PPSU PEX Fittings

NDL’s PPSU PEX fittings are a superior alternative to metal fittings in applications where local water supplies exhibit aggressive chemistries.

  • Chemical Resistance
    Constructed from durable PPSU (Polyphenylsulfone), they exhibit exceptional chemical resistance and maintain their integrity under varying temperatures (up to 200 F/93 C) and pressure conditions (up to 100 PSI/689 .5 kPa). They are resistant to many other chemicals found in processed and potable water.
  • Seamless Integration
    The standardized dimensions and seamless compatibility with PEX plumbing systems make these fittings a reliable choice for hassle-free installations and repairs.
  • Extensive Selection
    NDL PPSU PEX fittings are available from ½” to 1” diameter.
