Specification | 42*60*7/30*40*7/83*97*7 | Material Diversity | Metal Gasket with Rubber FKM |
Origin | Chengdu China | Transport Package | Packaged According to Specifications - Land Transp |
Material composition | The main body is formed by the co-vulcanization of fluororubber (FKM) and the outer framework, and it possesses excellent heat resistance (-25 to 300℃) and oil resistance. Other materials include nitrile rubber (NBR, with a temperature range of -40 to 120 degrees Celsius), silicone rubber (VMQ), acrylate rubber, etc. The choice depends on the specific working conditions. | |
Structural characteristics | The inlet part is integrated with a self-tightening spring or wire, enhancing the sealing fit. The lip design includes thick lips (resistant to high pressure) or with grooved texture (to assist the flow of engine oil back). The oil seals of the intake/exhaust valves are distinguished by color (for example, the intake valve is dark golden/green, and the exhaust valve is gray silver/red) or marked with "IN" / "EX" | |
Sealing property | Prevent the leakage of engine oil into the intake/exhaust pipes and combustion chambers, and avoid abnormal consumption of engine oil; Prevent the leakage of the gasoline-air mixture and exhaust gas, and maintain the combustion efficiency | |
Resistant to high temperature and high pressure | Long-term exposure to high-temperature engine gases (300℃) and valve movement impacts | |
Resistant to chemical corrosion | Resist the erosion caused by engine oil, gasoline and acidic combustion products | |
Sealing form | Active (pre-pressure sealing) / Passive (air pressure adaptive) | High-speed/ Turbocharged Engine |
