4. FAQ
Q: What is this gasket, and what does it do?
A: This is a flat flange gasket, typically used in hydraulic or engine applications (like cylinder heads, pump covers, or valve bodies). It creates a tight, leak-proof seal between two mating metal surfaces. By filling in small surface imperfections, it prevents fluid (oil, hydraulic fluid, coolant) or gas from escaping the joint, while also preventing contaminants from entering.
Q: Can I reuse this gasket?
A: No, it is never recommended to reuse a flat fiber gasket. Once it has been compressed by the bolts, it takes a permanent set and loses its elasticity. When you disassemble the joint, the gasket will not be able to conform to the mating surfaces again, leading to leaks. Always install a new gasket during every rebuild.
Q: How long does a normal gasket last on construction machines?
A: If installed correctly and working under normal temperature and pressure, it can last several years. It only needs replacement when disassembling maintenance or obvious oil leakage appears.
