The genuine XCMG 380604110 Exhaust Hose is a flexible, heat‑resistant connector used in motor grader engine turbocharger and aftertreatment systems.
This OEM 380604110 hose is manufactured from high‑temperature silicone rubber with multiple layers of polyester reinforcement, designed to handle continuous exhaust gas temperatures up to 250°C.
It connects the turbocharger outlet to the charge air cooler (CAC) or the diesel particulate filter (DPF) inlet. A cracked or leaking exhaust hose causes loss of boost pressure, black smoke, and reduced engine power.
Engineered for XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders, this hose is a direct replacement for original equipment with identical length and end configurations.
The hose features vulcanized end cuffs with wire‑reinforced beads to prevent blow‑off under peak boost pressures up to 2.5 bar (36 psi). Replacing a damaged hose with genuine XCMG 380604110 restores turbo efficiency and emissions compliance.
This component is also used in crankcase ventilation systems and EGR cooler connections. XCMG 380604110 guarantees oil‑resistant inner liner and ozone‑resistant outer cover for long service life in engine compartments.

The 380604110 exhaust hose transports compressed air from the turbocharger to the charge air cooler and then to the intake manifold. A leak here reduces boost pressure, increasing fuel consumption and black smoke.
In aftertreatment systems, this hose directs hot exhaust gases to the DPF or SCR catalyst. A rupture can cause exhaust to enter the engine bay, creating a fire hazard and emissions violations.
Replacing a cracked, oil‑soaked, or softened hose with genuine XCMG 380604110 restores full boost pressure, reduces exhaust odor, and ensures compliance with emission regulations.
This hose also dampens vibration between the turbo and rigid pipes, preventing metal fatigue and cracking of exhaust components.
Each 380604110 hose is manufactured using platinum‑cured silicone rubber, which maintains flexibility at -50°C and resists thermal aging at +250°C for thousands of hours.
Two layers of high‑tenacity polyester cord provide burst strength, while an internal steel wire helix prevents hose collapse under vacuum conditions (e.g., closed throttle).
The inner liner is formulated to resist diesel oil vapors, soot, and coolant residue. The outer cover is UV‑resistant and ozone‑resistant for long life in engine compartments.
XCMG pressure‑tests each hose to 3.5 bar (1.4× working) for 5 minutes and performs a vacuum collapse test to ensure the wire helix prevents flattening.
To replace a failed exhaust hose, allow the engine to cool completely. Loosen the hose clamps on both ends using a nut driver or socket.
Slide the hose off the fittings. Clean the metal connector surfaces with a wire brush to remove carbon deposits and old sealant.
Do not use oil or grease on the hose ends – they can cause the hose to blow off under boost. Install the new 380604110 hose and position the clamps 5‑10 mm from the end.
Torque the clamps to manufacturer specification (usually 5‑6 Nm for worm‑drive). Start the engine and check for boost leaks by listening for hissing or using soapy water.
If a hose blow‑off occurs, the turbo can over‑speed, causing catastrophic failure. Always use the correct clamp and torque. Keep a spare 380604110 hose for emergency replacement.
Visible cracks, bulging or soft spots, oil saturation (causing swelling), collapsed inner diameter (restricting flow), and soot traces around the joints indicating a leak.
Also, loss of engine power under load, black smoke from the exhaust, and a hissing sound from the engine bay. Replace immediately to avoid turbo or engine damage.
Inspect all turbo and exhaust hoses every 500 operating hours or at every oil change. Check for softness, cracking, and clamp tightness.
XCMG recommends replacing the 380604110 hose every 4,000 hours or 4 years, whichever comes first, under normal operating conditions. In high‑dust or high‑heat environments (desert, mining), replace every 2,000 hours.
Always replace the hose when the turbocharger or DPF is serviced. Never reuse an old hose – the silicone becomes brittle with heat cycles.
Keep the hose free of oil leaks from the engine – oil contamination accelerates silicone deterioration. Repair any oil leaks promptly.
Genuine XCMG 380604110 exhaust hoses are backed by a 12‑month warranty. Regional warehouses: Houston (USA), Rotterdam (Netherlands), Dubai (UAE), Shanghai (China).
Standard air freight delivers within 3‑7 business days worldwide. Express 24‑48 hour shipping available for emergency engine repairs. Bulk orders (10+ hoses) receive volume discounts.
Aftermarket hoses often use low‑grade EPDM rubber that hardens rapidly, lacks wire reinforcement, and fails under heat. Genuine XCMG 380604110 uses high‑temp silicone with steel helix for maximum durability.
Don’t risk engine power loss, turbo damage, or exhaust leaks – a failed intercooler hose can lead to major engine overhauls. Keep a genuine spare hose in your parts inventory.
Order the genuine XCMG 380604110 Exhaust Hose today and maintain full boost pressure, engine efficiency, and emission compliance for thousands of hours.
Upgrade your motor grader’s turbo system reliability with XCMG genuine silicone hoses – heat rated, wire reinforced, and leak‑tested.
