Product Description
The ML A325 is a polyurethane U-Cup hydraulic rod seal designed for manual pallet jack pump systems. This direct replacement seal prevents hydraulic fluid leakage under dynamic operation in pump cylinder assemblies and maintains system pressure during use.
Engineered for Mighty Lift ML55 and ML55L models, the ML A325 delivers reliable sealing performance across reciprocating motion cycles. The thermoplastic elastomer construction resists wear and remains compatible with standard hydraulic oils ISO 32-46.

Frequently Asked Questions
Q: What is the ML A325 seal and what does it do?
A: The ML A325 is a polyurethane U-Cup hydraulic rod seal designed for manual pallet jack pump systems. It prevents hydraulic fluid leakage under dynamic operation in the pump cylinder assembly.
Q: Which pallet jacks are compatible with the ML A325 seal?
A: The ML A325 fits Mighty Lift ML55 and ML55L manual pallet jack models. This includes alternate model designations ML55-II, ML55II, and ML55 II with matching L variants.
Q: What material is the ML A325 seal made from?
A: The ML A325 is manufactured from polyurethane, a thermoplastic elastomer engineered for hydraulic sealing applications. This material resists wear and maintains dynamic sealing performance.
Q: What hydraulic fluids are compatible with the ML A325?
A: The ML A325 is compatible with hydraulic oil ISO 32-46 grade, the standard for manual pallet jack pump systems. Verify the pump specifications before selection.
Q: Can the ML A325 be used for both OEM and aftermarket repairs?
A: Yes. The ML A325 is designed as a direct replacement for both original equipment manufacturer repairs and aftermarket maintenance applications on Mighty Lift ML55 series pumps.
Q: When should the ML A325 seal be replaced?
A: Replace the ML A325 if you observe hydraulic fluid leakage around the pump rod, loss of pump pressure, or visible seal degradation. Standard replacement intervals depend on operational hours and fluid condition.
