Frequently Asked Questions
Q: What is the HL 32 backup ring material and why is it split?
A: The HL 32 is fabricated from engineering-grade split nylon. The split design allows easy installation around existing components without disassembling the hydraulic joint, saving service time on Hu Lift pallet jacks.
Q: What is the function of the HL 32 backup ring in a hydraulic seal assembly?
A: The HL 32 provides extrusion protection for primary seals in dynamic and static hydraulic joints. It prevents seal extrusion into clearance gaps under pressure, extending seal life and maintaining system integrity.
Q: What hydraulic fluids is the HL 32 compatible with?
A: The HL 32 engineering-grade nylon is formulated for compatibility with ISO VG 46 mineral oil hydraulic fluids standard in manual pallet jack systems. Verify your system fluid type before use.
Q: Which Hu Lift pallet jack models use the HL 32 backup ring?
A: The HL 32 is designed for Hu Lift HP25L manual pallet jacks. Confirm your equipment model matches before ordering to ensure correct fitment and seal compatibility.
Q: What is the service life of the HL 32 split nylon backup ring?
A: The HL 32 service life depends on operating pressure, fluid type, and temperature cycles. Under standard manual pallet jack conditions, expect 2-3 years typical use. Replace it if the primary seal fails or during routine seal kit replacement.
