JT PT2748W-58

Frequently Asked Questions

Q: What is the JT PT2748W-58 U-Cup and what does it do?
A: The JT PT2748W-58 is a U-Cup seal component for Jet model W manual pallet jacks. It functions as a dynamic seal in the hydraulic pump assembly, preventing fluid leakage and maintaining pressure integrity during lift and lower cycles. The U-shaped profile allows it to compress and expand with the rod stroke.

Q: Which Jet pallet jack models does the JT PT2748W-58 U-Cup fit?
A: The JT PT2748W-58 is designed specifically for Jet model W series manual pallet jacks. Verify your equipment carries the model W designation before ordering to ensure compatibility with your pump assembly.

Q: What material is the JT PT2748W-58 U-Cup made from?
A: The JT PT2748W-58 U-Cup is typically manufactured from nitrile or polyurethane elastomer compounds selected for chemical resistance to hydraulic fluid and durability under repeated compression cycles common to pallet jack service.

Q: How long does the JT PT2748W-58 U-Cup seal typically last?
A: Lifespan depends on operating conditions and frequency of use. Under normal industrial service, expect 2 to 5 years. Frequent operation in cold storage or exposure to contaminated hydraulic fluid shortens seal life. Inspect annually for signs of hardening, cracking, or fluid weeping at the pump rod.

Q: What symptoms indicate the JT PT2748W-58 U-Cup needs replacement?
A: Common failure signs include visible hydraulic fluid leaking from the pump rod area, loss of lift height or inability to hold load, sluggish pump response, or visible cracks and hardening of the seal material. Any of these symptoms warrants immediate replacement to prevent pump damage.

Q: Are there cross-reference or equivalent part numbers for the JT PT2748W-58?
A: The JT PT2748W-58 is the OEM part number for Jet model W pallet jacks. Verify fitment with your specific equipment serial range to ensure proper replacement. Contact our parts team if you need compatibility confirmation for your jack.
