1, Feng Run, is one of the main components of radiator, and its main function is to deflate the heater. When there is air in the heating system, the radiator is not hot. Releasing it can release the air in the radiator and make the radiator circulate better. Because air and water contact with air and water, copper or chromium-plated copper alloy is generally used to prevent corrosion and ensure service life.

2. Plug, which is used at the end of the pipeline to prevent water leakage and play a sealing role. It is a common pipe fitting in the installation of water heating system, which requires strong corrosion resistance, will not be corroded by sewage and wastewater, and will not appear frost crack and water leakage in low temperature environment.

3, expansion nails and hooks, they are good helpers to fix the radiator on the wall. Nowadays, consumers are more and more accustomed to hanging radiators on the wall in pursuit of beauty, which requires expansion nails and hooks to have strong compressive and tensile properties to ensure that radiators will not move and work safely.

4. Reducing elbow can connect pipes with different nominal diameters or pipes with external threads and valves. Used to connect pipes with the same nominal diameter or pipes with external threads and valves to rotate pipes.
