TOP SEAL
Frequently Asked Questions
Q: What is the PL 20249 top seal used for?
A: The PL 20249 is a top seal component designed for manual pallet jack hydraulic pump assemblies. It provides fluid containment at the pump head interface and prevents hydraulic oil leakage during operation. This seal is compatible with manual pallet jack models using Prestolite pump assemblies.
Q: What material is the PL 20249 seal made from?
A: The PL 20249 is manufactured from elastomer material engineered for hydraulic fluid compatibility. The specific compound is selected to withstand standard manual pallet jack operating pressures and maintain sealing integrity in mineral oil hydraulic environments.
Q: How do I know if the PL 20249 seal needs replacement?
A: Replace the PL 20249 when you observe hydraulic fluid leakage at the pump head, visible seal degradation, or reduced lifting performance on your manual pallet jack. Elastomer seals typically require replacement every 2 to 3 years depending on usage frequency and environmental conditions such as temperature extremes or contaminated storage areas.
Q: Is the PL 20249 compatible with all manual pallet jack brands?
A: The PL 20249 is a Prestolite OEM part compatible with Prestolite pump assemblies found in manual pallet jacks from multiple brands including Crown, Toyota, and Lift-Rite models. Verify your pump assembly model before ordering to confirm compatibility.
Q: What is the typical lifespan of the PL 20249 seal in storage?
A: When stored properly in a cool, dry environment away from direct sunlight and extreme temperatures, the PL 20249 seal maintains its integrity for 3 to 5 years. Environmental exposure to heat, moisture, or UV light can degrade elastomer compounds and reduce functional lifespan after installation.
