5. FAQ

Q: What four different core raw materials form all varied gaskets inside this complete repair package?
A: The whole kit is composed of high-density non-asbestos composite fiber sheet, high heat resistant FKM fluororubber, metal-clad flexible graphite panel and heat-resistant closed-cell silicone sponge tailored for diverse engine sealing positions.

Q: What natural inherent color does each category of gasket display without artificial pigment coating?
A: Non-asbestos fiber gaskets are uniform grayish beige, FKM rubber gaskets are deep reddish brown, metal wrapped graphite gaskets are silver-gray with dark graphite core, silicone sponge gaskets are semi-transparent off-white.

Q: What core sealing application does non-asbestos composite fiber gasket undertake inside the diesel engine?
A: As the most widely used basic gasket material, fiber gaskets are mainly arranged for cylinder head, intake manifold and oil pan mating surfaces to block engine oil, cooling liquid and intake gas leakage under regular engine alternating operating temperature.

Q: What specific installation scenarios require FKM rubber gaskets from this complete kit?
A: FKM gaskets are reserved for high-temperature exhaust manifold joints and fuel injector base sealing positions, which keep long-term contact with high-temp exhaust gas and aged diesel fuel during continuous heavy-load engine operation.

Q: What prominent sealing advantages make metal-coated graphite outperform ordinary fiber gaskets?
A: Metal-clad graphite owns outstanding compressibility and heat conduction performance, able to compensate unevenness of rough engine casting flange surfaces and maintain stable tightness under dramatic temperature rise after engine ignition and heat accumulation.
