  • Chemical resistance and purity levels are as recommended for the base materials.
  • No metals or lubricants are used in construction, internally or externally.
  • Custom membranes may be supplied upon request.

Materials of Construction

N/A

Body:

  • PVC: Polyvinyl Chloride
  • CPVC: Chlorinated Polyvinyl Chloride
  • PP: Polypropylene homopolymer, glass & mineral reinforced

Membrane:

  • Standard: PTFE, also available in:
  • FPM: Viton®, Fluorine elastomer
  • EPDM: Ethylene Propylene elastomer
