PureFlex® CL2™ Chlorine/Bromine Transfer Hoses, Fluoropolymer, PTFE, Kynar® braid

PureFlex® CL2™ chlorine, bromine, & sodium hypochlorite transfer hose assemblies are specifically designed for the safe transfer of chlorine in the manufacturing, transporting, and packaging industries. It is ideal for loading/unloading barges, rail cars, tankers and filling 1-ton, 100 lb, and 150 lb cylinders. CL2™ hose has excellent chemical resistance and is not subject to stress fatigue or corroding like metal hoses. It is light weight, easy to clean, and resists corrosion from any exposure to moisture/humidity which can unintentionally enter systems. 

The thick “virgin PTFE” (as specified by the Chlorine Institute) consists of a one-piece, solid extruded tube with no smears or voids, helically convoluted to facilitate draining and cleaning and reduce transfer time cycles. CL2™ hose assemblies are 100% compliant with the Chlorine Institute's Pamphlet 6.

Product Features & Benefits

  • CORROSION RESISTANT: PTFE is fully resistant to the broadest range of industrial chemicals and has a zero-corrosion rate with lower life cycle costs. Does not stress fatigue or stress corrode like metal hoses.
  • RESISTANT TO WET OR DRY CHLORINE SERVICE: CL2™ hose consists of two layers of high pressure rated PVDF (Kynar®) braid that is resistant to wet or dry chlorine service (½" is single braided). PVDF braid is specified by the Chlorine Institute.
  • CLEANABLE: Non-Stick, low porosity tube is self-cleaning and does not trap bacteria and can be cleaned with steam, detergents, caustics or solvents.
  • SANITARY: FDA- approved materials meet or exceed Pharmacopoeia Class VI and 3A standards.
  • COMPATIBLE: Will not contaminate or impart a taste, color, or odor to any media. Monel® fittings for dry service. Hastelloy® C276 fittings for wet service.
  • FLEXIBLE: Ultra flexible engineered design that resists cracking and stress corroding.
  • DURABLE: Engineered for extended use in hostile environments involving severe chemical, thermal, and mechanical stresses. Does not suffer from aging or embrittlement like rubber even with extreme thermal cycling.
