Frequently Asked Questions
Q: What components are included in SKU 800017815 seal kit?
A: This seal kit includes internal pressure seals, shaft O-rings, and dust wipers. All sealing components are molded as a matched set from NBR nitrile rubber and polyurethane composite material. The kit is designed for manual pallet jack pump cylinder assemblies.
Q: Which manual pallet jack models are compatible with this seal kit?
A: This seal kit is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and Clark with cylinder bore diameters up to 1.5 inches and rod diameters up to 0.75 inches. Verify your pump dimensions match before ordering.
Q: What is the pressure rating and material compatibility of these seals?
A: These seals are rated for pressures up to 3,000 PSI maximum working pressure and are compatible with ISO-grade hydraulic fluids in standard temperature service. The NBR and polyurethane materials provide resistance to fluid degradation and maintain seal resilience over time.
Q: How often should seals be replaced on a manual pallet jack?
A: Replace seals when the jack begins to lose pressure, shows visible hydraulic leakage, or when the handle pressure feels reduced despite a full-capacity load. Typical seal life ranges from 2,000 to 5,000 operating hours depending on hydraulic fluid condition and pump usage.
Q: Are these seals suitable for wet or cold storage environments?
A: These seals are designed for standard temperature service. For equipment operating in cold storage or wet environments, verify fluid viscosity compatibility and consider seals with specialty elastomer compounds rated for extended temperature ranges or moisture exposure.
