166F Gasket: "High-pressure Sealing Core" for Medium-power Engines

The 166F Gasket is an exclusive sealing part for 166F medium-power engines. Compared with the low-power 139F gasket, it uses aramid fiber material, which can withstand higher pressure and temperature.

With 50Bar pressure resistance, it perfectly adapts to the in-cylinder pressure of 166F engines, and the problem of gas leakage when ordinary gaskets are used on it is completely solved after replacement; 250℃ temperature resistance ensures the gasket won’t age and fail even if the engine runs continuously for 12 hours; the dual-hole positioning design allows one-time installation on the intake manifold interface without repeated alignment.

The 3.0kW 166F high-pressure water pump previously failed to reach the rated water pressure due to pressure leakage at the exhaust interface. After replacing this gasket, the pressure stabilized at 30Bar directly; generators using it have tight cylinder block sealing, and the power output fluctuation drops from 10% to 2%— a practical sealing accessory that "withstands high pressure" in medium-power equipment.
