It is the best part for vehicles with high load on the clutch line, such as vehicles equipped with a reinforced clutch, and vehicles that require delicate clutch operation. The core tube uses a PTFE (polytetrafluoroethylene = Teflon) hose with excellent heat, pressure, and chemical resistance, and is covered with a tough stainless steel mesh hose to suppress expansion due to internal pressure. Furthermore, by completely covering the PVC (polyvinyl chloride) tube with excellent weather resistance, the clutch line has a very tough three-layer structure. Steel fittings with the same shape as genuine hoses are used at the ends of both ends, enabling easy and reliable installation.
