. If you are performing a full seal kit replacement, the ML B130 is one of the seals included in that kit.

Q: What are signs that the ML B130 O-ring has failed?
A: A failed ML B130 causes visible oil leaks from the hydraulic unit, loss of lifting pressure, or inability to maintain load after the jack is lifted. If your ML55 leaks fluid or will not hold pressure, a degraded seal kit including the ML B130 may be the cause.

Q: Are there alternate part numbers or brands that are equivalent to the ML B130?
A: The ML B130 is identified by alternate references as MLB130 and Mighty Lift B130, but these all refer to the same OEM component. No known interchange parts from other manufacturers are listed. Order by ML B130 to ensure correct fit and material specification.
