Frequently Asked Questions
Q: What seals are included in the 800035450 Super Seal Kit?
A: The 800035450 Super Seal Kit contains OEM-grade hydraulic seals for manual pallet jack cylinder and valve assemblies. The kit includes primary seals in nitrile rubber (NBR) and secondary seals in thermoplastic polyurethane (TPU). These seals prevent hydraulic fluid leakage and maintain system pressure.
Q: What pressure rating and temperature range does this seal kit support?
A: The 800035450 seals are rated for hydraulic systems up to 3000 PSI and support a wide operating temperature range. The kit is ISO and ASTM compliant for elastomeric performance standards. This rating covers standard warehouse pallet jacks and most industrial material handling equipment.
Q: What hydraulic fluid type is compatible with these seals?
A: The 800035450 seals are compatible with mineral-based hydraulic oil containing anti-wear additives. Using the correct hydraulic fluid type is critical for seal lifespan. Incompatible fluids can degrade seals prematurely, causing leaks and system failure.
Q: How long do these seals last and what causes premature failure?
A: With proper hydraulic fluid maintenance, NBR and TPU seals typically last 3-5 years or 10,000+ operating hours. Premature failure occurs from contaminated hydraulic fluid, incorrect fluid type, overheating, external damage, or exceeding pressure ratings. Regular fluid analysis and condition monitoring extend seal life.
Q: What are the symptoms of failed seals in a pallet jack?
A: Failed seals cause visible hydraulic fluid leaks from the cylinder, valve, or pump area. You may also notice a loss of lifting pressure, slower raising or lowering speed, or inability to hold load at height. Any external hydraulic leak indicates seal failure and the need for kit replacement.
Q: Is the 800035450 compatible with different pallet jack brands?
A: The 800035450 is designed as an OEM-grade seal kit for multiple pallet jack models. Confirm your equipment brand and model before ordering. Contact us with your pallet jack specifications and cylinder part number, and we can verify if this kit fits your system.
