Frequently Asked Questions
Q: Which models is the AT PT2748W-94 compatible with?
A: The AT PT2748W-94 is compatible with Atlas EZ Lift, Jet W Series, and Dayton manual pallet jacks using PT2748W, PT2748LW, PT2748L, PTW-2036, PTW-2042, PTW-2048, PTW-2742, PTW-2748, and 4YX96 hydraulic pump assemblies.
Q: What material are the seals in this kit made of?
A: The AT PT2748W-94 contains NBR (Nitrile) O-rings and high-pressure seals. This material provides excellent resistance to standard hydraulic fluids and maintains flexibility across typical operating temperatures.
Q: When should I replace the seals in this kit?
A: Replace the seals when you notice internal leakage, external fluid weeping from pump housing or cylinder rod seals, or reduced lift speed and force. Seal degradation typically occurs after 5-10 years of regular use depending on storage conditions and operating frequency.
Q: What is the pressure rating for this seal kit?
A: The AT PT2748W-94 is rated for up to 3000 PSI hydraulic system pressure, which covers all standard manual pallet jack pump applications. If your system operates beyond 3000 PSI, confirm with the equipment manufacturer specifications.
Q: What is included in this seal kit?
A: The AT PT2748W-94 is an O-ring and seal kit containing NBR (Nitrile) O-rings and high-pressure seals designed for hydraulic cylinders and pump assemblies. The kit includes all internal sealing components required to restore hydraulic containment and pressure performance.
