OEM 800167213 The XCMG Thermostat Seal 800167213 is a genuine OEM coolant seal ring engineered to stop leaks at the thermostat seat on XCMG hydraulic excavators.
Identified by part number 800167213, this factory-made seal sits against the thermostat flange and seals the coolant passage under clamp load.
It is molded from heat-resistant, coolant-resistant rubber compound with accurate inside and outside diameters for a precise, squeeze-fit installation.
Exact OEM dimensions allow direct replacement without trimming, stretching, or adding sealant, keeping the repair clean and fast.
By holding compression and elasticity, this thermostat seal prevents coolant loss, air ingress, and unstable engine temperature.
The 800167213 Thermostat Seal is molded from coolant-resistant rubber that keeps its elasticity in hot glycol mixtures and under clamp load.
Accurate inside and outside diameters let the seal seat evenly in its groove, so squeeze is uniform around the thermostat flange.
Low compression set means the ring returns to shape after thermal cycles, which prevents weeping between service intervals.
A smooth, flash-free surface reduces the risk of nicks and cuts during installation, which are common causes of early seal failure.
Heat aging resistance stops the rubber from hardening or cracking, so the seal keeps working through thousands of warm-up cycles.
Exact OEM dimensions allow direct replacement without sealant or improvisation, keeping the repair clean and predictable.
Production starts with a certified rubber compound tested for hardness, tensile strength, coolant swell, and compression set before molding.
Compression molding is carried out under controlled pressure and temperature, so every ring cures fully and holds a consistent cross-section.
Flash and excess material are trimmed away, and the sealing surface is inspected so no burr can create a leak path.
Finished rings are measured for inside diameter, outside diameter, cross-section, and hardness, then checked for cuts and blisters.
Batch records let XCMG trace every 800167213 seal back to its compound lot and molding press, so quality questions are answered quickly.
The thermostat seal is a small part, but it is the barrier that keeps hot coolant inside the housing joint.
When the seal hardens or flattens, coolant seeps past the thermostat flange, pressure drops, and the engine runs hotter.
The genuine 800167213 keeps its compression and elasticity, so the joint stays tight through pressure spikes and thermal cycling.
Correct sealing also prevents air from entering the cooling circuit, which avoids air locks, erratic temperature, and heater faults.
Stopping coolant leaks protects nearby paint, wiring, and ground from contamination and keeps inspection areas clean.
The 800167213 Thermostat Seal installs with standard sockets and a seal pick, adding only minutes to a cooling system repair.
Let the engine cool completely, release cooling system pressure, and drain coolant to the level recommended in the workshop manual.
Remove the thermostat housing, take out the old thermostat, and clean the seat so old rubber residue and scale are fully removed.
Lubricate the new seal with coolant, seat it squarely in the groove, and confirm it is not twisted or pinched.
Refit the thermostat and housing, tighten bolts to the manual torque, refill coolant, and run the engine to check for leaks.
During routine maintenance, replace the seal whenever the thermostat is serviced, and never reuse a hardened or deformed ring.
Every 800167213 seal is produced in an ISO 9001 and ISO 14001 certified plant with traceability from compound to packed carton.
Incoming rubber is tested for hardness and coolant resistance, and finished seals are measured for both diameters and cross-section.
During production, molding pressure, temperature, and cure time are monitored to keep every ring within the XCMG drawing tolerance.
Post-production checks include visual inspection, hardness testing, and a trial fit in the XCMG thermostat seat fixture.
Sample seals from each batch undergo coolant soak, compression set, and heat aging tests to confirm long-term sealing performance.
Low-cost aftermarket seals often use low-grade rubber that hardens quickly, swells in coolant, or takes a permanent set.
A ring with the wrong cross-section can be pinched during assembly, which creates a leak path almost immediately.
The genuine 800167213 is molded to the XCMG drawing, so inside diameter, cross-section, hardness, and material match the original.
Using genuine XCMG parts also preserves warranty coverage, protects resale value, and maintains compatibility with other OEM components.
Backed by XCMG global quality standards and technical support, this thermostat seal delivers dependable sealing in harsh conditions.
Choosing the genuine 800167213 seal prevents a small coolant weep from turning into an expensive engine overheating repair.
A failed seal can drain the cooling system, which warps heads and damages gaskets within minutes of operation.
Durable rubber and correct compression keep sealing performance consistent across a long service life, reducing replacement frequency.
Reliable sealing also extends coolant, hose, and thermostat life, lowering the total cost of ownership for fleet operators.
Fleet records from construction and mining operations show genuine XCMG seals help cut leak-related downtime significantly.
XCMG applies sustainable manufacturing to the 800167213 seal through efficient molding and reduced material waste.
The long service life of the ring reduces material consumption and lowers the environmental footprint of replacement parts.
Preventing coolant leaks protects soil and groundwater and supports compliance on environmentally sensitive sites.
Rubber materials in this component comply with RoHS and REACH rules for safe handling and responsible disposal.
The 800167213 Thermostat Seal is held in XCMG regional distribution centres across North America, Europe, Asia, and Australia.
Each ring is bagged and packed in a sturdy carton that protects it from dust, moisture, and deformation during transport.
For fleet-wide orders, XCMG provides volume pricing and consolidated freight options that simplify planning and reduce cost.
Real-time stock visibility and dedicated supply chain support help fill urgent requests quickly, shortening downtime on active projects.
Robust packaging preserves factory condition until installation, preventing the cuts and contamination common in stored seals.
