Frequently Asked Questions
Q: What equipment does the BJ 10279 ball and valve kit fit?
A: The BJ 10279 is designed for Lift-Rite L-50 manual pallet jacks and hydraulic assemblies. Cross-reference part numbers include LF 10279 and LR 10279. Verify your equipment model is L-50, L 50, or Lift-Rite L50 before ordering.
Q: What is the pressure rating for the BJ 10279 kit?
A: The BJ 10279 ball and valve kit is rated for maximum working pressure of 3,000 PSI. This specification applies to the complete hydraulic system. Do not exceed rated pressure to avoid component failure or seal degradation.
Q: What materials are used in the BJ 10279 components?
A: The kit includes a hardened chrome steel ball per ASTM A295, a machined carbon steel valve seat with nitrided finish, and an NBR elastomer seal. These materials are OEM-quality and engineered for hydraulic pressure applications and corrosion resistance in material handling environments.
Q: How does the nitrided steel valve seat perform compared to standard carbon steel?
A: Nitriding enhances surface hardness and wear resistance. The nitrided valve seat in the BJ 10279 provides improved resistance to abrasive particles and extends component lifespan under cyclic pressure loading typical of manual pallet jack operations.
Q: Is the BJ 10279 an OEM or aftermarket part?
A: The BJ 10279 is manufactured to OEM specifications and includes OEM-quality materials including hardened chrome and nitrided components. It serves as a direct replacement for original Lift-Rite L-50 ball and valve kits.
