|---|---|---|---|
These multi-color O-rings are general-purpose elastic sealing components included in the full overhaul gasket set for CAT 3412 V12 diesel engine. They are widely installed on cylinder liner grooves, injector sleeves, oil gallery plugs, water pipe connectors, hydraulic valve blocks and various threaded fittings.
They are essential consumables for the maintenance of CAT 3412 marine propulsion engines, large diesel generator sets and stationary industrial power equipment. Hardened, cracked or permanently deformed O-rings will cause oil seepage, coolant leakage, pressure drop and engine abnormal faults. It is standard practice to replace all O-rings during full engine disassembly and overhaul.
We supply parts for Kubota, Cum mins, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, Volv o, Deutz, Doosan, Daewoo, John De ere, Scania, Hyundai, JCB etc.
What is the difference between different colored O-rings?
Different colors correspond to different dimensions, hardness or medium resistance (coolant, engine oil, fuel), marked for quick assembly classification.
Why choose fluorine rubber O-rings instead of ordinary nitrile rubber?
FKM fluorine rubber can withstand continuous high temperature above 200°C, anti-aging and anti-swelling in diesel and lubricating oil, far more durable for heavy-duty diesel engines.
Can old O-rings be reused after disassembly?
Not recommended. O-rings lose rebound elasticity after compression; always install brand-new ones during overhaul to eliminate hidden leakage risks.
Where are these O-rings mainly installed on the 3412 engine?
Cylinder liner sealing, fuel injector seals, cooling water circuit joints, hydraulic system ports, sensor threads and cover plate mounting grooves.
