Good soft pp compression valve, the pipe fittings are not easy to be squeezed and deformed, even if deformed, it will not break, and greatly reduce the amount of joints; it can resist the corrosion of chemical elements in the water, and the smooth inner surface can avoid the formation of scale; the pipe fittings can withstand the normal temperature The water pressure is 45 kg/cm², and the tube's non-deformation temperature is 112 degrees Celsius less
