Cylinder Liner O-Ring Seal Kit for CAT 3304 Diesel Engine

• Applicable Engine: 3304 4-cylinder diesel engine
• Product Name: Cylinder Liner Cooling System O-Ring Seals
• Composition: Black, green and orange high-performance rubber O-rings
• Material: Heat-resistant fluorine rubber & nitrile rubber
• Function: Seal cylinder liner outer circle to prevent coolant leakage
• Condition: 100% brand new, complete size set for full engine overhaul

1. Different colored rubber materials for different temperature and pressure positions, strong resistance to coolant, aging and high temperature deformation
2. Exact inner and outer diameter matched for CAT 3304 cylinder liners, tight fit to block cooling water seepage between liner and engine block
3. Good elasticity and compression resistance, not easy to harden or crack under long-term engine working temperature
4. Complete matching set for 4 cylinders, one-time replacement during engine block disassembling and liner maintenance

These O-rings are installed on the outer groove of cylinder liners of CAT 3304 engine, forming a closed cooling water channel between cylinder liner and cylinder block. Aged, cracked or deformed O-rings will cause cooling water leakage into the crankcase, resulting in water-oil mixing, engine oil emulsification and serious engine failure. They are essential sealing accessories for cylinder liner pulling and engine major repair.

We supply parts for Kubota, Cumm ins, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, Vol vo, Deutz, Doosan, Daewoo, John De ere, Scania, Hyundai, JCB etc.

Shipping: Sea freight, air freight and international express are all available. Tax Notice: All import duties and local destination taxes shall be borne by the buyer. Please confirm engine model CAT 3304 before purchase.

Coolant leaks into crankcase, engine oil turns milky white, lubrication performance declines, leading to bearing ablation and engine locking.

Clean the O-ring grooves on cylinder block and liner thoroughly, evenly apply a small amount of coolant lubricant during installation to avoid cutting the O-ring.
