Flexline Metal Hoses

Jacketed Metal Series

  • Construction: Common inner hose and outer hose configurations appear below.
  • Pressures illustrated are for single braid construction. Double braiding will increase pressure ratings. Flexline can achieve a greater degree of product heating / cooling by increasing the size of the exterior hose. Various alloys are available.
