Chemical Plant Construction Products

Quick couplings made of PTFE/PFA

Chemically resistant quick couplings made of PTFE/PFA - self-sealing, free of dead spaces and contamination.

Our unique couplings are resistant to even highly aggressive chemicals used in the chemical industry. An example of future-oriented solutions made of plastic.

  • Universal use with highly aggressive chemicals
  • No wetted metal parts
  • Contamination-free
  • Simple installation, even in existing pipes
  • Enhanced flow design, low pressure losses
  • Leak-free during coupling
  • Both halves of the coupling are self-closing
  • No dead spaces during coupling
  • One-hand-use possible
  • Colour coding possible
  • Electrically conductive design on request
  • Kalrez® seals with FDA conformity on request
  • Reducers for additional connection sizes on special request
