Frequently Asked Questions
Q: What is the AT 2016B and which Atlas models does it fit?
A: The AT 2016B is a U-Cup seal designed for Atlas manual and electric pallet jacks. This compound seal is used in hydraulic cylinders and pump assemblies to create pressure-tight seals under dynamic load conditions.
Q: What is the difference between a U-Cup seal and an O-Ring?
A: The AT 2016B U-Cup has a different geometry than O-Ring seals. U-Cup seals accommodate larger pressure differentials and work better in rod-side applications. O-Rings are typically used in static or lower-pressure ports. Confirm which seal type your equipment requires.
Q: What is the material composition of the AT 2016B U-Cup?
A: The AT 2016B is manufactured from elastomer compound formulated for high-pressure hydraulic service. The material provides dynamic sealing capability and resists extrusion under the pressure cycling typical in pallet jack cylinders.
Q: What is the typical service life of the AT 2016B?
A: The AT 2016B typically lasts 2-3 years depending on load intensity and pump pressure settings. Rod-side seals wear faster than stationary seals due to dynamic motion. Replace when external leakage appears or cylinder drift becomes noticeable.
Q: How do I know if the AT 2016B needs replacement?
A: Replace the AT 2016B when you observe oil leakage from the cylinder rod area, the mast drifts down without manual operation, or pump pressure drops significantly. Early replacement prevents fluid loss and maintains equipment reliability.
