K-Flex ST self-seal, Nitrile Rubber pipe insulation is a low-cost solution to lagging your pipes. K flex helps to effectively reduce energy costs via preventing heat loss or gain to all types of pipework.

Nitrile rubber is flexible and light in weight and the best part is that this pipe lagging comes with self-adhesive strips, which means you can install it yourself even if you are an amateur DIY'er. 

As sometimes Armaflex lagging is used as a synonym for Nitrile rubber insulation as a whole, it is worth pointing out that Kflex is made from the exact same material as Armaflex pipe insulation.

This self-seal, nitrile rubber foam pipe insulation helps to increase the life and performance of pipework by reducing heating requirements and effectively shielding the pipework from corrosion if installed correctly. It is suitable for use in all aspects of residential, commercial and industrial applications.

It can also be used to insulate pipework equipment, tanks and used as valve insulation. K flex pipe insulation helps give an energy-saving performance and has an inherent resistance to microbial growth and moulds. The nitrile rubber pipe sections protect the pipes from dirt, rust, condensation, freezing and other issues.
