Armaflex Class O Pipe Insulation 67mm x 13mm

Armaflex Class O Pipe Insulation 67mm x 13mm is made for 67mm copper, which is 66.7mm on the outside, with a 13mm foam jacket. The thin wall is meant for large heating headers and mains inside warm plant rooms, where heat loss is the main concern.

About Armaflex Class O Pipe Insulation 67mm x 13mm

67mm copper is mostly seen on commercial heating and in plant rooms, on headers that feed several circuits. Left bare, a header like that warms the whole plant room. A 13mm wall cuts that loss while keeping the finished size small enough for tightly spaced pipework.

• For 67mm copper (66.7mm outside)
• 13mm closed-cell wall
• About 93mm overall fitted
• 2 metre lengths

Cut the tube along its length, close it round the pipe and seal the seam with Armaflex 520 adhesive. Make up small pieces for valves and tees, so the lagging stays continuous. The finished size is around 93mm, which fits most bracket spacings. Thicker walls for 67mm pipe are in the pipes, hoses and insulation section.
