Sinotruk HOWO Truck Spare Parts Wg1642820029 Cabin Steam Pressure Hose Assembly
High-Temperature Resistant | Reinforced EPDM Rubber | Direct Fit for A7/T7H Series
Ensure reliable, safe, and efficient cab heating performance with the genuine-spec Cabin Steam Pressure Hose Assembly (Part No. WG1642820029), engineered as a direct OEM replacement for SINOTRUK HOWO A7, T7H, and C7H/SITRAK heavy-duty trucks.
This critical hose connects the engine’s coolant circuit to the cab heater core, transporting hot coolant (not steam—despite the common industry misnomer “steam hose”) to provide warmth in cold climates. Designed to endure continuous exposure to high-temperature engine coolant (up to 125°C) and system pressures up to 150 kPa, it features a multi-layer reinforced EPDM rubber construction with embedded textile braid for burst resistance and long-term flexibility.
Pre-formed to match factory routing and equipped with correct-length ends and secure clamp zones, this assembly eliminates leaks, kinks, and premature failure—keeping your driver comfortable and your heating system operational during winter operations across China, Russia, Central Asia, and beyond.
