• Optimized U-bend geometry – distributes clamping force evenly without crushing tubes.
• Integrated saddle plate – prevents rotation during tightening, saving assembly time.
• High-strength thread – class 8.8 grade, resistant to stripping.
• 100% magnetic particle inspected – ensures no hidden cracks.

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.

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.

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.

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.

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. Protect your grader’s fluid lines and electrical systems by insisting on authentic XCMG components.

In summary, the XCMG U-Clamp OEM 381300736 is the definitive fastening solution for GR series motor graders. Its robust U-bolt design, corrosion-resistant coating, and precision forming ensure secure pipe and hose retention in the harshest environments. Maintenance teams can rely on the 381300736 to reduce downtime, prevent leaks, and extend component life. Upgrade your parts inventory with the original XCMG 381300736 – the clamp that keeps your grader running reliably.
