Features of this Product
Complete Seal Set: The kit contains all the seals required to fully rebuild the hydraulic section of a Lift-Rite Titan pallet jack.
OEM-grade materials: The LF-243772 seal kit utilizes high-quality materials, including polyurethane and oil-resistant nitrile (NBR) rubber, which match or exceed Titan series OEM specifications.
Precision fit: All seals and O-rings are pre-sized to exact dimensions for Titan-series hydraulic units, ensuring they fit snugly into their respective grooves (e.g., U‑cup in the cylinder gland, O‑rings on valve seats).
Stops leaks & restores performance: Installing this kit addresses common hydraulic failures—such as slow lowering, lifting difficulties, or visible oil leaks—by restoring full pressure integrity.
Cost-effective maintenance: The LF‑243772 kit offers a budget-friendly approach to hydraulic repair—far more economical than full pump replacement and ideal for routine preventive service.
Includes critical wear components: In addition to standard seals, the kit often includes backup or anti-extrusion rings, and sometimes parts like the check-valve steel ball, covering all typical wear points for a comprehensive rebuild.
Warranty Information
1-year limited warranty. This warranty assures that the seals are free from manufacturing defects in material or workmanship.

Frequently Asked Questions
Q: How do I know if my jack needs a seal kit?
A: Common signs include hydraulic oil leaks, difficulty lifting, or slow lowering under load. If adding oil or bleeding doesn’t help, the seals may be worn. If your jack is 5 years old or older and underperforming, it’s time to rebuild it using the LF-243772 kit.
Q: Is this seal kit compatible with Big Joe or BT jacks?
A: Yes. It fits Lift-Rite Titan, Big Joe L55/PT55 (rebranded Titans), and BT LHM230/231/232 jacks. These brands share the same hydraulic design. It does not fit unrelated models, such as Crown or generic imports.
Q: How often should I replace seals?
A: Seals usually last 5–10 years. Replace when leaking, losing lift, or during regular maintenance. In high-use environments, rebuild every 3–5 years to avoid breakdowns. Inspect the hydraulic system annually and keep the hydraulic oil clean and topped off to ensure optimal performance.
Q: My jack won’t lower unless I tap the release—seal issue?
A: This usually points to a sticking release valve or misaligned linkage, not worn seals. Rebuilding helps by cleaning and resealing the valve, but also check the linkage adjustment and spring condition during reassembly.
Q: Can I reuse old seals if they look fine?
A: No. Seals that have been used lose their elasticity and shape, thereby reducing their sealing effectiveness. Always use new seals from the kit. Reusing old ones can cause leaks and wasted effort. Only metal hardware, such as springs or washers, should be reused.
Q: Will this kit fix leaks from the top of the cylinder under load?
A: Yes. That’s a classic symptom of a worn ram seal. The kit includes a new main cylinder seal and wiper. Ensure the piston rod is smooth and the top cap is tightened properly during reassembly.
Q: Any adjustments needed after installing new seals?
A: No calibration is required, but check fluid level, bleed air, and adjust the release linkage if needed. The jack should lift and lower smoothly after being rebuilt. Overload valves are factory-set and usually don’t need adjustment.
