OEM 318805284 The XCMG Fitting 318805284 is a genuine OEM hydraulic fitting that joins a hose or pipe to a port and keeps the circuit leak-free on XCMG excavators.
Marked with part number 318805284, this factory fitting gives technicians a correctly threaded, correctly angled connector that mates with the original port.
The body is machined from quality steel bar, threads are cut to drawing limits, and the sealing face is finished to hold pressure without weeping.
Exact thread size, hex across flats and installed depth let the fitting seat properly, so no adapter or extra thread sealant is needed.
A clean, tight seal stops oil from escaping under pressure, which protects flow stability and keeps the machine bay free of drips.
Every fitting is gauged and pressure tested before packing, so the part you receive matches the XCMG drawing specification exactly.
The 318805284 fitting is machined from quality steel bar, so the body resists deformation when pressure spikes travel through the line.
Threads are cut to drawing limits, so the fitting starts by hand and tightens smoothly into the original port.
The sealing face is finished flat or fitted with the correct O-ring, which closes the joint without extra tape or sealant.
Correct hex across flats lets a standard wrench reach the fitting, even in tight areas behind pumps and valve blocks.
Anti-corrosion plating protects the exterior from mud, water and salt spray, so the hex does not round off over time.
Exact installed depth keeps the flow path open, which avoids restriction and keeps function response quick.
Because the part matches the OEM connector, a technician can replace a leaking joint in minutes instead of hunting adapters.
Production starts with certified bar stock checked for grade, hardness and internal soundness before it reaches the lathe.
CNC turning holds thread pitch, hex size and sealing face geometry to drawing limits, so every fitting installs the same way.
Threads are gauge checked and sealing faces are inspected for chatter marks, which are common causes of weeping joints.
Inspectors verify thread size, hex, overall length and bore against a checking fixture built for this part number.
Batch records trace every 318805284 fitting back to its bar stock heat and machining program, so quality questions close fast.
The fitting connects a hose or pipe to a port, giving pressurized oil a sealed path from one component to the next.
A worn thread or damaged seat lets oil escape, which drops circuit pressure and slows machine response.
The genuine 318805284 seals tightly, so pressure holds where it should and the pump does not work harder than needed.
Correct thread engagement spreads load along the port, which prevents stripped threads and cracked housings.
A sound connection protects pumps, valves and cylinders, which keeps cycle times and machine uptime predictable.
The 318805284 fitting installs with a wrench set and torque wrench during scheduled hydraulic service or repair.
Relieve hydraulic pressure, stop the engine and place a drain pan under the joint before loosening anything.
Remove the old fitting, then clean the port and inspect threads and the sealing surface for burrs, rust or cracks.
Fit a new O-ring if specified, thread the fitting in by hand until it seats, then torque it to the drawing value.
Start the engine, cycle each function slowly, and check the joint and nearby connections for weeping or movement.
At service intervals, look for damp patches, oil film or corrosion around the hex and replace the fitting if a leak appears.
Never over-torque a fitting to stop a leak, because that stretches threads and can crack the port casting.
Every 318805284 fitting is produced in an ISO 9001 and ISO 14001 certified plant with traceability from bar stock to packed carton.
Incoming bar is checked for grade and hardness, and finished fittings are gauged for thread, hex, length and bore.
Each unit is pressure tested or sample tested for leakage before it is marked, capped and packed.
Final checks cover appearance, dimensions and a trial fit on the XCMG port fixture used for this machine family.
Samples from every batch go through pressure cycling, salt spray and vibration tests to prove long-term performance.
Cheap copies often cut threads undersize or finish seats poorly, so they weep within days of installation.
A fitting with the wrong thread or depth can bottom out in the port, which damages the seat and cracks the housing.
The genuine 318805284 is machined to the XCMG drawing, so thread, hex, depth and seat match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps compatibility with other OEM components.
Backed by XCMG global quality standards and technical support, this fitting performs reliably in harsh conditions.
Choosing the genuine 318805284 fitting prevents a small weep from turning into an expensive component replacement.
A failed joint can drain the reservoir fast, which starves the pump and damages internal parts within minutes.
Sound machining and correct plating keep the fitting serviceable across a long life, which reduces replacement frequency.
Reliable connections also extend hose, seal and oil life, lowering the total cost of ownership for fleet operators.
Service records from construction and mining fleets show genuine XCMG hydraulic parts cut unplanned downtime.
XCMG builds the 318805284 fitting with efficient machining programs that keep material scrap and energy use low.
A long working life means fewer replacements, which lowers the raw material and energy tied to each fitting.
Containing hydraulic leaks protects soil and groundwater, helping operators meet rules on sensitive job sites.
The steel and plating in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 318805284 fitting is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each fitting is capped, bagged and boxed in strong cartons that guard against thread damage, dust and damp in transit.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams help cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the fitting in factory condition until installation, avoiding the nicked threads seen in loose stock.
