The genuine XCMG U-Clamp with OEM number 381300736 is a heavy-duty mounting component designed for motor grader pipe and hose securement.
This 381300736 U-clamp provides vibration-resistant fastening for hydraulic tubes, fuel lines, and wiring harnesses on XCMG GR series graders.
Manufactured from high-strength carbon steel with a corrosion-resistant coating, it ensures reliable clamping force even in extreme off-road conditions.
Engineered as a direct OEM replacement, the 381300736 U-clamp fits XCMG GR135, GR165, GR180, GR2003, GR215 and GR300 motor graders.
Its U-shaped geometry and integrated nut plate allow quick installation without additional washers.
Each clamp is zinc-plated and subjected to 100% salt spray testing, guaranteeing long-term durability against rust and chemicals.
By choosing genuine XCMG part 381300736, you eliminate loose fasteners, prevent hose chafing, and reduce maintenance intervals.
The clamp’s rounded edges protect rubber hoses from abrasion, while the thread-locking design resists loosening under continuous machine vibration.

• High-strength thread – class 8.8 grade, resistant to stripping.
• 100% magnetic particle inspected – ensures no hidden cracks.
Applications & System Compatibility
The 381300736 U-clamp is extensively used on XCMG motor graders for securing brake tubing, hydraulic pilot lines, fuel return hoses, and electrical conduit.
It is commonly found on the rear chassis, under the cab floor, and along the front frame where pipes are routed near moving components.
The clamp is compatible with both steel and nylon tubing.
Typical applications include heavy construction, mining haul roads, landfill compaction, and agricultural grading.
The 381300736 clamp is also suitable for use on stationary industrial equipment such as pump skids and power packs that use XCMG-style mounting standards.
Rigorous Quality Assurance & Testing
Each 381300736 U-clamp is manufactured in an IATF 16949 certified facility.
Tests include: vibration endurance (10–500 Hz, 2g acceleration, 48 hours), corrosion resistance (ASTM B117, 480 hours no red rust), and tensile pull-out test (minimum 5000 N).
The clamp also undergoes thermal cycling from -40°C to +150°C for 200 cycles without loss of clamping force.
XCMG guarantees that every 381300736 U-clamp delivers reliable service for over 10,000 operating hours under normal grading conditions.
Traceability codes are stamped on each clamp for full batch recall and quality tracking.
Installation & Maintenance Best Practices
Before installing the 381300736 U-clamp, clean the pipe or hose surface and the mounting bracket.
Place the U-bolt around the pipe, insert the ends through the bracket holes, and fit the saddle plate (if included).
Tighten the nuts evenly in a cross pattern to 25–30 Nm using a torque wrench.
Do not overtighten, as this may deform the pipe.
Inspect clamps every 500 operating hours for signs of corrosion, loose nuts, or pipe movement.
Replace any clamp that shows thread damage or rust penetration.
Always use genuine XCMG replacement nuts to maintain proper locking torque.
Environmental Sustainability
XCMG is dedicated to eco-friendly manufacturing. The 381300736 U-clamp is produced from recycled steel and finished with trivalent chromium zinc plating (Cr3+), which is less toxic than hexavalent chromium.
The manufacturing process recycles 97% of water and metal waste. At end-of-life, the clamp is 100% recyclable as ferrous scrap.
By choosing genuine XCMG clamps, you reduce waste from frequent replacements of inferior products, contributing to a more sustainable construction equipment industry.
Why Choose Genuine XCMG U-Clamp 381300736?
Aftermarket U-clamps often use low-grade steel with inconsistent bend radii that can crack or deform under vibration.
Genuine 381300736 guarantees precise geometry, certified material strength, and proven corrosion resistance.
Every authentic XCMG clamp is stamped with the OEM number and the XCMG logo for easy identification.
With XCMG’s global parts network, the 381300736 U-clamp is available for fast delivery to any job site.
