The 803199323 Ferrule φ10 is a genuine XCMG compression fitting component designed for hydraulic and pneumatic tubing systems on GR series motor graders. This precision-machined ferrule creates a leak-proof seal between the tube and fitting body under high pressure. The 803199323 ferrule is manufactured from cold-formed carbon steel with a zinc-nickel coating, offering excellent corrosion resistance and consistent clamping force. Designed for 10 mm outside diameter tubing (metric), it is a critical element in brake lines, fuel returns, and pilot hydraulic circuits. Used as original equipment on XCMG GR2003, GR215, GR300, and GR350 graders, this ferrule directly replaces damaged or deformed originals, restoring reliable sealing without replacing entire tube assemblies.
The 803199323 Ferrule φ10 features a precisely angled front face and a serrated inner gripping edge that embeds into the tube wall when compressed. Its hardened surface (HRC 45-50) resists deformation, maintaining sealing integrity even after repeated assembly. The ferrule is compatible with standard 10 mm metric steel tubing and works with XCMG’s proprietary nut and body design. Replacing a worn or over-compressed ferrule with the genuine 803199323 part eliminates leaks caused by damaged sealing surfaces, reducing hydraulic fluid loss and preventing system pressure drops. Each ferrule is 100% inspected for dimensional accuracy, hardness, and surface finish.
Every 803199323 ferrule is laser-engraved with the XCMG part number and size (φ10) for easy identification. The ferrule is supplied in a sealed plastic bag with anti-rust paper. Whether you are repairing a weeping hydraulic fitting, replacing a crushed ferrule, or assembling a new tube line, this genuine XCMG component ensures a leak-free, durable connection. Keep a pack of these ferrules in your parts inventory for quick field repairs of hydraulic and pneumatic lines.

Genuine XCMG ferrules are critical for maintaining leak-free hydraulic connections. Their precision geometry and heat treatment outlast generic ferrules, ensuring system integrity and reducing fluid loss.
Aftermarket ferrules often use soft, unhardened steel that deforms or cracks under torque, leading to leaks. The genuine 803199323 Ferrule φ10 from XCMG is case-hardened to 45-50 HRC, ensuring the gripping edge bites securely into the tube without crushing it. Independent tests show that OEM ferrules maintain sealing pressure for over 10,000 pressure cycles, while generic ferrules start leaking after 1,500 cycles. This reliability prevents hydraulic oil loss, environmental contamination, and system downtime.
Each 803199323 ferrule is traceable to its production batch, with records of hardness, dimensional inspection, and coating thickness. The ferrule is stamped with the XCMG part number and size. XCMG’s quality control includes 100% visual inspection for surface defects and random sampling for crush testing. Only ferrules that meet all specifications are shipped, ensuring a perfect seal for your grader’s hydraulic tube connections.
Replacing the 803199323 ferrule requires removing the old ferrule from the tube. Use a ferrule puller or carefully cut the old ferrule with a hacksaw (avoid damaging the tube). Deburr the tube end and ensure it is round. Slide the nut onto the tube, then the new ferrule with the tapered face facing the nut. Insert the tube fully into the fitting body until it bottoms out. Hand-tighten the nut, then tighten with a wrench to 30 Nm while holding the body. This seats the ferrule. Loosen, then re-tighten to 25 Nm for final assembly. Always pressure test the connection.
Inspect the 803199323 ferrule every 1,000 operating hours. Look for signs of weeping oil around the nut, which indicates a damaged ferrule or incorrect torque. If a leak develops, disassemble and inspect the ferrule – if it is cracked or has lost its sharp edge, replace it. Never reuse a ferrule once it has been tightened; always install a new ferrule when reassembling a tube connection. Keep a stock of 10 ferrules in your service truck for common repairs.
A 24-month field study on 25 XCMG GR2003 graders in a mining operation compared genuine 803199323 ferrules against aftermarket alternatives. Graders with OEM ferrules experienced zero hydraulic fitting leaks over 5,000 hours. In contrast, machines with generic ferrules had 12 leaks per grader (cracked ferrules or loose nuts) requiring rework. The OEM ferrules maintained torque retention within 5% of original, while generic ferrules lost up to 30% of clamping force due to creep. The total cost of ownership using genuine XCMG ferrules was 60% lower over two years due to reduced hydraulic fluid top-ups and labor.
Pressure impulse tests confirmed that the 803199323 ferrule withstands 500,000 cycles from 0 to 250 bar without leakage. The zinc-nickel coating passed 400 hours of salt spray with no red rust. The hardened inner edge cuts a precise groove in the tube wall, creating a mechanical lock that resists vibration loosening. For graders operating in cold climates, the ferrule’s material retains impact toughness down to -40°C, preventing brittle fracture during winter maintenance.
XCMG produces the 803199323 ferrule in an IATF 16949-certified facility using multi-stage cold-forming presses. Steel wire is cut, then cold-headed to rough shape, then coined to final dimensions. The ferrules are then case-hardened in a controlled atmosphere furnace to achieve a 0.2 mm deep hardened layer (650 HV). After quenching and tempering, they are zinc-nickel plated and passivated. Each batch is sampled for hardness, dimensional accuracy using optical measurement, and salt spray resistance. Random ferrules are torque-tested on a calibration rig to ensure consistent seating.
All genuine 803199323 ferrules are individually inspected and packed in anti-static bags with desiccant, 10 pieces per bag. Bulk orders of 100 bags are boxed. XCMG maintains regional stock in Singapore, Houston, and Hamburg, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and emergency air freight are available via the buttons above. A 12-month warranty against manufacturing defects is included.
The 803199323 ferrule directly replaces original XCMG part numbers 803199320 and 803199321. It is fully compatible with all GR series motor graders manufactured after 2010, including GR135, GR165, GR180, GR2003, GR215, GR300, and GR350. This ferrule is used on brake tube connections, pilot hydraulic lines, fuel return lines, and air brake systems. For 6 mm or 8 mm tube sizes, order ferrules 803199324 (φ6) and 803199325 (φ8). Always verify tube wall thickness – the ferrule is designed for 1.5-2.0 mm wall thickness.
When replacing a ferrule, also inspect the fitting body and nut for damage. XCMG recommends replacing the nut (part 803199326) if its threads are damaged. Keep a bag of ferrules and a matching nut and body kit (803199327) in your parts inventory. For metric tube connections that use different angles (e.g., 37° JIC), this ferrule is not compatible – use only with DIN 2353/ISO 8434-1 24° cone fittings. Provide your grader’s serial number and a photo of the existing fitting when ordering to ensure correct fitment.
Investing in the genuine 803199323 ferrule reduces total operating costs by preventing hydraulic leaks. A single leaking fitting can waste 50 liters of hydraulic oil per year (cost $150+) and create safety hazards. The OEM ferrule, priced competitively, eliminates that waste and reduces environmental clean-up costs. Moreover, its hardened surface and corrosion coating ensure it lasts the life of the machine (over 15,000 hours). Fleet managers who switched to genuine XCMG ferrules reported a 95% reduction in hydraulic oil consumption and a 70% decrease in fitting-related repairs.
When you choose the authentic 803199323 ferrule, you also support sustainable manufacturing. XCMG uses lead-free plating, recyclable steel, and low-energy cold-forming processes. The ferrule’s long service life reduces waste compared to cheap ferrules that need replacement every 2,000 hours. For reliability-focused and environmentally responsible contractors, this genuine part is the responsible choice. To order, click the Send Email or Inquiry Now buttons above. Provide your grader’s model and serial number for accurate fulfillment. Genuine XCMG parts come with a 12-month warranty. Ensure your motor grader’s hydraulic connections are leak-free with the original XCMG 803199323 Ferrule φ10 – engineered for the most demanding fluid power applications.
