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
resistanceperformance. They have been widely used in ultrafiltration (UF) membrane device in the s
ystem of water desalination.
