1. High elasticity, good compression recovery, anti-aging, wear-resistant and corrosion-resistant, effectively prevent liquid and gas leakage of CAT 3406 engine and hydraulic components
2. Multiple material formulas for different working conditions: NBR for conventional oil resistance, red FKM for high temperature and high pressure resistance, purple silicone for coolant and high heat environment
3. Standard dimensional tolerance, smooth surface, easy installation, can be matched with engine overhaul gasket set for complete CAT engine rebuild
4. Multi-color classification design, convenient quick identification during heavy equipment maintenance, greatly improve overhaul efficiency

CAT 3406 O-ring kit is a special-purpose circular elastic sealing ring for CAT 3406 diesel engine and its supporting hydraulic system. It relies on rubber elastic deformation to fill the gap between fitting parts, block the passage of engine oil, coolant, hydraulic oil and compressed air, and solve seepage and leakage faults of engine components, hydraulic circuits and pipeline joints on CAT heavy-duty machinery.

It is a necessary auxiliary sealing accessory when disassembling and maintaining CAT 3406 engine, water pump, fuel injector, hydraulic manifold and oil circuit connectors.

We supply parts for Kubota, Cum mins, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, V olvo, Deutz, Doosan, Daewoo, John De ere, Scania, Hyundai, JCB etc.
