Basic Information

· Part Number: 54270370

· Product Name: Sealing Gasket / Flat Gasket

· Applicable Brand: Hitachi

· Application: Hitachi construction machinery, excavator hydraulic assemblies, engine piping, pump and valve connection surfaces

Product Features

    Premium Sealing Material Manufactured from high-density composite sealing material, with outstanding oil resistance, coolant resistance, high temperature resistance and compression rebound performance. It maintains stable sealing under long-term hydraulic pressure and fluctuating working temperature, effectively blocking leakage of hydraulic oil, engine oil and cooling liquid

    OEM Matching Precision Produced strictly according to Hitachi original drawing standards, consistent with the size, hole position and thickness of original part 54270370. Perfect fit on assembly mating surfaces without modification, avoiding installation gaps caused by mismatched accessories.

     Long Service Life & Anti-Aging Anti-oxidation and anti-corrosion treatment on the surface, resistant to aging, hardening and cracking under harsh construction site environments (dust, vibration, high & low temperature). Reduces frequent replacement frequency and cuts maintenance downtime cost.

   Vibration Buffering & Protection Absorbs mechanical vibration between two metal contact surfaces during equipment operation, relieves metal friction and wear, protects pump, valve and engine components, and extends the overall service life of Hitachi machinery
