This is a 100mm / 4 inch diameter 6m flexible ducting ideal for high, medium, and low pressure ventilation and air conditioning systems.

Tecflex 800S is a new and improved version of the best selling Tecflex 800. This new construction with the supporting steel wire helix now embedded between two layers of fabric produces approximately 10-25% less resistance! Tecflex 800S is also environmentally friendly; solvents are no longer the principle bonding agents. The estimated solvent reduction is over 90%!

Tecflex 800S is suitable for use in high, medium and low pressure ventilation and air conditioning systems. It is also suitable for use in fume extraction systems. Due to the materials used in its construction Tecflex 800S is able to withstand repeated flexing without damage or kinking.

  • Tecflex 800S complies with the requirements of HVCA specification DW144.
  • Suitable for high, medium and low pressure applications.
  • Fire resistant: Complies with the requirements of BS476.
  • Suitable for air conditioning and fume extraction systems.
  • Complies with the requirements of DW144.
  • Manufactured from puncture and tear resistant materials.
  • Withstands repeated flexing without damage.

Tecflex 800S is manufactured from a tough, grey coloured fabric comprising a pvc coating bonded to a tightly woven glass cloth to provide a tough yet highly flexible, puncture resistant, ducting. The fabric is supported by an encapsulated high tensile steel wire helix. Encapsulation of the wire helix within the fabric overlap provides an exceptionally smooth inner wall resulting in excellent friction loss characteristics.

The selection of an exceptionally durable fabric together with carefully controlled manufacturing techniques has resulted in a highly compressible, ultra flexible ducting. Tecflex 800S compresses down to approximately 10% of its extended length – making connections in confined spaces considerably easier and reducing installation times. 
Tecflex 800S is supplied in economical 6 metre lengths. However, if longer lengths are required, two lengths of the same diameter may be screwed together and secured with PVC Tectape to provide a permanent airtight joint. 

Un-insulated flexible ducting for joints or connections shall be Tecflex 800S. It shall be manufactured from a tight weave glass fibre fabric coated with a grey coloured PVC and supported by an encapsulated high tensile steel wire helix. The duct shall meet the requirements of BS476 parts 6, 7 and 20. 

Technical Data

  • Diameter: 100mm, 4 inch diameter
  • Temperature Range: From –20°C to +70°C
  • Air Velocity: 25M/S maximum
  • Working Pressure: Maximum 2000 Pa positive up to 406mm dia.
  • Colour: Silver Grey
  • Standard Length: 6 Metres (longer or shorter lengths can be produced subject to minimum quantities).

Fully extend ducting, then cut to exact length required using a sharp knife and pliers. We recommend that joints be sealed on medium and high pressure applications using Tecseal or Tectape XT. To fix Tecflex 800S to spigots we recommend the Tecfix banding or clip system.
