Frequently Asked Questions
Q: What equipment does the RL 7-99003 hydraulic seal kit fit?
A: The RL 7-99003 is an industrial-grade hydraulic seal kit engineered for Rol-Lift Series T and E manual pallet jacks with 1-3/8 inch bore hydraulic lift ram units. It is compatible with Rol-Lift 3000 lb models and some 4500 lb models. Cross-reference part numbers include RL799003, 799003, and the OEM designation T5AOK-SLIM.
Q: What is the seal material composition and pressure rating?
A: This seal kit uses nitrile rubber (NBR) with polyester backing, engineered for compatibility with standard hydraulic fluid. The unit is rated for 250 PSI operating pressure and is designed for extended service life in heavy-duty material handling applications.
Q: How long can I expect this seal kit to perform in normal warehouse use?
A: The RL 7-99003 is engineered for long service life in heavy-duty material handling environments. Actual lifespan depends on hydraulic fluid condition, operating pressure cycles, and equipment maintenance. Regular hydraulic fluid inspection and timely seal replacement prevent ram leakage and loss of lift pressure.
Q: Does this seal kit supersede any earlier part numbers?
A: Yes. The RL 7-99003 supersedes earlier seal configurations designated as 7-99003 and is equivalent to previous Rol-Lift seal kits for the same bore diameter. It represents an improved design optimized for 1-3/8 inch bore hydraulic units.
Q: Can this seal kit be used in cold storage or outdoor environments?
A: The nitrile rubber (NBR) material remains functional in cold storage and outdoor conditions typical of material handling operations. Verify that your hydraulic fluid is suitable for the temperature range of your operating environment, as fluid viscosity affects seal performance.
