Frequently Asked Questions
Q: What does the MU 21719 hydraulic seal kit contain and what is it designed for?
A: The MU 21719 is an OEM hydraulic seal kit engineered for Multiton S, TM, M, and J series manual pallet jack hydraulic units. The kit contains NBR elastomer seals designed to restore system integrity and prevent fluid leakage in hydraulic cylinders and rods.
Q: What seal material is used and what pressure does this kit handle?
A: The MU 21719 uses NBR (nitrile) elastomer seals that are SAE J200 compliant and designed for mineral oil-based hydraulic fluids. The kit is rated for a maximum pressure of 3000 PSI. NBR elastomers provide reliable sealing across typical material handling hydraulic system operating ranges.
Q: What are the alternative part numbers for the MU 21719?
A: The MU 21719 is interchangeable with MT21719, MU21719, and 21719-SLIM. These part numbers reference the same OEM seal kit. When sourcing replacements, any of these cross-reference numbers will provide an equivalent direct replacement for your Multiton hydraulic system.
Q: Which Multiton pallet jack models is the MU 21719 designed for?
A: The MU 21719 is suitable for Multiton S, TM, M, and J series manual pallet jacks. The kit is specifically engineered for S model foot-control hydraulic units and their cylinder bores and rods. Verify your equipment model designation and hydraulic unit type before ordering.
Q: How does seal degradation affect pallet jack performance?
A: Worn or degraded seals cause hydraulic fluid leakage, leading to reduced system pressure, slower lifting response, or complete loss of lifting function. NBR elastomers in this kit deteriorate over time due to hydraulic fluid exposure, temperature cycling, and pressure cycling. Regular seal kit replacement maintains system reliability and load-holding capability.
