270950 271121 O-Ring Set, Cylinder Sleeve for Volvo D12 D13 Diesel Engine

Product Descriptions

The quality of o ring seal is vital to the performance of an engine as the sealing rings fitted to wet cylinder liners can effectively prevent the leakage of coolant into the crankcase, prevent lubricating oil entering the coolant circuit and at the same time avoid distortion of the cylinder liner.

Function of O Ring Sealing

The primary function of an O-ring is to create a secure and leak-proof seal between two mating surfaces. This small, but powerful component is commonly used in hydraulic and pneumatic systems, gasoline and diesel engines, industrial machinery and much more. O-rings serve as a barrier against fluid or gas leakage and are crucial for maintaining system integrity and performance.

Product Features:
1, Premium Quality Materials: Our O-rings are made from the highest quality materials to ensure exceptional durability, long service life and reliable sealing performance. The commonly used materials include Silicone, Viton, EPDM, NBR, HNBR, KFM, SBR, etc.
2, High Temperature Resistance: Our O-rings are engineered to withstand extreme temperatures, making them suitable for both high and low-temperature applications. This feature ensures optimal sealing performance even in the harshest operating environments.
3, Chemical Resistance: Our O-rings possess excellent resistance to a wide range of chemicals such as oils, fuels, solvents,
acids, and more.
4, Wide Application Available: Our O-ring is designed to fit various applications and numerous heavy industries.
5. Excellent Compression and Elasticity: Our O-ring is engineered with exceptional compression and elasticity properties.This allows it to maintain a reliable seal despite variations in pressure, ensuring long-term performance and reliability of the sealed system.
