401627

Frequently Asked Questions

Q: What is the 401627 RL Super Seal Kit used for?
A: The 401627 is a complete elastomeric seal kit for RL-type manual hydraulic pallet jack pump repair. It provides dynamic and static sealing surfaces for internal pump cavities, controlling hydraulic fluid flow while preventing leakage at rated system pressure.

Q: What hydraulic fluid is the 401627 compatible with?
A: The 401627 is engineered for ISO VG 46 hydraulic oil and equivalent mineral oil-based fluids. The elastomeric materials provide broad fluid compatibility and maintain seal integrity across standard industrial hydraulic oil specifications.

Q: What pressure rating does the 401627 support?
A: The 401627 is designed for hydraulic systems rated at 3000 PSI. All seals are manufactured to maintain zero visible leakage under maximum system pressure during full-load lifting and load-holding operations.

Q: Which manual pallet jack models accept the 401627 seal kit?
A: The 401627 is engineered for RL-type pump assemblies found in manual hydraulic pallet jacks from OEM brands including Crown, Toyota, Raymond, Yale, and Hyster. Verify your pump model designation and port configuration before ordering to ensure proper fitment.

Q: How long does the 401627 seal kit maintain performance?
A: Typical seal life is 6 to 10 years with proper hydraulic maintenance. Seals degrade faster in contaminated fluid or high-temperature environments. Replace the 401627 when you observe slow lifting, pump cavitation, or visible hydraulic leakage from pump ports.

Q: Is the 401627 an OEM replacement?
A: Yes, the 401627 is manufactured to OEM specifications for direct replacement in original RL-type pump assemblies. The seal kit provides equivalent performance and durability to original equipment seals while maintaining full compatibility with 3000 PSI hydraulic systems.
