The sealing part of the Hose Fittings usually adopts specially designed sealing rings or O-rings. These sealing elements can fit tightly with the hose and pipe to effectively prevent medium leakage. At the same time, the fit between the connector body and the sleeve is also accurately calculated to ensure that good sealing performance can be maintained under harsh working conditions such as high pressure, high temperature or vibration. The sealing elements of the Hose Fittings are usually made of oil-resistant, water-resistant and corrosion-resistant polymer materials, such as nitrile rubber and fluororubber. These materials not only have good elasticity and can maintain stable sealing performance under various working conditions, but also have excellent chemical corrosion resistance and can resist erosion by a variety of media.
In some special applications, the Hose Fittings will also adopt multiple sealing structures, such as double O-ring seals, labyrinth seals, etc., to further improve the sealing performance. This multiple sealing structure can maintain a stable sealing effect and prevent medium leakage when the medium pressure fluctuates or the temperature changes.
In construction machinery, Hose Fittings are often exposed to harsh working conditions, such as high temperature, high pressure, corrosive media, etc. Hose Fittings are usually made of corrosion-resistant materials such as stainless steel and copper alloys, which can resist the erosion of various corrosive media, such as acids, alkalis, salts, etc. At the same time, the surface of the connector can also be specially treated, such as galvanizing, nickel plating, etc., to improve its corrosion resistance.
Hose Fittings are often affected by friction and wear in engineering machinery, such as pipeline vibration, medium flow, etc. Therefore, the connector material needs to have good wear resistance. Some high-quality Hose Fittings will use special alloy materials or wear-resistant coatings to improve their wear resistance. These materials can resist the erosion of wear particles and extend the service life of the connector.
In engineering machinery, Hose Fittings are often subjected to alternating stresses, such as pipeline vibration, temperature changes, etc. Therefore, the connector needs to have good fatigue resistance. Some high-quality Hose Fittings will use special heat treatment processes or alloy materials to improve their fatigue resistance. This fatigue resistance can ensure that the connector maintains stable performance during long-term use and is not prone to failures such as cracks or breaks.
