Product Description
The RL T5AOK-SLIM is a precision hydraulic seal kit engineered for Rol-Lift T and E Series manual pallet jacks with 1-3/8 inch lift ram bore. This direct replacement kit features Nitrile (NBR) and polyurethane sealing elements designed for high-pressure hydraulic operation and compatibility with mineral hydraulic oils. The SLIM variant supersedes the standard T5AOK and is equivalent to RL 7-99003, delivering improved sealing performance and durability in manual pallet jack pump systems. Ideal for maintenance and repair of mid-range manual lift equipment.

Frequently Asked Questions
Q: What does the SLIM designation mean on the RL T5AOK-SLIM seal kit?
A: The SLIM version is a precision-engineered variant of the standard T5AOK for Rol-Lift T and E Series pump rams. It features tighter tolerances and a compact seal stack designed for high-pressure performance in T and E Series hydraulic systems. The designation refers to the geometric profile of the seal assembly.
Q: How does the RL T5AOK-SLIM compare to the standard RL T5AOK?
A: The RL T5AOK-SLIM supersedes the standard RL T5AOK. It is equivalent to RL 7-99003 and provides improved sealing performance and durability in T and E Series applications. Both fit 1-3/8 inch bore rams, but the SLIM version is the preferred modern replacement.
Q: What materials are used in the RL T5AOK-SLIM seal kit?
A: The RL T5AOK-SLIM uses Nitrile (NBR) and polyurethane sealing elements. This combination provides resistance to hydraulic fluid degradation and wear from repeated pressure cycles. Expected service life is 4-6 years under typical material handling conditions.
Q: Which Rol-Lift models use the RL T5AOK-SLIM?
A: The RL T5AOK-SLIM is designed for Rol-Lift T and E Series manual pallet jacks with 1-3/8 inch lift ram bore. These are mid-range manual jacks. Verify your jack nameplate or serial documentation lists T or E Series before ordering.
Q: What are the cross-reference part numbers for the RL T5AOK-SLIM?
A: The RL T5AOK-SLIM is cross-referenced to RL 7-99003 and also called RLT5AOK-SLIM. It supersedes the standard RL T5AOK. If you find any of these numbers in service records, they identify the same seal kit.
