Applications & System Compatibility
The 380900986 hose clamp is used extensively in XCMG motor grader cooling systems, fuel return lines, hydraulic oil cooler circuits, and air intake hoses.
It provides leak-free sealing on radiator hoses, turbocharger oil drain tubes, and power steering return lines.
The clamp is compatible with EPDM, NBR, and silicone rubber hoses commonly found on GR series graders.
Typical applications include road construction, mining, forestry, and agricultural land grading.
The 380900986 clamp is also suitable for use on stationary equipment such as generator sets and hydraulic power units that share XCMG component standards.
Rigorous Quality Assurance & Testing
Each 380900986 hose clamp is manufactured under TS 16949 quality management system.
Tests include: salt spray corrosion (ASTM B117, 480 hours), thermal cycle ( -40°C to +150°C, 500 cycles ), and vibration endurance (10–2000 Hz, 12 hours).
The clamp is also subjected to torque retention test: after 100 assembly/disassembly cycles, the clamp maintains >90% of original clamping force.
XCMG guarantees that every 380900986 hose clamp delivers reliable service for at least 8,000 operating hours under normal conditions.
Traceability codes are laser etched on each component for full batch recall and quality tracking.
Installation & Maintenance Best Practices
Before installing the 380900986 clamp, ensure the hose is fully seated on the fitting.
Position the clamp band perpendicular to the hose axis, 3–5 mm from the hose end.
Tighten the screw gradually until the hose material just begins to bulge slightly around the band.
Do not overtighten; recommended torque is 3–5 Nm. After first heat cycle, re-torque the clamp.
Inspect clamps every 500 hours for signs of corrosion, deformation, or loss of tension.
Replace immediately if the band shows cracks or the screw threads are stripped.
Always keep spare genuine XCMG clamps in a dry toolbox to avoid rust.
Environmental Sustainability
XCMG is committed to green manufacturing. The 380900986 hose clamp is produced using low-carbon steel and zinc flake coating that is free of hexavalent chromium.
The manufacturing process recycles 98% of metal scrap. At end-of-life, the clamp is 100% recyclable as ferrous scrap.
By choosing genuine XCMG clamps, you reduce waste associated with frequent replacements of inferior products, contributing to a more sustainable construction industry.
Why Choose Genuine XCMG Hose Clamp 380900986?
