👉 The headset fluid, also known as silicone or Teflon-based fluid, is a specialized lubricant used in headset assemblies to ensure smooth operation and longevity of the components. It fills the gaps between the headset's moving parts, such as the crankshaft and camshaft, and the connecting rods, reducing friction and wear. This fluid acts as a protective barrier against metal-to-metal contact, dissipating heat generated during operation and preventing corrosion. Its low viscosity allows for easy lubrication even under high-speed conditions, while its non-reactive nature ensures compatibility with various materials in the engine. By maintaining a consistent lubrication level, headset fluid minimizes noise, vibration, and potential damage, contributing to the overall efficiency and durability of the engine.
