OEM 804414716 The XCMG O-ring 804414716 is a genuine 365 mm by 5.3 mm sealing ring that closes the gap between large mating faces on XCMG hydraulic excavators.
Issued under the official part number 804414716, the ring gives the technician a correctly sized seal that matches the groove diameter, section height and working pressure it is designed for.
The 365 mm inside diameter and 5.3 mm cross section are molded to the XCMG drawing, so the ring sits in the groove without stretching, twisting or pinching.
A round, uniform section loads evenly around the whole circumference, so the seal holds oil and coolant without weeping at any point.
The compound is chosen for hydraulic duty, so the ring resists oil, water and heat and keeps its elasticity through long service.
Every piece is checked for inside diameter, cross section, roundness and surface finish before the batch is packed for shipment.
Fitted to large flanges, cylinder heads, covers and tank joints, this O-ring keeps fluid inside and contamination outside the cavity.
The 804414716 O-ring is produced to the XCMG drawing, so the 365 mm inside diameter and 5.3 mm section fit the groove on the first attempt.
A round, uniform section loads evenly around the whole circumference, so the ring holds oil and coolant without weeping at any point.
The compound resists oil, water and wash chemicals, so the ring does not swell, soften or crack over long service hours.
A smooth molded surface lets the ring slide into the large groove without snagging, so the section is not nicked during installation.
Because the part matches the OEM number, a fitter installs it straight from the bag without trimming or adding sealant.
Correct compound hardness keeps the ring seated under pressure cycling, so it does not extrude through the clearance gap.
A sound ring also stops fluid loss and air ingress, which protects pumps, valves and cylinders from costly internal damage.
Keeping spare rings on the shelf shortens repair time, so a weeping flange does not turn into a full day of lost production.
Each lot begins with certified rubber compound tested for hardness, tensile strength, compression set and oil resistance before molding.
Rings are compression molded in polished tooling, so the section, inside diameter and roundness stay uniform from batch to batch.
Deflashing removes flash from the sealing surface, so the ring seats cleanly and does not leak at the parting line.
Inspectors measure inside diameter, cross section, roundness and surface finish against a gauge for this exact part number.
Batch records trace every 804414716 ring to its compound lot and production run, so a quality question is settled quickly.
An O-ring sits in a groove and is squeezed between two faces, so it closes the gap and stops fluid from passing through.
A worn or cut ring lets oil weep past the joint and lets dust enter, which causes wear, leaks and unexpected failure.
The genuine 804414716 keeps the joint sealed, so pressure holds and internal parts stay protected from the environment.
Correct size avoids both a ring that rolls out of the groove and one that is pinched and cut as the parts are tightened.
A sound ring protects flanges, covers and hydraulic circuits, which keeps service intervals predictable and extends machine life.
The 804414716 O-ring is installed with a cleaning cloth, a seal pick and assembly grease during assembly or hydraulic service work.
Release system pressure, drain the affected cavity and clean the groove so no dirt or metal chips enter during the repair.
Check the groove and mating face for burrs, rust or old seal residue, since a rough surface will damage the new ring.
Coat the ring with clean assembly grease, then seat it in the groove without twisting, stretching or rolling the section.
Close the joint and tighten to the torque in the service data, so the ring compresses evenly without being cut by the gap.
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, a hardened ring or a cut section and renew the part before contamination spreads.
Every 804414716 ring is produced in an ISO 9001 and ISO 14001 certified plant with traceability from compound to carton.
Incoming compound is tested for hardness and oil resistance, and finished rings are gauged for inside diameter and cross section.
Each batch is screened for voids, cuts and flash, since these defects cause leaks or let the ring fail under pressure.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG groove fixture.
Sample rings from each batch undergo pressure, heat ageing and oil immersion tests to confirm sealing and compression performance.
Cheap copies often use low-grade compound that hardens or shrinks, so the ring loses squeeze and the joint starts to weep.
A ring with the wrong inside diameter or section can roll out of the groove, pinch or leave a gap at the sealing face.
The genuine 804414716 is made to the XCMG drawing, so inside diameter, section, hardness and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM grooves.
Backed by XCMG global quality standards and technical support, this O-ring performs reliably in harsh conditions.
Choosing the genuine 804414716 ring prevents a small weep from turning into a damaged pump or hydraulic component.
A failed ring lets oil escape and dust enter, which wears machined surfaces and shortens component life.
A correctly molded ring holds squeeze firmly, so it does not need repeated replacement and does not leak between services.
Reliable rings 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 804414716 ring with efficient molding runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each ring.
Sealing large flanges and covers 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 804414716 ring is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each ring is bagged flat to protect the section and boxed in a strong carton that guards against dust, damp and crushing.
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 large ring round and the sealing surface undamaged until fitting, avoiding distortion seen in loose storage.
