Frequently Asked Questions
Q: What equipment does the 805-603-STD hydraulic seal kit fit?
A: The 805-603-STD is a precision hydraulic seal kit designed specifically for Blue Giant PT-50 and PT-55 manual pallet jack hydraulic units. Cross-reference part numbers include BG805603 and BG 805-603-SUPER.
Q: What is the pressure rating of the 805-603-STD seal kit?
A: The 805-603-STD seal kit is rated for 3000 PSI maximum operating pressure. Nitrile (NBR) elastomer seals maintain integrity within this range when used with compatible hydraulic fluid.
Q: What type of hydraulic fluid does the 805-603-STD use?
A: The 805-603-STD seal kit is compatible with mineral oil hydraulic fluid meeting ISO VG 32 or ISO VG 46 specifications. Do not substitute with non-mineral fluids as they will damage the nitrile seals.
Q: What components are included in the 805-603-STD seal kit?
A: The 805-603-STD includes piston seal, gland seal, quad ring, seat, snap ring, and retainer components. All seals are engineered for tight fit specifications of plus 0.005 inch, minus 0.000 inch tolerance.
Q: When should I replace the 805-603-STD hydraulic seal kit?
A: Replace the 805-603-STD when the hydraulic cylinder shows signs of external leakage, reduced lift speed, or inability to hold load. Seal degradation accelerates with age, heat, and contaminated fluid.
Q: What seal material is the 805-603-STD made from?
A: The 805-603-STD uses nitrile (NBR) elastomer seals, which provide excellent chemical resistance to mineral oil hydraulic fluids and maintain flexibility across typical warehouse temperature ranges.
