Armaflex Class O Pipe Insulation 67mm x 19mm

For 66.7mm copper, Armaflex Class O Pipe Insulation 67mm x 19mm has a 19mm foam wall. Fitters choose it on plant room headers and on large heating mains crossing cooler corridors and voids.

Armaflex Class O Pipe Insulation 67mm x 19mm for headers and mains

The 19mm wall is a middle grade. On a warm pipe, it holds in more heat than the light grade, and on a cold one it gives better cover against sweating in normal indoor air. The rubber-based foam is cut with a knife, so making up covers for valves and fittings is quick work.

• Bore to suit 67mm copper
• 19mm wall
• About 105mm across fitted
• 2 metre tubes

At about 105mm overall, plan the spacing on brackets and allow larger openings through walls. Split and wrap the tube round fixed pipe, then glue the seam and butt joints with Armaflex 520 adhesive. Mitre the ends at bends so the corners close neatly. Every other size appears in the pipes, hoses and insulation range.

Common Questions

Where is 67mm x 19mm Armaflex used?

On large copper headers and mains in plant rooms, and on runs through cooler parts of a building. It is the middle grade of the three.

Can I fit it to a header with many branches?

Yes, but plan the cuts. Fit the branch pieces first, then notch the header tube round them and glue every joint.

How many 67mm x 19mm lengths cover a 14m header?

Seven 2m lengths cover 14m of straight pipe. Branches and valves need extra.
