OEM 319002855 The XCMG Fitting 319002855 is a genuine connector that links tubes, hoses and pipe runs inside the hydraulic system of XCMG excavators.
Released under the official part number 319002855, the fitting gives the service technician a correctly sized connector that matches the thread, seat and bore it was designed for.
The body is machined to the XCMG drawing, so the thread pitch, hex flats and shoulder align with the mating port without cross-threading or force.
Where the drawing calls for a sealing face, the fitting carries the correct cone, O-ring groove or bonded seal seat, so it seals and holds under working pressure.
A protective plating resists oil, water and corrosion, so the fitting keeps its thread and sealing surface through wash-down and long outdoor service.
Every unit is checked for thread gauge, bore diameter, hex dimension and surface finish before the batch is packed for shipment.
Fitted to main hydraulic lines, pilot circuits, cooling pipes and lubrication runs, this fitting keeps fluid inside and contamination outside.
The 319002855 fitting is produced to the XCMG drawing, so the thread, hex and shoulder line up with the mating port on the first attempt.
Correct sealing geometry holds hydraulic pressure and keeps dust out, so the circuit stays clean and dry during daily operation.
The steel body resists oil, water and wash chemicals, so the fitting does not corrode, seize or weep at the joint over time.
Clean machined threads let the fitting run down by hand, which reduces the risk of cross-threading and damaged port threads.
Because the part matches the OEM number, a fitter installs it straight from the bag without adapters, trimming or extra sealant.
Correct material hardness keeps the hex and thread intact under vibration, so the joint does not work loose on rough ground.
A sound connection also stops air ingress and fluid loss, which protects pumps, valves and cylinders from costly internal damage.
Keeping spare fittings on the shelf shortens repair time, so a burst hose does not turn into a full day of lost production.
Each lot begins with certified steel bar stock tested for chemistry, hardness and tensile strength before it reaches the machining line.
Parts are turned and threaded on CNC equipment, so the thread pitch, bore and hex flats stay uniform from batch to batch.
Deburring removes sharp edges from the thread ends and sealing faces, so the fitting seats cleanly and does not cut a hose or O-ring.
Inspectors measure thread gauge, bore diameter, length and surface finish against a dedicated gauge for this exact part number.
Batch records trace every 319002855 fitting to its steel lot and production run, so a quality question is settled quickly.
A fitting joins a hose or tube to a port so fluid flows between components while the joint stays sealed under pressure.
A loose or cracked fitting lets hydraulic oil escape and lets dirt enter, which causes wear, leaks and unexpected failure.
The genuine 319002855 keeps the joint tight, so pressure holds and internal parts stay protected from the environment.
Correct fit avoids both a fitting that weeps under vibration and one that cracks the port when tightened past its limit.
A sound connection protects hoses, valves and cylinders, which keeps service intervals predictable and extends machine life.
The 319002855 fitting is installed with a cleaning cloth, a spanner set and a torque wrench during assembly or hydraulic service work.
Release system pressure, drain the affected line and clean the port so no dirt or metal chips enter during the repair.
Check the port thread and sealing face for damage, rust or old sealant, since a rough surface will stop the fitting seating fully.
Lubricate the thread with clean oil where the drawing allows, then run the fitting in by hand until it contacts the seat.
Tighten to the torque value in the service data, so the fitting seals without distorting the port or cracking the body.
Refill with the specified oil, run the machine slowly and check the joint for weeping after the first pressure cycles.
At service intervals, look for oil film, loose fittings or rusted threads and renew the part before contamination spreads.
Every 319002855 fitting is produced in an ISO 9001 and ISO 14001 certified plant with traceability from steel bar to carton.
Incoming steel is tested for chemistry and hardness, and finished fittings are gauged for thread, bore and overall length.
Each batch is screened for cracks, laps and thread defects, since these flaws cause leaks or let the fitting break under pressure.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG port fixture.
Sample fittings from each batch undergo pressure, heat ageing and salt spray tests to confirm sealing and corrosion performance.
Cheap copies often use low-grade steel with soft threads, so the fitting strips, seizes or weeps soon after installation.
A fitting with the wrong thread or seat angle can cross-thread the port, crack the housing or leave the joint standing proud.
The genuine 319002855 is made to the XCMG drawing, so thread, length, seat and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM housings.
Backed by XCMG global quality standards and technical support, this fitting performs reliably in harsh conditions.
Choosing the genuine 319002855 fitting prevents a small weep from turning into a damaged pump or hydraulic component.
A failed joint lets oil escape and dust enter, which wears machined surfaces and shortens component life.
A correctly made fitting seals firmly, so it does not work loose and does not need repeated tightening or replacement.
Reliable fittings also keep pressure contained, which improves machine performance and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 319002855 fitting with efficient machining runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each fitting.
Sealing hydraulic joints prevents oil leaks and contamination, which protects soil, groundwater and internal parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 319002855 fitting is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is bagged to protect the thread and sealing face and boxed in a strong carton that guards against dust and damp.
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 the fitting round and the seat undamaged until installation, avoiding distortion seen in loose storage.
