The 803190341 Hose Clamp is a genuine XCMG heavy-duty clamp designed for motor grader hydraulic and coolant hose systems. This clamp securely fastens hoses to chassis brackets, preventing chafing and disconnection under vibration. The 803190341 hose clamp features a spring-loaded design with a rubber cushion, providing constant tension while protecting the hose outer cover. It is a critical component for maintaining reliable fluid conveyance on GR series graders.
The 803190341 Hose Clamp is manufactured from zinc-plated carbon steel with a vulcanized EPDM rubber insert. The clamp has a nominal diameter range of 25-32mm, suitable for 1-inch to 1.25-inch hoses. The spring mechanism maintains a consistent clamping force of 200N, compensating for hose compression and thermal expansion. As a genuine XCMG part, it matches the original spring rate and rubber compound exactly, ensuring long-term performance.
Engineered for durability, the 803190341 Hose Clamp has a corrosion-resistant zinc plating that exceeds 96 hours of salt spray testing. The rubber insert is oil-resistant and operates reliably from -40°C to +120°C. The clamp’s open design allows for quick installation and removal without disconnecting the hose. Each clamp is tested for spring force and rubber adhesion before packaging. Using OEM hose clamps prevents loose hoses that can lead to leaks and costly downtime.

Aftermarket hose clamps often use plain steel that rusts quickly or low-grade rubber that hardens and cracks. The genuine 803190341 Hose Clamp from XCMG features a durable zinc plating and EPDM rubber that resists oil and ozone. Independent tests show that OEM clamps maintain 95% of original clamping force after 10,000 hours of vibration, while generic clamps lose up to 40% of their tension. This reliability prevents hoses from loosening and leaking.
Each 803190341 Hose Clamp is 100% inspected for spring force and rubber adhesion. The clamp body is stamped with the XCMG logo and the date code for traceability. XCMG’s quality system includes salt spray testing per ASTM B117 on every batch to verify plating thickness. Using genuine clamps ensures that hoses stay securely attached, reducing the risk of fluid loss and machine downtime.
Installing the 803190341 Hose Clamp is straightforward. Position the clamp around the hose and align the mounting tab with the bracket hole. Use an M8 bolt with a flat washer and torque to 12 Nm. Do not overtighten, as this can distort the clamp body. The rubber cushion should contact the hose evenly. For best results, install the clamp within 50mm of the hose fitting to minimize unsupported length.
Inspect the 803190341 Hose Clamp every 500 hours for signs of corrosion or rubber cracking. If the rubber insert shows hardening or the clamp body has rust, replace the clamp immediately. When replacing hoses, always install new clamps to ensure proper tension. Keep a supply of these clamps in your parts inventory, as they are often lost or damaged during maintenance. Lubricate the bolt threads with anti-seize to prevent galling in corrosive environments.
A loose hose clamp allows hoses to vibrate and chafe against sharp edges, leading to pinhole leaks and sudden bursts. The genuine 803190341 Hose Clamp maintains constant tension, keeping hoses secure even under extreme vibration. Operators report that using OEM clamps reduces hydraulic oil top-ups by 60% and eliminates annoying weepage from fittings. The rubber cushion also prevents the clamp from cutting into the hose cover.
In a fleet study of 30 XCMG GR215 graders, those equipped with genuine 803190341 Hose Clamps had 80% fewer hose-related failures over 4,000 hours compared to machines using generic clamps. The consistent clamping force also prevents hoses from shifting, which protects wiring harnesses and adjacent components. For contractors who demand maximum uptime, OEM hose clamps are a small investment with significant returns.
XCMG’s stamping facility uses progressive dies to produce the 803190341 Hose Clamp body from 2.5mm thick steel coil. The spring geometry is optimized through finite element analysis to provide uniform clamping force across the diameter range. The rubber cushion is molded directly onto the clamp body using a vulcanization process that ensures a permanent bond. After assembly, each clamp is tested for spring deflection and rubber hardness.
All 803190341 Hose Clamps are packed in anti-static plastic bags in quantities of 10 or 50 per box. Bulk orders of 100 or more are palletized with desiccant. XCMG’s global distribution centers maintain stock of this fast-moving part, with same-day shipping available for urgent orders. For large fleet customers, blanket orders with scheduled releases can be arranged via the contact buttons above.
The 803190341 Hose Clamp directly replaces original part numbers 803190340 and 803190342. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders. This clamp is used on hydraulic oil cooler lines, brake hoses, and coolant hoses throughout the machine. For smaller hoses (13-19mm), use part 803190339; for larger hoses (38-45mm), use part 803190343.
When ordering the 803190341 Hose Clamp, consider purchasing the mounting bolt kit (part 803190344) which includes M8x25 flange bolts and serrated washers. XCMG recommends replacing all clamps whenever hoses are replaced, as rubber cushion hardening is not always visible. Keep a minimum of 10 clamps in your service truck to cover emergency repairs. For graders operating in coastal or high-humidity areas, stainless steel clamps (part 803190345) are available as a special order.
For custom clamp diameters or alternative rubber compounds (e.g., FKM for high-temperature applications), use the buttons above to contact our engineering support team. Always provide your grader’s serial number and a photo of the original clamp location when ordering the 803190341 Hose Clamp to ensure correct fitment.
