OEM 803089171 The XCMG Fitting 803089171 is a genuine hydraulic fitting that connects a hose or tube to a port on XCMG excavators and keeps the joint sealed.
Issued under the official part number 803089171, the fitting gives technicians a correctly threaded and correctly sized connection for the component it serves.
The body is machined from steel bar, then threaded and finished so the hex takes a standard spanner or socket.
Thread type, thread size, seat angle and overall length follow the XCMG drawing, so the fitting seals at the designed torque.
A protective plating resists corrosion, which keeps the thread free and stops rust bleed around the joint.
Every fitting is checked for thread gauge, seat angle, dimensions and surface finish before the batch is packed for shipment.
Used on hose assemblies, tube lines, valve blocks and pump ports, this fitting keeps the hydraulic circuit sealed under pressure.
The 803089171 fitting is machined to the XCMG drawing, so thread type, size and seat angle match the port it threads into.
Threads are rolled or cut to the OEM class, so the fitting starts by hand and pulls down without galling or cross threading.
A correctly machined seat compresses the seal evenly, so the joint holds pressure without weeping at the threads.
The hex is sized for standard spanners, so installation and removal stay quick with ordinary workshop tools.
Solid steel construction takes full torque without distorting, so the fitting stays tight through pressure pulses and vibration.
A protective plating resists rust, so the thread stays free and the fitting comes out easily at the next service.
Because the part matches the OEM number, a technician installs it straight from the bag without adapters or re-threading.
A sound fitting keeps the hose or tube aligned with its component, which prevents side load on the hose and extends its life.
Production starts with certified steel bar, checked for grade, diameter and surface condition before machining begins.
Blanks are turned and threaded on CNC machines, so the thread and seat run concentric with the axis of the fitting.
Threads are checked with go and no-go gauges, and the seat angle is verified, so the fitting seals at the designed torque.
Inspectors measure thread size, length, hex size and seat angle on a gauge built for this exact part number.
Batch records trace every 803089171 fitting to its steel lot and machining run, so a quality question is settled quickly.
A fitting joins a hose or tube to a port, so oil can flow between components without escaping at the connection.
A loose or damaged fitting lets oil seep out and air or grit creep in, which causes pressure loss and pump wear.
The genuine 803089171 seals at its seat, so the joint holds rated pressure and the circuit stays clean and stable.
Correct thread engagement avoids stripping the port, which protects an expensive manifold, valve body or pump housing.
A sound fitting protects hoses and components, which keeps maintenance intervals predictable and extends circuit life.
The 803089171 fitting is fitted with a torque wrench and a spanner set during hydraulic hose or tube service.
Release system pressure, drain the affected line and clean the area so no dirt enters the circuit during the repair.
Check the port thread and seat for damage, then wipe the joint clean and confirm no old seal or thread debris remains.
Lubricate the seal with clean oil, thread the fitting in by hand and confirm it turns freely before applying torque.
Hold the mating half with a second spanner and tighten to the torque in the service data, so the hose is not twisted.
Refill with the specified oil, run the machine slowly and check the fitting for weeping after the first pressure cycles.
At service intervals, look for oil film, chafing or a loose connection and renew the fitting before the leak grows.
Every 803089171 fitting is produced in an ISO 9001 and ISO 14001 certified plant with traceability from bar to carton.
Incoming steel is checked for grade, and finished fittings are gauged for thread size, seat angle, length and hex size.
Each batch is inspected for cracks, burrs and damaged threads, since these defects cause leaks at the joint.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG port fixture.
Sample fittings from each batch undergo pressure and salt spray tests to confirm sealing and corrosion performance.
Cheap copies often have rough or undersized threads, so they wobble in the port and leak even after tightening.
A fitting with the wrong seat angle cannot seal against the port, and a soft body can deform or crack under pressure.
The genuine 803089171 is machined to the XCMG drawing, so thread, seat, length and plating match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM circuits.
Backed by XCMG global quality standards and technical support, this fitting performs reliably in harsh conditions.
Choosing the genuine 803089171 fitting prevents a small leak from turning into a stripped port or a damaged pump.
A leaking joint can drain a circuit slowly, which starves pumps and cylinders and shortens their service life.
A plated, correctly threaded fitting comes out cleanly at the next service, so the port thread is protected for reuse.
Reliable connections also extend hose and component life, which lowers the total cost of ownership for fleet operators.
Service records from construction and mining fleets show genuine XCMG hydraulic parts cut unplanned downtime.
XCMG produces the 803089171 fitting with efficient machining runs and tight material control that keep production scrap low.
A long service life means fewer replacements, which reduces the steel and energy tied to each fitting.
Stopping oil seepage protects soil and groundwater, helping operators meet rules on environmentally sensitive sites.
The steel in this part complies with RoHS and REACH requirements for safe handling and responsible recycling.
The 803089171 fitting is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each fitting is bagged to protect the thread and seat, then boxed in a strong carton that guards against damp and impact.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps threads clean and seats undamaged until fitting, avoiding the problems seen in loose storage.
