Overview

Corroflon

PTFE-lined hose for chemical and process fluid transfer

A fluoroplastic hose with a flexible convoluted PTFE liner. Corroflon has shallow convolutions which minimise the restriction in flow rates, with external wire reinforcement to ensure full vacuum and kink resistance in process applications.

Features and benefits

  • Natural or anti-static patented PTFE liner
  • The shallow convoluted liner design delivers exceptional flexibility while minimising restriction in flow rate
  • Vacuum and kink resistant
  • High temperature and pressure capability
  • Chemical resistant
  • PTFE lined and non-lined end fittings
  • Range of braid, cover and external protection options available
