Cummins Rocker Arm Chamber Gasket 3630839 5373849

The function of the engine gasket is to fill the microscopic pores between the cylinder block and the cylinder head, ensuring a good seal at the joint surface, thereby guaranteeing the sealing of the combustion chamber, preventing air leakage in the cylinder and water leakage in the water jacket, and preventing the leakage of coolant and engine oil flowing from the engine block to the cylinder head. The engine operates in high temperature, high pressure, high firing rate, high power, and in various media such as lubricating oil, antifreeze, and gases. It has high requirements for the oil-water hole material. The main materials for metal rubber ring gaskets are fluororubber and silicone rubber, which can meet the requirements. Different structures of metal rubber ring gaskets can use different types of rubber. The single-layer integrated rubber ring material can use peroxide-sulfurized fluororubber, bisphenol-sulfurized fluororubber, and oil-resistant silicone rubber. The single-layer riveted rubber ring gasket and multi-layer sandwich rubber ring gasket oil hole materials can use bisphenol-sulfurized fluororubber or oil-resistant silicone rubber. Peroxide-sulfurized fluororubber is expensive and can be omitted. The water hole material can use ordinary silicone rubber or oil-resistant silicone rubber. Peroxide-sulfurized fluororubber is expensive and can be omitted.

In mechanical equipment, flat gaskets are commonly used to fill the gaps between components, ensuring the alignment of the parts and increasing the friction force of the fastening rods. The gaskets can also be used to compensate for uneven surfaces of the components, making the joint of the parts more secure. For certain sealing components, such as O-rings and oil seals, a suitable gasket is also necessary to ensure the sealing effect.

The gasket can also bear the load. For example, in construction, the gaskets between the supporting columns and beams can effectively distribute the supporting area and reduce the oil leakage between the beams and the supporting columns. Different gaskets can bear different loads, so when choosing the gasket, it is necessary to make the selection based on the load-bearing requirements.
