A seal ring for a nozzle holder is a sealing component used in the fuel injection system. Its function is to ensure a leak-free connection between the nozzle holder and surrounding components, preventing fuel or combustion gas leakage.
Key specifications include inner and outer diameter, thickness, material (such as heat- and fuel-resistant rubber, FKM, or metal), temperature resistance, pressure rating, and compatibility with the injection system. It must withstand high pressure and extreme temperatures.
Replacement is necessary when the seal is worn, damaged, or leaking. It is also recommended to replace it whenever the nozzle holder or injector components are removed or serviced.
