Frequently Asked Questions
Q: What material is the BG 107-781 O-Ring manufactured from?
A: The BG 107-781 is manufactured from nitrile butadiene rubber (NBR) formulation. Nitrile is the standard elastomer for hydraulic seals in manual pallet jack systems due to its resistance to mineral oils and hydraulic fluids used in PT-50, PT-55, PT-106, and ROI series units.
Q: Which Blue Giant pallet jack models does this O-Ring seal fit?
A: The BG 107-781 O-Ring fits Blue Giant PT-50, PT-55, PT-106 manual pallet jacks and ROI-5, ROI-55 hydraulic units, as well as the MTS 2000 series. Verify your specific hydraulic unit model before ordering to ensure correct fitment.
Q: Is the BG 107-781 a static or dynamic seal?
A: The BG 107-781 functions as a static seal in the hydraulic system. Static seals remain stationary and prevent leakage at fixed connection points within the hydraulic unit rather than accommodating moving parts.
Q: Are there any cross-reference or superseding part numbers for the BG 107-781?
A: No known cross-reference or superseding part numbers exist for the BG 107-781. This is the OEM part number directly from Blue Giant. When ordering replacement seals for PT-50, PT-55, PT-106, ROI-5, ROI-55, or MTS 2000 hydraulic units, specify BG 107-781.
Q: What causes hydraulic seal failure in manual pallet jacks?
A: Seal failure typically results from prolonged oil exposure, thermal cycling, mechanical compression from repeated lift cycles, or contamination in the hydraulic fluid. If your PT-50 or PT-55 is losing hydraulic pressure or leaking fluid around the cylinder area, the O-Ring may require replacement.
