Brief Introduction This PTFE‑lined metal hose is built with seamless virgin PTFE inner tube wrapped by multi‑layer stainless steel braided reinforcement. It is purpose‑built to handle highly corrosive process fluids across worldwide industrial facilities. The inner PTFE liner exhibits excellent chemical inertness, preventing chemical reactions when conveying strong acid, strong alkali and various organic solvents.

Structurally flexible, this hose can compensate axial offset, lateral displacement and angular deflection generated by pipeline thermal expansion and mechanical shaking. It relieves mechanical stress on rigid pipe connections and reduces the risk of joint fracture in circulating systems. The ultra‑smooth inner surface avoids medium accumulation and residue, making it suitable for sanitary‑critical working conditions in pharmaceutical, food and fine‑chemical processing.

Multiple end‑connection options are available, including union, flange and ferrule‑type fittings to adapt to diverse local installation standards in different countries. Both short laboratory‑use hoses and long‑run assembly for large‑scale industrial loops can be realized via custom production.
