Frequently Asked Questions
Q: What is the JT PT2748J-016 and what function does it perform?
A: The JT PT2748J-016 is the OEM U-Cup lift ram seal for Jet PT2748J series manual pallet jacks. This seal sits inside the hydraulic cylinder and maintains pressure during lift and lower cycles. The U-Cup design creates a dynamic seal around the lift ram rod, preventing internal hydraulic fluid leakage.
Q: Which Jet pallet jack models use the JT PT2748J-016 seal?
A: The JT PT2748J-016 is validated exclusively for Jet PT2748J series manual pallet jacks. No cross-referenced or superseded part numbers are documented in approved sources. This is a direct-fit OEM part only for the PT2748J model. Do not assume compatibility with other Jet frame designations such as A, L, or J models.
Q: What material is the U-Cup seal made from and how long does it last?
A: OEM Jet U-Cup seals are molded from polyurethane or Buna-N compounds designed for hydraulic pressure retention. Under normal warehouse duty, lift ram seals typically perform for 3 to 5 years. Seal failure accelerates if hydraulic fluid contains water, debris, or if the lift ram rod develops corrosion or scoring. Signs of imminent failure include loss of lifting pressure or slow descent.
Q: How do I know if the lift ram seal needs replacement?
A: Symptoms of lift ram seal failure include: pallet jack fails to lift under full lever pump pressure, hydraulic fluid visible leaking from cylinder base, lift platform slowly descends when held at height, or hissing sound during lift operation. If any of these occur, the U-Cup seal has degraded and requires immediate replacement to restore equipment function.
