Fiberglass Snap-On Pipe Insulation – A preformed high-density resin-bonded Fiberglass insulation, molded in one meter lengths. A single longitudinal seam enables the sections to open and encircle the pipe and to snap closed after placement.


Snap on pipe insulation is specifically designed for application to both hot and cold service piping systems operating at temperatures from -20°C up to 450°C . Suitable for application on chilled water and refrigerated lines, hot water, steam & condensate lines, in domestic, commercial & industrial applications.


Available in a wide range of standard nominal bore steel and copper pipe diameters over a range of insulation thickness.
