"INTER-FLEX" INTERLOCKED 
FLEXIBLE METAL TUBING

DESCRIPTION:

UNAFLEX® "INTER-FLEX" Style U-12 and U-20 Interlocked Flexible Metal Tubing is constructed of a variety of metals (galvanized or bright steel, aluminum, brass, bronze or stainless steel) in strip thicknesses of .010" to .012" (Style-U-12), and .018" to .020" (style U-20). 

Coupling options available are: soldered, brazed or welded-on pipe nipples, couplings or flanges. Special fittings are also available on request. They are widely used in the industrial, marine and automotive fields for armoring, shielding and as conveyor hose. Extreme flexibility, ruggedness and their ability in achieving irregular curves and angles makes them ideal for a wide variety of applications.

APPLICATIONS:

  • Ventilator, blower hose
  • Hot air, fume, fresh air ducts
  • Shielding electrical wiring, conduit and refrigeration lines
  • Engine exhaust 
  • Breather tube connections
  • Heater connections
  • Bendable tail pipes
  • Exhaust fume collectors
