Frequently Asked Questions
Q: What is the ML B151 seal and what does it do?
A: The ML B151 is a U-Cup hydraulic seal that seals the piston rod inside the hydraulic cylinder. It prevents hydraulic fluid from leaking past the piston while allowing smooth rod movement under pressure up to 3,000 PSI.
Q: Which Mighty Lift models are compatible with the ML B151?
A: The ML B151 is compatible with Mighty Lift ML55 and ML66 manual pallet jack models. It is included in B-series hydraulic seal kits. Always verify your specific model and serial range before ordering.
Q: What material is the ML B151 made from?
A: The ML B151 is manufactured from polyurethane, specifically formulated for piston sealing applications. Polyurethane provides excellent durability and compatibility with hydraulic mineral oils used in manual pallet jacks.
Q: How can I tell if the ML B151 seal needs replacement?
A: Signs of seal failure include visible hydraulic fluid leaks from the cylinder rod, difficulty raising or lowering the load smoothly, or a spongy lever feel. Replace the seal immediately if leakage is observed to prevent further system damage.
Q: Is the ML B151 sold individually or as part of a kit?
A: The ML B151 is available both as an individual seal and as part of Mighty Lift B-series hydraulic seal kits, which typically include additional seals and backup rings for complete hydraulic cylinder maintenance and rebuilding.
