Genuine XCMG Hose Clamp with OEM number 803190403 is a precision-engineered fastening component designed for motor grader hydraulic and cooling systems. This essential clamp, 803190403, securely holds hoses and tubes in place, preventing chafing, vibration damage, and fluid leaks. Manufactured from zinc-plated spring steel with a rubber-lined inner surface, it withstands extreme temperatures, corrosion, and constant machine vibration.
Engineered for XCMG GR215, GR300, GR350, and GR2405 motor graders, the 803190403 hose clamp is used to bundle hydraulic lines, fuel hoses, and coolant pipes. Its one-piece design with a captive nut allows quick installation and removal without dropping hardware, saving maintenance time in tight engine compartments.
By choosing OEM 803190403, maintenance teams eliminate loose hoses, reduce abrasion-related failures, and prevent costly downtime. This genuine XCMG clamp guarantees perfect fit, uniform clamping force, and long-term reliability under the harshest construction conditions.

The XCMG 803190403 hose clamp is manufactured from high-carbon spring steel that provides consistent clamping force even after thousands of vibration cycles. The zinc-plated finish resists red rust for over 240 hours in salt spray testing, ensuring durability in road salt and humid environments.
The rubber inner lining protects hose outer covers from abrasion and distributes clamping pressure evenly, preventing localized deformation. The captive nut design eliminates loose hardware, a common cause of electrical shorts or engine damage.
Each clamp is 100% inspected for spring force and dimensional accuracy using automated test rigs. XCMG guarantees that the 803190403 maintains at least 90% of its initial clamping force after 1 million vibration cycles.
The 803190403 hose clamp is used extensively on motor graders to secure hydraulic hoses along the main frame, articulation joint, and engine compartment. It prevents hoses from rubbing against sharp edges, which can lead to premature failure and fluid leaks.
In the blade lift and circle drive circuits, this clamp organizes multiple hoses into a single bundle, reducing clutter and improving service access. For fuel and coolant lines, the rubber lining protects against chafing, even under constant engine vibration.
Using genuine 803190403 clamps eliminates the risk of loose hoses catching on moving parts, which could cause catastrophic damage and operator injury.
Before installation, ensure the mounting surface is clean and free of rust. Position the 803190403 clamp around the hose bundle, aligning the bolt hole with the threaded mounting point. Hand-tighten the M8 bolt to 8–10 Nm. Do not exceed 12 Nm to avoid crushing the hose or stripping the nut.
For multiple hoses, arrange them in parallel without crossing. Leave a small gap (2–3 mm) between hoses to allow for thermal expansion. Inspect the clamp every 500 operating hours for signs of corrosion or loss of spring tension. Replace the clamp if the rubber lining is cracked or the plating shows red rust.
When replacing hoses, always use a new clamp. Reusing a clamp can result in reduced clamping force and premature failure.
Generic hose clamps often use low-carbon steel that loses tension after a few months of vibration. The OEM 803190403 maintains consistent clamping force due to its spring steel construction and precision heat treatment.
Aftermarket clamps may lack the rubber inner lining, causing direct metal-to-hose contact that abrades the cover. The XCMG clamp’s rubber lining extends hose life by up to 300% in high-vibration applications.
Investing in genuine XCMG 803190403 reduces hose replacement frequency, prevents fluid leaks, and lowers overall maintenance costs.
Each 803190403 hose clamp is produced in XCMG’s ISO 9001:2015 certified facility. Random samples undergo salt spray testing, spring force measurement, and vibration endurance tests (1 million cycles at 30 Hz).
Full traceability from steel coil to finished clamp allows quality audits. XCMG provides a 12-month warranty against manufacturing defects. Rejection rate for non-conforming parts is below 0.1%.
OEM 803190403 replaces older part numbers 803190401 and 803190402. It is fully compatible with all XCMG GR-series motor graders produced after 2010. For larger hose diameters (25–32 mm), use 803190404; for smaller diameters (15–20 mm), use 803190405.
Order this hose clamp together with mounting bolts (803190406) and rubber liners (803190407) for complete installation. Bulk packaging (50 clamps) available for dealer workshops and fleet maintenance.
Q: Can the 803190403 clamp be used on wire-reinforced hydraulic hoses? A: Yes, the rubber lining protects even braided steel covers. Ensure the clamp diameter matches the hose OD.
Q: What is the recommended replacement interval? A: Replace every 4000 operating hours or when the rubber lining shows cracks or the spring loses tension.
Q: How to identify a genuine XCMG clamp? A: Genuine clamps have “XCMG” and “803190403” embossed on the metal band.
Q: Can the clamp be reused after removal? A: Not recommended. The spring steel may have taken a set, reducing clamping force. Always use a new clamp.
