The 380601931 Intake Hose is a genuine XCMG engine air intake hose designed for GR series motor graders. This high-quality hose ensures clean, unrestricted airflow from the air filter to the turbocharger or intake manifold. The 380601931 intake hose is manufactured from high-grade silicone rubber with embedded textile reinforcement, providing excellent durability in dusty grading environments. For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining proper air-fuel ratio and engine performance.
The 380601931 Intake Hose is manufactured to SAE J20R3 standards, with a nominal inner diameter of 76 mm and a wall thickness of 4 mm. The hose features a smooth inner bore to minimize flow restriction and a corrugated outer section for flexibility in tight engine bays. Both ends are reinforced with embedded wire to prevent collapse under vacuum. As a genuine XCMG part, it matches the original shape, length, and connector sizes exactly.
Engineered for extreme durability, the 380601931 Intake Hose has a temperature range of -50°C to +180°C and resists ozone, oil mist, and engine heat. The silicone rubber construction remains flexible for years, unlike conventional rubber that hardens and cracks. Each hose is 100% inspected for dimensional accuracy and burst strength. Using genuine XCMG intake hoses prevents leaks that can allow unfiltered air into the engine, causing premature wear and power loss.

Aftermarket intake hoses often use cheap rubber that hardens, cracks, or collapses under vacuum. The genuine 380601931 Intake Hose from XCMG is constructed from high-performance silicone that remains flexible even after years of heat cycling. Independent tests show that OEM hoses withstand 5,000 hours of thermal aging without cracking, while generic hoses may fail in 500 hours. This reliability prevents unfiltered air ingestion and turbocharger damage.
Each 380601931 Intake Hose is traceable to its production batch, with records of material batch and pressure decay tests. The hose is printed with the XCMG part number and date code for easy identification. XCMG’s quality control includes 100% dimensional inspection and random sampling for burst pressure testing. Only hoses that meet all specifications are shipped, ensuring a perfect fit and long service life.
Installing the 380601931 Intake Hose requires the engine to be cool. Remove the old hose and clean the turbocharger inlet and air cleaner outlet. Lightly lubricate the inside of the new hose with silicone spray. Slide the hose onto both fittings, ensuring it is not twisted. Tighten the clamps to 5 Nm (44 in-lbs) – do not overtighten, as silicone can be cut. Ensure the hose does not contact sharp edges.
Inspect the 380601931 Intake Hose every 500 hours for signs of cracking, soft spots, or internal delamination. Replace immediately if any damage is visible. When replacing the air filter, also check the inside of the hose for dust or oil residue. Store spare hoses in a cool, dark place away from ozone sources. Keep a spare intake hose in your parts inventory, as a failed hose can cause sudden loss of power and dust ingestion.
A cracked or collapsed intake hose restricts airflow, causing black smoke, low power, and poor fuel economy. The genuine 380601931 Intake Hose restores full air volume to the engine, improving throttle response and reducing exhaust emissions. Operators report cleaner combustion and faster acceleration after replacing a damaged hose. The smooth inner bore also minimizes flow turbulence, helping the turbocharger spool faster.
In a fleet study of 20 XCMG GR215 graders, those equipped with genuine 380601931 Intake Hoses experienced 70% fewer intake-related engine issues over 4,000 hours compared to machines with aftermarket hoses. The improved sealing also prevented turbocharger overspeed conditions caused by leaks. For contractors who operate in dusty environments, an OEM intake hose is essential for protecting the engine investment.
XCMG’s hose plant uses CNC mandrel winding to produce the 380601931 Intake Hose with consistent wall thickness and embedded reinforcement. The silicone compound is mixed in-house and cured in a heated autoclave for uniform cross-linking. The wire helix is molded into the rubber to prevent collapse under high vacuum. After curing, each hose is trimmed and cleaned with ionized air. Finally, a 100% visual inspection and pressure decay test ensure zero defects.
All 380601931 Intake Hoses are individually packaged in plastic bags with a desiccant and shipped in cardboard boxes. Bulk orders of 5 or more hoses are packed in wooden crates. XCMG’s global logistics network ensures delivery within 5-7 business days. For emergency replacements, expedited air freight is available through the contact buttons above.
The 380601931 Intake Hose directly replaces original part numbers 380601930 and 380601932. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders equipped with Dongfeng Cummins 6BTAA5.9 engines. This hose is also used on some XCMG wheel loaders with the same engine. For machines with the larger 8.3L engine, use part 380601933. Always verify your engine serial number before ordering.
When replacing the intake hose, also order new constant-tension clamps (part 380601934) and inspect the turbocharger inlet for damage. XCMG recommends changing the air filter at the same time. Keep one spare 380601931 Intake Hose in your service truck for emergency repairs. For fleet operators, bulk orders of 10 or more hoses include a 10% discount and free shipping.
For custom lengths or alternative materials (e.g., high-temperature aramid reinforcement), use the buttons above to contact our technical sales team. We can also supply hoses with different bend angles. Always provide your grader’s serial number and a photo of the original hose when ordering the 380601931 Intake Hose to ensure perfect fitment.
