Frequently Asked Questions
Q: What is included in the AT PT2748W-94 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 in PT2748W pump units without requiring component-by-component sourcing.
Q: What is the pressure rating for the AT PT2748W-94 seals?
A: The AT PT2748W-94 seal kit is rated for up to 3000 PSI hydraulic system pressure, which covers all standard manual pallet jack pump applications. The NBR material provides reliable sealing performance across this pressure range. If your system operates beyond 3000 PSI, confirm with equipment manufacturer specifications.
Q: Which Atlas and Jet pallet jack models use the AT PT2748W-94?
A: The AT PT2748W-94 fits Atlas EZ Lift manual pallet jacks with Model W hydraulic units and compatible Jet W Series pallet jacks using PT2748W pump assemblies. Cross-reference equivalent part numbers include PT2748W-94 and JT PT2748W-94-C custom kit. Verify your pump unit model before ordering.
Q: When should seals in the AT PT2748W-94 kit be replaced?
A: Replace seals when the pump or cylinder exhibits internal leakage (pressure loss over time without use), 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. Replace the complete seal kit to ensure consistent performance.
Q: Is the AT PT2748W-94 an OEM part or aftermarket?
A: The AT PT2748W-94 is an OEM-compliant replacement kit. The OEM part number is AT PT2748W-94 and the manufacturer part number is ATPT2748W-94. This is the original Atlas specification seal kit, making it a genuine OEM option for Atlas EZ Lift maintenance.
Q: What material are the seals in this kit?
A: The AT PT2748W-94 kit contains NBR (Nitrile) O-rings and high-pressure seals. NBR provides excellent resistance to standard hydraulic fluids and maintains flexibility across typical pallet jack operating temperatures. The material is compatible with mineral-based hydraulic oils used in manual pump systems.
