Wide Component Range

SIGMA® comes with an extensive range of components, specifically designed to meet the requirements for multi-functional applications serving a variety of fuels for domestic stove installations. The product is available in four imperial diameters covering 127mm, 152mm, 178mm and 203mm.


Robust Lazer Weld Seam

The fully welded construction combined with a high-performance/high-density insulating medium provides the optimum level of performance required for today’s modern high-efficiency appliances. This product has been developed to offer a smooth aesthetically pleasing joint without the need of an additional locking band.


Bespoke Component Manufacturing

As a British manufacturer, SFL, are able to offer a quick turnaround of specials. Whether it’s a special manifold design, bespoke appliance adaptors or special sizes fitting, we are here to help.


Smooth & Clean Jointing System

the SIGMA joint is designed to offer the appearance of a smooth continuous pipe, offering a very aesthetically pleasing finish to the product. The aesthetic finish is achieved by slightly reducing the diameter of the male end to allow engagement with the female end.


10 Year Warranty

The SIGMA range is backed up with a comprehensive 10-year product warranty. The 10-year warranty is a measure of our confidence in the quality and reliability of our flue systems and gives added peace of mind for any installation.
