AZ160084000001 Warm Air Water Pipe for Sinotruk Cab – OEM Heater Hose Assembly
High-Temperature Coolant Line | Reinforced EPDM Rubber | Direct Replacement for Reliable Winter Comfort
Keep your cab warm and your driver comfortable—even in sub-zero conditions—with the genuine-spec Warm Air Water Pipe (Part No. AZ160084000001), engineered as a direct OEM replacement for the cab heater circuit in SINOTRUK HOWO A7, T7H, TX, and SITRAK C7H/G7H heavy-duty trucks.
Despite its common name, this is not a steam line—it’s a coolant circulation hose that transports hot engine coolant (typically 80–95°C) from the engine block to the cab-mounted heater core, enabling efficient cabin heating. Designed to exact factory specifications, this pre-formed assembly ensures leak-free performance, optimal flow, and long service life under continuous thermal and pressure stress.
Constructed with multi-layer EPDM (Ethylene Propylene Diene Monomer) rubber, reinforced with high-strength textile braid, and finished with a UV- and ozone-resistant outer cover, this hose withstands temperatures up to 125°C continuously and resists degradation from ethylene glycol-based coolants, road salts, and engine oils.
