Transfer Hoses



100% Compliant with the Chlorine Institute's Pamphlet 6

CL2™ Hose Services

  • Chlorine
  • Bromine
  • Sodium hypochlorite
  • Other highly aggressive oxidizers or corrosives

PureFlex CL2™ 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 hose. It is light weight, easy to clean, and resists corrosion from any exposure to moisture/humidity which can unintentionally enter systems. CL2™ hose assemblies are 100% compliant with the Chlorine Institute's Pamphlet 6.

CL2™ Advantages

  • Corrosion Resistant - PTFE is fully resistant to the broadest range of industrial chemicals and has a zero corrosion rate with lower life cycle costs.
  • 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.
  • 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 ernbrittlement like rubber even with extreme thermal cycling.

PureFlex options on CL2™ hose chafe guards
include (left to right):

  • PVDF Kynar® heavy braid
  • HDPE abrasion guard
  • CPE pin pricked rubber

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.

Thick “virgin PTFE” (as specified by the Chlorine Institute) consist of a one-piece, solid extruded tube with no smears or voids, helically convoluted to facilitate draining and cleaning and reduce transfer time cycles.

PureFlex TASK-LINE® Gaskets are manufactured with virgin PTFE resin molded around and through a stainless steel perforated metal insert. TASK-LINE Gaskets are recommended for chlorine service due to many advantages:

  • Zero corrosion rate
  • Blow-out protection
  • Seats and releases easily
  • -100°F to +400°F
