America Standard Rubber Joint has characteristics of high withstand voltage, good elasticity, large displacement and balanced piping deviation, good effect on vibration absorption and noise reduction and easy installation. It can be widely used in the piping systems such as water supply and drainage, circulating water, HVAC, fire fighting, paper making, pharmacy, petroleum chemical industry, ship piping system, water pump, compressor and fan etc. The common application mediums are as follows, for example, transporting air with -15°C -120 °C, compressed air, water, sea water, oil, acid and alkali etc. Special application mediums such as transporting the above common mediums with -30℃-200℃, oil, strong acid or alkali and solid materials.
