A standout feature of Polytetrafluoroethylene tube is its self-locking spiral hose protection, typically made from high-quality stainless steel. This protective layer further enhances the durability of the tube, ensuring it is shielded against physical damage caused by pressure, abrasion, impacts, or vibrations. The self-locking mechanism works by tightly securing the tube, preventing any undesired loosening or damage under stress.
This innovative feature makes PTFE tubes particularly useful in high-pressure and vibration-prone environments, such as hydraulic systems, fuel lines, and pressure vessels, where the tube is likely to be exposed to both mechanical stress and high internal pressure.
The stainless steel construction of the protective layer further ensures that the tube remains protected from external forces, significantly extending the service life of the tube and reducing the risk of system failure due to material wear.
Flexibility in Harsh Conditions
One of the unique properties of Polytetrafluoroethylene tube is its flexibility, which distinguishes it from other materials like metal pipes or rigid plastic tubing. Despite its high tensile strength and durability, PTFE tube maintains excellent flexibility, even under high-pressure conditions. This ensures that PTFE tubes are easy to install, even in tight spaces or systems with complex designs.
Unlike rigid materials that may crack or fracture when subjected to bending or movement, Polytetrafluoroethylene tube retains its shape and flexibility.
