Product Description Composite gaskets: the best choice for superior sealing performance:In industrial production and equipment operation, the sealing link is crucial, and a small leak may cause serious consequences. As the industry's leading sealing solution, our composite gaskets are providing excellent performance for a wide range of applications.The composite gasket has excellent anti-aging and wear resistance. In the long-term use process, it will not be damaged by frequent pressure fluctuations, medium erosion or mechanical friction, greatly reducing the replacement frequency, reducing maintenance costs, saving a lot of manpower, material resources and time for enterprises, and becoming the ideal choice for the pursuit of efficient production.In equipment with frequent vibration or dynamic load, screws are easy to gradually loosen due to continuous vibration, which affects the normal operation of the equipment and even causes failure. With the excellent cushioning performance of its inner flexible material, the composite gasket can effectively absorb vibration energy and significantly reduce the impact force of the screw, thereby preventing the screw from loosening.Nominal diameterof screw(mm)Outer diameterof gasket(mm)Inner diameter of gasket(mm)M1.641.7M252.2M2.562.7M373.2M494.3M5105.3M6126.4M8168.4M102010.5M122413M163017M203721M244425M305631M366637 Characteristics:Sealing performance, high strength, pressure resistance, vibration resistance, impact resistance, corrosion resistance, chemical stability, high temperature resistance, low temperature resistance, low permeability, self-lubrication, elasticity, flexibilityProduct structure: composite gasket, metal layer, sealing layer, multi-layer structure, hexagonal screw matching, fastening sealPerformance parameters: working temperature range, working pressure range, hardness, friction coefficient, service life.SIZEM2.9M3.5M3.9M4.2M4.8M5.5M6.3dk6.38.38.38.810.51113.5k2.83.43.44.14.35.45.9s45.55.578810 SIZEM2.9M3.5M3.9M4.2M4.8M5.5M6.3dk6.38.38.38.810.51113.5k2.83.43.44.14.35.45.9s45.55.578810 Hexagonal screw composite gaskets are usually composed of multiple materials to meet different application requirements. Here is some information about the common materials and their performance characteristics:How to choose a hexagon screw composite gasket material suitable for a specific application scenario?The selection of hexagonal screw composite gasket material suitable for specific application scenarios needs to consider a number of factors, the following are some key points:Working environmentTemperature: If the working environment temperature is high, you can choose high temperature resistant materials, such as flexible graphite, silicone rubber, etc. In a low temperature environment, it is necessary to consider the low temperature flexibility of the material, such as polytetrafluoroethylene and some rubber materials can still maintain good performance at low temperatures. For example, in the connection of high temperature furnace, the use of flexible graphite composite gasket is more appropriate; In outdoor equipment in cold areas, the choice of low-temperature rubber or polytetrafluoroethylene composite gaskets can better ensure the sealing effect.Humidity and corrosive media: In the environment of wet or corrosive media, priority should be given to materials with good corrosion resistance. For example, the composite gasket of stainless steel metal layer with flexible graphite, polytetrafluoroethylene or neoprene sealing layer is suitable for chemical industry, electroplating and other industries. If it is in a food processing environment, in addition to corrosion resistance, it is also necessary to consider the hygiene of the material, at this time, food-grade rubber or polytetrafluoroethylene composite gaskets are more appropriate.Vibration and shock: For equipment with vibration or shock, such as engines, compressors, etc., it is necessary to choose rubber composite gaskets with good elasticity and buffer performance, which can absorb vibration energy, prevent screws from loosening, and ensure the stability of the connection.Installation space: If installation space is limited, you need to choose a thin or compact design of the composite gasket to ensure smooth installation. For example, in some precision instruments or equipment with narrow space, it is necessary to use thinner polytetrafluoroethylene composite gaskets.Maintenance requirements: Consider the replacement frequency and maintenance difficulty of gaskets. Some materials, such as rubber gaskets, may age and harden after long-term use and need to be replaced regularly; The polytetrafluoroethylene composite gasket has a long service life and low maintenance costs. For the occasions that are difficult to maintain, the gasket material with stable performance and long service life should be selected.
