OEM 319002309 The XCMG Return Oil Steel Pipe 319002309 is a genuine rigid steel line that carries returning hydraulic oil back to the tank on XCMG excavators.
Issued under the official part number 319002309, the pipe gives the technician a correctly routed line that matches the port threads, brackets and clearance it is designed for.
The tube is bent and formed to the XCMG drawing, so the route clears the block, mounts and nearby harnesses without kinking or rubbing.
End fittings are machined and seated to the drawing, so the thread, flare or banjo eye matches the return filter head without adapters.
A protective coating resists oil, water and road salt, so the line keeps its surface and does not corrode through long outdoor service.
Every line is checked for bend angle, length, fitting thread and internal cleanliness before the batch is packed for shipment.
Fitted to the return circuit and filter connection, this steel pipe keeps returning oil flowing freely and keeps the circuit sealed.
The 319002309 pipe is produced to the XCMG drawing, so the bend angles and length match the engine bay without forcing or rerouting.
Correct fittings seat against the filter head and tank port, so the joint seals against return pressure and does not weep.
The steel tube resists oil, water and additives, so the line does not soften, kink or crack over long service hours.
A clean internal bore keeps return flow steady, so back pressure stays low and the oil reaches the tank freely.
Because the part matches the OEM number, a fitter installs it straight from the bag without bending, cutting or adding adapters.
Correct clip spacing keeps the line away from hot surfaces and sharp edges, so vibration does not wear through the wall.
A sound return line also stops air ingress and oil loss, which protects the pump and keeps the circuit running cool.
Keeping a spare line on the shelf shortens repair time, so a cracked pipe does not turn into a full day of lost work.
Each lot begins with certified steel tube tested for wall thickness, pressure strength and corrosion resistance before forming.
Lines are bent on CNC equipment, so the route, bend radius and fitting alignment stay uniform from batch to batch.
End fittings are machined and joined to the drawing, so the flare, thread or banjo eye seats cleanly without leaks.
Inspectors measure length, bend angle, fitting thread and internal cleanliness against a gauge for this exact part number.
Batch records trace every 319002309 line to its tube lot and production run, so a quality question is settled quickly.
A return oil steel pipe carries oil from the circuit back to the tank and filter, so the system keeps a steady supply.
A cracked or loose pipe lets air enter and oil escape, which causes overheating, foaming and unexpected shutdown.
The genuine 319002309 keeps the return path sealed, so pressure holds and the pump stays protected.
Correct routing avoids both a line that rubs through on a bracket and one that kinks and restricts return flow.
A sound line protects the filter, tank and pump, which keeps service intervals predictable and extends machine life.
The 319002309 line is installed with a cleaning cloth, a spanner set and a torque wrench during hydraulic service work.
Release system pressure, drain the affected section and clean the fittings so no dirt enters the circuit during the repair.
Check the port threads and sealing faces for damage, rust or old sealant, since a rough surface will stop the line sealing.
Route the line along the original path, fit the clips and start the fittings by hand so the thread is not cross-threaded.
Tighten to the torque value in the service data, so the joint seals without distorting the tube or cracking the nut.
Refill with the specified oil, run the machine slowly and check the joints for weeping after the first pressure cycles.
At service intervals, look for oil film, rubbed tube walls or loose clips and renew the part before a leak spreads.
Every 319002309 line is produced in an ISO 9001 and ISO 14001 certified plant with traceability from tube to carton.
Incoming tube is tested for wall thickness and pressure strength, and finished lines are gauged for length, bend and thread.
Each batch is screened for cracks, dents and thread defects, since these flaws cause leaks or let the line burst under pressure.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG engine bay fixture.
Sample lines from each batch undergo pressure, vibration and salt spray tests to confirm sealing and corrosion performance.
Cheap copies often use thin tube that kinks or cracks, so the line weeps or bursts soon after installation.
A line with the wrong bend or fitting type can rub on the block, cross-thread the port or leave the joint standing proud.
The genuine 319002309 is made to the XCMG drawing, so route, length, fitting and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM engine bays.
Backed by XCMG global quality standards and technical support, this return steel pipe performs reliably in harsh conditions.
Choosing the genuine 319002309 line prevents a small seep from turning into a damaged pump or an overheated circuit.
A failed line lets air enter and oil escape, which causes overheating, foaming and unplanned downtime.
A correctly made line seals firmly, so it does not work loose and does not need repeated tightening or replacement.
Reliable return lines also keep flow steady, 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 319002309 line with efficient bending and assembly runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each steel line.
Sealing the return circuit prevents oil leaks and contamination, which protects soil, groundwater and engine parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 319002309 line is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each line is bagged to protect the fittings and boxed in a strong carton that guards against dust, damp and bending.
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 bend shape and fitting threads undamaged until installation, avoiding the distortion seen in loose storage.
