Frequently Asked Questions
Q: What is the MO 12X3076 U-Cup seal and where is it used?
A: The MO 12X3076 is a U-Cup hydraulic seal designed for use in the hydraulic pump and cylinder assemblies of Mobile manual pallet jacks. The U-Cup profile creates a dynamic seal between moving and stationary surfaces, preventing hydraulic fluid leakage while allowing controlled piston motion. It is a critical component for maintaining system pressure.
Q: Which Mobile pallet jack models use the MO 12X3076 seal?
A: The MO 12X3076 is compatible with Mobile ML45, Mobile ML55, and Mobile MLX55 manual pallet jack models. These models share similar hydraulic pump and cylinder designs but may have variations in seal kit configuration. Verify your specific model and serial range before ordering, as some variants use different seal part numbers.
Q: What causes U-Cup seals like the MO 12X3076 to fail?
A: U-Cup seals fail due to wear from repeated compression cycles, exposure to contaminated hydraulic fluid, temperature extremes, or mechanical damage during installation. Symptoms include gradual pressure loss, external hydraulic fluid dripping at pump or cylinder ports, or inability to hold load at height. Replacing seals before complete failure prevents damage to pistons and cylinders.
Q: Is the MO 12X3076 sold as a single seal or as part of a seal kit?
A: The MO 12X3076 is available as an individual seal component. However, when performing hydraulic system repairs, technicians typically replace all seals in the pump and cylinder assemblies at the same time to prevent repeat failures. Check your equipment manual for complete seal kit part numbers that include all required seals for a full system refresh.
Q: What material is the MO 12X3076 seal made from?
A: The MO 12X3076 is typically manufactured from elastomer material, usually Nitrile (Buna-N) rubber, which provides good chemical resistance to standard mineral-based hydraulic fluids used in pallet jacks. Elastomer seals are temperature-resistant and maintain flexibility under the pressure and temperature conditions found in warehouse and dock equipment.
