Model 75N 

Plastic Flexible Coupling

The Model 75N is designed on the purpose of solving the corrosion problems happened in low pressure piping systems. Our couplings are manufactured in good quality reinforced nylon injected through high temperature. Therefore our couplings have high strength and toughness,and very good corrosion resistance performance. They have been widely used in ultrafiltration(UF) membrane device in the system of water desalination.
