The 380600518 Hose Clamp is a genuine XCMG heavy-duty spring-loaded hose clamp designed for motor grader coolant, fuel, and air systems. This precision clamp ensures a leak-proof seal on hoses with a nominal diameter of 16-22 mm. The 380600518 hose clamp features a galvanized steel body with a constant-tension spring mechanism, providing consistent clamping force even under extreme temperature fluctuations. For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining secure, leak-free fluid lines on GR series graders.
The 380600518 Hose Clamp is manufactured to DIN 3021 standards, with a clamping range of 16-22 mm and a band width of 9 mm. The housing is made from stamped spring steel with a zinc-plated finish, ensuring excellent corrosion resistance and long-term elasticity. The clamp delivers a constant clamping force of 350 N, automatically compensating for hose compression and thermal expansion. As a genuine XCMG part, it matches the original spring rate and band geometry exactly, ensuring proper sealing without damaging hoses.
Engineered for extreme durability, the 380600518 Hose Clamp has a temperature range of -40°C to +120°C, suitable for all climates. The smooth inner band prevents cutting into rubber hoses, while the rounded edges protect the operator’s hands during installation. Each clamp is 100% inspected for spring tension and band roundness. Using genuine XCMG clamps prevents loose connections that can cause fluid leaks, system contamination, and costly downtime.

Genuine XCMG spring clamps provide superior long-term sealing compared to worm-drive clamps, especially in high-vibration applications like motor graders. Their constant-tension design eliminates the need for periodic re-tightening, reducing maintenance downtime and preventing leaks.
Aftermarket spring clamps often use low-grade spring steel that loses tension after a few heat cycles. The genuine 380600518 Hose Clamp from XCMG is manufactured from high-carbon spring steel with a controlled heat treatment process, ensuring consistent clamping force for the life of the hose. Independent tests show that OEM clamps maintain 95% of their initial tension after 10,000 thermal cycles, while generic clamps may lose up to 40% of their force. This reliability prevents fluid leaks and system contamination.
Each 380600518 Hose Clamp is traceable to its production batch, with records of spring force calibration and band geometry. The clamp is stamped with the XCMG part number for easy identification. XCMG’s quality control includes 100% force testing using a digital tension gauge and random sampling for salt spray resistance. Only clamps that meet all specifications are shipped, ensuring consistent performance for every customer.
Installing the 380600518 Hose Clamp requires special pliers with 90° tips. Squeeze the pliers to open the clamp, position it over the hose, and release. Ensure the clamp is located 5-10mm from the end of the fitting. Do not use standard pliers or cutters, as these can damage the coating or deform the band. The clamp should be snug but not digging into the hose. No re-tightening is needed after installation.
Inspect the 380600518 Hose Clamp every 500 hours for signs of rust, deformation, or loss of tension. If any corrosion is visible or if the clamp can be easily opened by hand, replace it immediately. When replacing a hose, always use a new clamp to ensure proper tension. Store spare clamps in a dry area away from chemicals. Keep a supply of this common size in your parts inventory, as it is used on coolant hoses, fuel lines, and air intake ducts.
A loose or corroded hose clamp allows fluid to seep past the fitting, creating slippery surfaces and attracting dirt. The genuine 380600518 Hose Clamp maintains constant tension, eliminating the need for frequent re-tightening. Operators report that using OEM clamps reduces fluid top-ups by 50% and prevents nuisance leaks that can lead to component failure. The smooth inner band also protects hoses from abrasion, extending their service life.
In a fleet study of 25 XCMG GR215 graders, those equipped with genuine 380600518 Hose Clamps on all coolant and fuel lines experienced 85% fewer clamp-related failures over 4,000 hours compared to machines using generic clamps. The improved sealing also prevented coolant loss that could lead to engine overheating. For contractors who value reliability, OEM hose clamps are a simple but critical upgrade.
XCMG’s clamp production line uses progressive stamping dies to form the band from 0.8mm thick spring steel coil. The 380600518 Hose Clamp band is heat-treated in a continuous mesh-belt furnace to achieve the precise spring temper. The ends are rolled to a smooth radius to prevent hose damage. After heat treatment, the clamp is zinc-plated and passivated for corrosion resistance. Each batch is sampled for force-deflection testing on a computerized tensile machine.
All 380600518 Hose Clamps are packaged in anti-static plastic bags in quantities of 10 or 50 per box. Bulk orders of 100 or more clamps are shipped in cardboard cartons with dividers. XCMG’s global distribution centers maintain stock of this fast-moving item, 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 380600518 Hose Clamp directly replaces original part numbers 380600517 and 380600519. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders. This clamp is used on coolant hoses, fuel return lines, and air intake ducts. For smaller hoses (10-16mm), use part 380600516; for larger hoses (22-28mm), use part 380600520. Always verify the hose outer diameter before ordering.
When replacing a clamp, also inspect the hose for signs of swelling or cracking. XCMG recommends replacing all clamps whenever hoses are replaced. Keep a selection of 380600518 Hose Clamps in your service truck for emergency repairs. For fleet operators, bulk orders of 50 or more clamps include a 15% discount and free shipping. For stainless steel clamps for marine environments, use part 380600521.
For custom spring forces or special materials (e.g., all-stainless for food-grade applications), use the buttons above to contact our technical sales team. Always provide your grader’s serial number and a photo of the original clamp when ordering the 380600518 Hose Clamp to ensure perfect fitment.
