HL 158H

Frequently Asked Questions

Q: What equipment does the HL 158H O-ring fit?
A: The HL 158H is an O-ring seal engineered for Hu-Lift manual pallet jacks, specifically the HP25L model. It is not compatible with other manufacturers without verification of seal dimensions and cavity specifications.

Q: What material is this O-ring manufactured from?
A: The HL 158H is manufactured from high-durability elastomeric material suitable for hydraulic and pneumatic applications in industrial material handling equipment. The exact compound varies based on production lot, but all units meet Hu-Lift OEM specifications.

Q: Where does this O-ring seal in the HP25L pallet jack?
A: The HL 158H provides sealing at critical pressure points within the hydraulic unit of the HP25L. It prevents fluid leakage and maintains proper hydraulic pressure during operation.

Q: How long does an HL 158H typically last in service?
A: Lifespan depends on frequency of use, load cycles, and operating conditions. In standard industrial applications with routine maintenance, expect 2-4 years of service. Premature failure occurs with contaminated hydraulic fluid or excessive load cycling.

Q: Can I use this seal in cold storage or outdoor environments?
A: The HL 158H is rated for indoor and outdoor industrial service within standard temperature ranges. Extended cold storage or extreme temperature fluctuations may affect elastomer performance and require verification before deployment.
