When handling hot exhaust, hot‑air circulation, dust fumes and mildly corrosive gas in manufacturing, automotive, rail and other heavy‑duty environments, ordinary flexible hoses often fail quickly. They become brittle under low temperature, crack under sustained high heat or collapse under negative pressure, leading to frequent replacements and higher maintenance costs.
Paishun’s Silicone Duct Hose is engineered for high‑temperature and harsh working conditions. It combines silicone’s outstanding heat resistance with high‑strength fiberglass fabric, reinforced with an embedded spiral steel wire. This unique multi‑layer construction maintains shape stability under extreme heat while keeping superior flexibility and compressibility for installation and storage.
Multi‑Layer Construction for Robust Performance
Weather‑Resistant Silicone Coating
UV‑resistant, anti‑aging and chemical‑resistant outer layer. Protects the hose against outdoor exposure and corrosive fumes to prevent surface degradation.
Glass Fiber Fabric Reinforcement
Adds excellent tensile strength and tear resistance. Resists damage from repeated bending, pulling and abrasive airborne particles.
Elastic Silicone Rubber Base Layer
Retains high elasticity even at low temperatures. Remains pliable through frequent thermal cycling without hardening.
Spiral Steel Wire Reinforcement
Prevents hose collapse under vacuum / negative pressure. Enables compression and extension for easy transportation, storage and on‑site routing.
Key Product Advantages of Passion Hose
