Fittings and Manifolds for Drinking Water

Sulfone polymers can successfully replace brass, copper and stainless steel traditionally used in fittings and manifolds for drinking water. Globally approved for drinking water, these high-performance plastics provide greater design freedom and a host of performance attributes:


  • Freedom from corrosion
  • No heavy metals
  • Resists long-term hydrostatic stress
  • Withstands hot chlorinated water
  • Excellent creep resistance

Long-term hydrostatic strength (LTHS)
Radel polyphenylsulfone (PPSU) has the highest LTHS of any sulfone-based polymer, making it the material of choice for fittings in multi-layer piping systems operating under high pressures (up to 10 bar) and temperature (up to 95°C). For less demanding applications, consider Udel and Acudel resins. Click here for a detailed evaluation of LTHS for these three materials.

Oxidative Stability
Sulfone polymers are minimally affected by strong oxidizing conditions caused by the presence of chlorine in drinking water. When tested to highly aggressive conditions of ASTM F 2023, no measurable weight loss was observed.

Low creep under load
Unlike many other plastics, our sulfone polymers provide metal-like resistance to dimensional changes under sustained load. Click here for more information specific to Radel.
