Volvo D11 / D13 EGR Cooler – One of Many Applications We Support Modern heavy-duty diesel engines rely on efficient cooling systems to meet strict emission standards. One key component is the EGR (Exhaust Gas Recirculation) Cooler, which reduces exhaust gas temperature before it is recirculated into the engine, helping lower NOx emissions while maintaining engine performance. The Volvo D11 and D13 EGR Cooler features four functional ports, each connected to a dedicated pipeline within the engine system: ·Exhaust Gas Inlet (Large Flange – Left Side)  ·Connected to the engine exhaust manifold via a metal exhaust pipe. ·Carries high-temperature exhaust gases into

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
