Frequently Asked Questions
Q: What equipment does the AC326 O-Ring fit?
A: The AC326 is an O-Ring designed for Noblelift model AC55 pallet jacks. Alternate model designations AC55, AC-55, and AC 55 all refer to the same equipment. Verify your model before ordering.
Q: What is the purpose of the AC326 O-Ring in a pallet jack system?
A: The AC326 O-Ring seals hydraulic connections and prevents fluid leakage at pump, valve, or cylinder ports. It is a critical component for maintaining system pressure and operational efficiency on the AC55.
Q: What material is the AC326 O-Ring made from?
A: The AC326 is typically an elastomer (natural or synthetic rubber) O-Ring formulated to resist hydraulic fluid, heat, and pressure cycles. The compound is compatible with standard ISO hydraulic oils.
Q: How long does the AC326 O-Ring typically last?
A: Under normal operating conditions on the AC55, the AC326 can last several years. Lifespan depends on usage frequency, hydraulic fluid condition, and temperature. Replace it when fluid leakage occurs or during preventive maintenance cycles.
Q: Is the AC326 O-Ring compatible with other pallet jack brands?
A: The AC326 is specific to Noblelift AC55 equipment. Do not use it as a substitute on Crown, Toyota, Raymond, Hyster, or other manufacturers. O-Ring size, pressure rating, and installation position differ across brands.
Q: What indicates the AC326 O-Ring needs replacement?
A: Replace the AC326 if you observe hydraulic fluid dripping or leaking from pump or valve connections on your AC55, if the jack loses pressure under load, or if the O-Ring appears cracked, hardened, or discolored during inspection.
