Products Description
Durable hose also called the double-sided adhesive high-pressure water hose is processed in three layers. The inner and outer layers of materials can be customized according to needs, and the thickness varies according to pressure requirements，the middle is polyester filament, The belt is thick, and the thickness of one side is about 2mm. More wear-resistant and low temperature resistant than ordinary water hose.
Fire durable hoses undergo rigorous testing to ensure their reliability and compliance with industry standards. These tests evaluate factors such as burst pressure, flexibility, heat resistance, and overall performance under varying conditions. Regular inspections and maintenance are necessary to identify any signs of wear, damage, or deterioration, thereby ensuring that the hoses remain in optimal working condition.
Moreover, fire durable hoses are designed to be flexible, allowing firefighters to navigate around obstacles and reach confined areas easily. They also feature standardized couplings at each end, enabling quick and secure connections to hydrants, pumps, or other firefighting equipment.
Due to its structural characteristics, durable hoses have very strong resistance and usually have a long service life. Durable hoses are very popular in the world and are widely used in many fields, such as agricultural irrigation, fire rescue, etc. Their derivative products include large diameter disposable durable hoses, commonly used in oil transportation and other scenarios.

Installation Tips
1. The nozzle shall be installed after the system pressure test and flushing are qualified.
2. The nozzle shall be installed with special elbow and tee.
3. During the installation of the nozzle, it is not allowed to disassemble or change the nozzle, and it is strictly prohibited to attach any decorative coating to the nozzle.
4. The nozzle should be installed with a professional wrench, and it is strictly prohibited to screw with the nozzle frame. If the frame of the nozzle and the splash tray are deformed or damaged, the nozzle with the same specification should be used for replacement
5.When the nominal diameter of the nozzle is less than 10mm, a filter shall be installed in the main water distribution pipe.
6. Sprinklers installed at vulnerable places shall be provided with protective covers.
