Industrial Flex Hose

Standard Rough Bore Metal Hose

TRU-FLEX offers standard (rough bore) metal hose manufactured from a single interlocking strip of metal that is spirally wound to form a durable flexible hose.

The overlapping/interlocking sections of the strip are able to slide at each convolution and allow the hose to flex. Depending upon the material used, packing and strip thickness, a standard bore metal hose can operate in a variety of temperatures ranging from — 100 ̊F to + 1200 ̊F. Standard bore metal hose can be manufactured from various grades of stainless steel alloys, aluminum, and coated steels (aluminized, galvanized, and tin plated).

Applications

  • Protective casing for hoses to prevent damage or kinking
  • Dry bulk product transfer from trailers and rail cars, etc.
  • Grain vacuuming
  • Dust collection
  • High temperature ducting
  • Engine exhaust

TRU-FLO Smooth Bore Metal Hose

TRU-FLEX offers TRU-FLO™ smooth bore metal hose as an alternative to traditional rough bore interlocking hose. TRU-FLO™ combines an outer armor layer with an inner liner for fast material transfer with minimal product degradation or damage.

The TRU-FLO™ hose is stronger and will last longer than other types of hose. TRU-FLO™ metal hose can be manufactured from either stainless or galvanized steel.

The inner liner provides superior strength and abrasion-resistance for longer hose life and excellent flow rates.

Applications

  • Granular materials
  • Pelletized plastics
  • Grains
  • Coal dust
  • And more…

Powerflex Low Leak Flexible Hose

Our patented Powerflex™ “Triple-S” profile designed hose is a premium interlocking strip wound hose that features low leak capability with excellent durability and bending strength. Power-Flex is an outstanding alternative for replacing either standard rough or smooth bore hose in many industrial applications; providing better flexibility, improved dry product transfer efficiency and reduced weight over standard lined hose.

Applications

  • High temperature/low leak ventilation and exhaust for industrial applications
  • Dry product transfer on various products
  • Commercial vehicle exhaust and severe duty coupling purposes

Performance Characteristics

  • Exceptional durability
  • Long life; Improved wall and bending strength
  • Highly resilient to pressure, impact and mechanical tension
  • Excellent absorption of axial, lateral and angular vibrations
  • Self-sealing interlocking profile (leakage lowers as pressure increases)

Design Profile

  • Double interlocked With radially shaped strips

Poly-Flex Metal Hose

Poly-Flex® metal hose is uniquely designed to not unwind when cut. It is self-cleaning and maintains flexibility longer than competitive products, can be field cut using a variety of methods, and does not require spot welding to hold the tail in place.

Applications

  • Exhaust hose
  • Agriculture grain transfers systems
  • Hot air ducting
  • Blower hose
  • Conveying shavings, chips, dust, lint, plastic pellets and other dry material

Material and Size Specifications

  • Galvanized and 304 Stainless Steel
  • Diameter (I.D.) range from 2″ to 8″
  • Standard length: 25 feet

Blowout Protection (BOP) Hose

TRU-FLEX’s Blowout Protection Hose was designed to both protect the contents of the hose from external damage and prevent blowouts from interior pressure. This product is manufactured “loose-wound” for flexibility and protects against damage from abrasion, chemical contacts, crushing, and bending.

Applications

  • Protective armor for plastics, pvc hoses, or rubber hoses
  • Ideal protection for hydraulic lines
  • Conduit for wire or pipes

Available Sizes

  • Inside diameter: 1.625”, 1.875”, 2” and 2.5”

Material and Size Specifications

  • Standard weight: .012″ Type 304 stainless steel
  • Heavy weight: .015″ Type 304 stainless steel — all sizes only 1.875”
  • Standard length: 100 feet

Floppy Flex Protective Armor Hose

Floppy-Flex Protective Armor Hose features a heavy duty interlock design that enables it to fall back on itself without pressure and convey materials as it coils around sharp bends or confined areas. The snakelike flexibility of Floppy-Flex Metal Hose makes it ideal for many applications because it is easy to handle and can be used in confined or open areas.

Applications

  • Armor casing/protection
  • Steam hose liner
  • Shielding conduit
  • Gravity conveyor hose
  • Removal of dust, lint, sawdust, plastic pellets, and other dry material

Available Sizes

  • Inside diameter: .1875”–2.2”
  • Standard mill lengths
  • Special diameters and lengths are available upon request.
