Frequently Asked Questions
Q: What does the AT Z-1150 back-up ring do in an Atlas Zenith pallet jack?
A: The AT Z-1150 is a back-up ring (or backup ring) used in Atlas Zenith Type 9 manual pallet jack hydraulic units. Back-up rings support primary O-ring seals and prevent extrusion of seals under high hydraulic pressure, improving seal longevity.
Q: Which Atlas models use the AT Z-1150 back-up ring?
A: The AT Z-1150 is designed for Atlas Zenith Type 9 manual pallet jacks. This is an OEM original equipment manufacturer part. The AT Z-2188 complete seal kit for Zenith Type 9 includes the AT Z-1150.
Q: Is the AT Z-1150 back-up ring material resistant to hydraulic fluid?
A: Yes. The AT Z-1150 is manufactured from materials formulated to resist degradation from hydraulic oils. Back-up rings must maintain rigidity and cannot absorb or swell from prolonged fluid contact.
Q: Can I order the AT Z-1150 separately or must I buy the complete seal kit?
A: The AT Z-1150 is available as an individual part. However, if your hydraulic unit requires seal replacement, ordering the complete AT Z-2188 seal kit ensures all worn components are replaced together, preventing premature failure.
