Is the performance of metric hose fittings affected in high or low temperature environments?

The performance of metric hose fittings in different temperature environments is an important issue for many industries. Whether in high or low temperature environments, the stability, sealing and durability of hose fittings will be affected to a certain extent. Therefore, understanding the impact of temperature changes on hose fittings and taking corresponding measures to optimize them is the key to ensure their normal operation in various environments.
In high temperature environments, the materials of metric hose fittings may undergo thermal expansion, resulting in slight changes in size. If the connection between the fitting and the hose is tight, high temperature may cause excessive expansion of the material, resulting in increased stress at the connection and even affecting the sealing performance. In addition, high temperature may accelerate the aging of certain materials, causing cracks or deformation on the surface, thereby affecting overall durability. If the material of the hose fitting is not properly selected, the seal ring may harden and the rubber parts may become brittle when exposed to high temperature for a long time, resulting in an increased risk of leakage.
In low temperature environments, metric hose fittings may affect the firmness of the connection due to material shrinkage. If the hose fitting is made of metal, low temperature may cause the metal to shrink, reducing the bonding force between the hose and the fitting, thereby increasing the possibility of leakage. In addition, some non-metallic materials may become brittle in low temperature environments, reducing their impact resistance and making hose fittings more susceptible to breakage or damage when subjected to external pressure. For hose fittings that need to be frequently disassembled and installed, low temperatures may increase the difficulty of operation, because the hardening of the material may make the connection parts difficult to adjust, and may even cause some parts to break due to excessive force.
In order to ensure the stability of metric hose fittings in high and low temperature environments, it is usually necessary to select appropriate materials and sealing methods according to specific application scenarios. In high temperature environments, metal alloys or special coatings with good high temperature resistance should be selected to reduce the impact of thermal expansion on the fittings, while ensuring the heat resistance of the sealing material. In low temperature environments, materials with strong cold resistance can be used to reduce embrittlement and decreased sealing performance caused by low temperatures. In addition, during installation and maintenance, regular inspection of the sealing rings and connection parts of the hose fittings and timely replacement of damaged parts can also effectively improve their stability and service life under temperature changes.
