OEM 318600878 The XCMG Red Copper Gasket II 318600878 is a genuine OEM sealing gasket engineered to prevent fluid leakage in hydraulic and engine joints on XCMG excavators.
Identified by part number 318600878, this red copper gasket fits between mating surfaces and creates a pressure-tight barrier that resists oil, water and coolant.
It is manufactured from high-purity annealed copper with precise dimensions and a smooth finish that ensures uniform contact pressure across the joint.
Exact OEM inner diameter, outer diameter and thickness guarantee a direct replacement without modification, so the gasket seats correctly on the first attempt.
By sealing joints securely, this red copper gasket prevents oil loss, maintains system pressure and protects pumps, valves and cylinders from contamination.
The 318600878 Red Copper Gasket II uses high-purity annealed copper that conforms to joint surfaces and creates a tight, leak-free seal.
Its soft, ductile structure fills small surface imperfections, which reduces the need for perfect machining on mating flanges.
Exact OEM inner diameter, outer diameter and thickness allow direct replacement without modification, so the gasket seats correctly on the first attempt.
The copper material withstands extreme temperatures from -200°C to +400°C, covering cold starts and hot exhaust joints.
Excellent thermal and electrical conductivity helps dissipate heat and prevents hot spots at sealing surfaces.
Production starts with certified copper strip that is checked for purity, hardness and thickness before release to stamping.
Blanks are punched and annealed on computer-controlled lines that hold inner diameter, outer diameter and flatness to exact tolerances.
Surfaces are cleaned and oxide-free to ensure uniform contact and reliable sealing on hydraulic and engine joints.
After forming, every batch is inspected for dimensions, hardness and surface quality before it is approved for packing.
Batch records let XCMG trace each 318600878 gasket back to its raw material lots, so quality issues can be identified and corrected quickly if they arise.
A red copper gasket fills the gap between mating surfaces, preventing hydraulic oil from escaping and air or dirt from entering the system.
The 318600878 gasket maintains a pressure-tight seal at both low and high working pressures, keeping flow and pressure stable.
Stable sealing protects pumps, valves and cylinders from contamination and pressure loss, reducing the chance of premature failure.
By preventing oil leakage, the gasket also keeps the machine clean and reduces fluid consumption and environmental impact.
When joints are sealed correctly, the hydraulic system responds faster and cycle times stay short, improving productivity.
Inspect the gasket regularly for hardening, cracking or deformation, and replace any worn unit promptly with a genuine 318600878 red copper gasket.
The 318600878 Red Copper Gasket II installs with standard hand tools, which keeps downtime and labour costs low during scheduled servicing.
Park the excavator on firm level ground, lower the attachment, and release all hydraulic pressure. Lock out the machine before any work begins.
Clean the mating surfaces thoroughly, remove the old gasket, and inspect the joint faces for wear, damage or contamination.
Fit the new gasket into position, ensuring it sits flat and covers the full sealing area without gaps or folds.
Assemble the joint, tighten the bolts to the specified torque, and check that the gasket is not pinched or displaced.
Start the engine at low idle, check for leaks, and run through full function cycles before returning the machine to work.
Choosing the genuine 318600878 Red Copper Gasket II pays back over time by preventing oil leaks and reducing unplanned downtime.
A failed gasket can allow hydraulic oil to escape, causing pressure loss, contamination and costly damage to pumps, valves and cylinders.
The durable construction of this gasket keeps sealing performance consistent across a long service life, reducing repair and replacement frequency.
Reliable sealing also extends the life of connected components such as hoses, tubes, valves and hydraulic motors.
Field data from large construction and mining fleets shows genuine XCMG sealing components cut hydraulic-related downtime significantly.
The gasket remains serviceable for years under normal operating conditions, removing the need for premature replacement and reducing parts inventory costs.
XCMG applies sustainable manufacturing principles to the 318600878 gasket through recyclable copper content and energy-efficient processes.
The extended service life, often exceeding 10,000 hours in normal conditions, cuts material waste and lowers the environmental footprint.
Preventing hydraulic leaks also avoids soil contamination and fluid waste, which supports regulatory compliance and responsible site stewardship.
Copper materials are free from restricted substances and comply with RoHS and REACH rules, ensuring safe handling and disposal.
Selecting genuine XCMG sealing components supports responsible equipment management while delivering superior operational reliability.
The precision-engineered design allows long, dependable service, which minimises resource consumption across the machine working life.
The 318600878 Red Copper Gasket II is held in XCMG regional distribution centres across North America, Europe, Asia and Australia.
Every unit is packed with protective wrap inside a fitted carton, shielding it from impact and moisture during transit.
For fleet-wide orders, XCMG offers volume pricing and consolidated freight options that reduce procurement costs and streamline inventory planning.
Real-time stock visibility and dedicated supply chain support help fulfil urgent requests quickly, shortening downtime and keeping excavators working.

With the XCMG global aftermarket network behind it, you can depend on consistent quality and availability to keep your fleet at full capacity.
Every 318600878 Red Copper Gasket II comes from an ISO 9001 and ISO 14001 certified plant with complete material traceability from raw copper to packed product.
Incoming copper strip is tested for purity, hardness and thickness before release to the stamping line.
During manufacturing, inner diameter, outer diameter, thickness, flatness and surface cleanliness are monitored continuously by trained operators.
Post-production checks include dimensional verification, hardness testing and pressure testing to confirm each gasket meets specification.
Sample gaskets from each batch undergo thermal cycling and pressure cycling to prove long-term durability and stable performance.
Only gaskets that clear every quality gate are released, so you receive a dependable, high-performance sealing component every time.
Cheap aftermarket gaskets often use lower-grade copper, incorrect hardness or inaccurate dimensions that lead to rapid failure.
Those shortcuts lead to oil leaks, pressure loss and poor reliability in demanding construction, mining and quarry conditions.
The genuine 318600878 is built to the exacting XCMG standards, delivering correct fit, reliable sealing and durable performance in the field.
Its precision-annealed body and high-purity copper provide consistent results, lowering the chance of expensive hydraulic failures and machine downtime.
