Stainless Steel Polylock

Polylock is manufactured from a single stainless steel metal strip, precision-formed around a mandrel to create a fully interlocked section. Built-in flats in the hose wall deliver excellent anti-torsion performance, preventing the hose from twisting or unwinding during processing. This stripwound metal hose design ensures: 

  • Great Flexibility
  • High Mechanical Strength
  • Long Service Life 

Primary Applications

Polylock is a versatile industrial hose ideal for a wide range of high-temperature and heavy-duty uses, including:

  • Vehicle and industrial exhaust systems
  • Ducting and fume extraction
  • Material handling and abrasion-resistant transfer

Maximum Operating Temperature

Polylock is engineered to withstand temperatures up to +650°C, making it suitable for extreme heat applications.

Please note: All listed diameters refer to internal diameter (ID). Please confirm sizing before ordering.

We can manufacture alternative lengths, as required – please contact us for non-standard lengths.

Special Features

Special Features

Polylock has a series of flats built into the hose wall to provide anti-torsion properties which prevents the hose from unwinding when cut. There is no need for tack welding which makes it easier to process on site.  

Flow Direction from Whitehouse Flexible TubingFlow Direction

Our Polylock hose provides a smooth surface particularly in one direction due to the design of its section. We recommend that our customers ensure that the media flow through our tubing follows the Flow Direction of the Hose. There are many benefits to this including protection of the media and tube in addition to ensuring Optimum Flow Characteristics. In addition, it helps prevent damage to the media or tube when used in conjunction with abrasive materials such as plastic pellets.
