Product Made in Japan
Model: NK-7400
NFK expansion joints are used in gas and liquid transport system lines used by steel making, chemical and industrial plants to transport substances such as air, water, gases, steam, oil and exhaust gases. They can compensate for expansion and contraction caused by temperature differences in air-conditioning/sanitation lines in buildings and other structures. They also handle conditions such as line center misalignment, vibrations, foundation subsidence and earthquakes.
