The genuine XCMG 803300795 Ferrule φ45 is a precision hydraulic tube collar for high‑pressure lines.
This OEM 803300795 ferrule, also called a cutting ring or sleeve, is used in flareless tube fittings.
It bites into the tube’s outer surface, creating a robust metal‑to‑metal seal that withstands up to 42 MPa (6,000 psi).
Manufactured from case‑hardened carbon steel with zinc‑nickel plating, the XCMG ferrule resists corrosion and vibration.
The φ45 designation refers to the tube outside diameter of 45 mm. It fits XCMG GR135 through GR350 motor graders.
This ferrule is a direct replacement for worn or deformed collars in steering, brake, and implement hydraulic circuits.
When the fitting nut is tightened, the ferrule compresses and grips the tube, preventing pull‑out and sealing against pressure.
A damaged or missing ferrule causes hydraulic fluid leaks, loss of system pressure, and potential safety hazards.
Replacing a faulty ferrule with genuine XCMG 803300795 restores original tube retention and eliminates weeping joints.
This ferrule is used in hydraulic cylinder supply lines, steering orbitrol connections, and brake valve ports.
XCMG 803300795 guarantees correct hardness, precise cutting edge geometry, and long‑term sealing performance.

The 803300795 ferrule is the essential sealing and gripping element in flareless hydraulic tube fittings.
When the fitting nut is torqued, the ferrule’s cutting edge bites into the tube’s outer surface permanently.
This metal‑to‑metal seal withstands high pressures, impulse spikes, and vibration without leaking or loosening.
A deformed or missing ferrule allows the tube to pull out, causing sudden oil loss and machine shutdown.
Replacing a worn ferrule with genuine XCMG 803300795 restores original clamping force and leak‑free operation.
This ferrule is commonly found in main pump delivery lines, steering valve connections, and brake tube assemblies.
Each 803300795 ferrule is machined from high‑carbon steel (C45E) and then case‑hardened for a hard cutting edge.
The carburizing process creates a surface hardness of 58‑62 HRC to a depth of 0.3‑0.5 mm.
The ferrule then receives zinc‑nickel plating, providing excellent corrosion resistance (480h salt spray).
XCMG inspects every ferrule for hardness, concentricity, and cutting edge geometry using optical measurement.
A sample from each batch is assembled with a tube and nut, then pressure‑tested to verify sealing performance.
To replace a leaking ferrule, relieve hydraulic pressure and disconnect the tube fitting.
Remove the old ferrule and discard it – never reuse a ferrule under any circumstances.
Inspect the tube for deep scratches or ovality. Cut off the damaged section if necessary and deburr the end.
Slide the fitting nut onto the tube, then the new 803300795 ferrule. Insert the tube fully into the fitting body.
Tighten the nut finger‑tight first, then torque to 120 Nm for the initial bite, loosen and retorque to 80 Nm.
After assembly, pressurize the system and check for leaks. Replace the ferrule again if leakage occurs.
Always keep spare ferrules in your parts kit – they are single‑use and cannot be reused safely.
Visible hydraulic fluid weeping from the fitting, loose nut even after tightening, and tube rotating inside the fitting.
Also, ferrule cracked or split, or the nut was overtightened causing excessive deformation of the cutting edge.
If any of these symptoms occur, replace immediately with genuine XCMG 803300795.
Inspect tube fittings for leaks during every hydraulic system check (every 500 operating hours).
Tighten any loose nuts, but do not overtighten – follow the specified torque values.
Ferrules generally last the life of the tube assembly unless the joint has been disassembled.
Whenever a fitting is opened, always install a new 803300795 ferrule to ensure a reliable seal.
In high‑vibration areas (near pumps and cylinders), check ferrule condition more frequently.
If the tube shows deep groove marks from a mis‑seated ferrule, replace both the tube and the ferrule.
Genuine XCMG 803300795 ferrules are backed by a 12‑month warranty against manufacturing defects.
Regional distribution centers: Houston (USA), Rotterdam (Netherlands), Dubai (UAE), and Shanghai (China).
Standard air freight delivers within 3‑7 business days worldwide. Emergency 24‑48 hour shipping available.
Bulk orders (50+ ferrules) receive volume discounts and sea freight options for large fleets.
Aftermarket ferrules often use mild steel and lack proper hardness, leading to early failure and leaks.
Genuine XCMG 803300795 ensures correct material, precise cutting edge, and reliable sealing under extreme pressure.
Don’t risk a hydraulic hose blowing off – a failed ferrule can cause high‑pressure oil spray and injury.
Keep spare ferrules in your service truck for quick field repairs and minimal downtime.
