The cylinder head gasket is a key seal for XGC55 crawler crane engines (such as Weichai WD615 series or Shangchai SC7H series), which is used for gas, coolant and oil sealing between the cylinder block and the cylinder head. It adopts metal-asbestos composite material (such as steel core + expanded graphite), high temperature resistance (≤ 400 ° C), high pressure resistance (≥ 20MPa), and the design life matches the engine overhaul cycle (about 12,000-15,000 hours).
