Couplings

Nylon Couplings

EWP-USA's Victaulic-type Nylon grooved flexible pipe coupling is a reliable alternative to stainless steel. Designed for RO Systems Membrane Housing is made of high-quality Nylon plastic, this flexible coupling is extremely corrosion resistant and provides a cost-effective solution for piping connections in low-pressure applications up to 300 PSI.​ It is designed for the purpose of solving the corrosion problems happening in low-pressure piping systems. The couplings are manufactured in quality reinforced nylon injected through high temperatures. Therefore the couplings have high strength and toughness, and good corrosion resistance performance. They have been widely used in ultrafiltration (UF) membrane devices in the system of water desalination.
