Armaflex Class O Pipe Insulation 67mm x 25mm

Armaflex Class O Pipe Insulation 67mm x 25mm puts a 25mm wall of closed-cell foam round 67mm copper. Use it on chilled water mains, cold feeds in unheated voids and any large pipe where condensation or frost would be a problem.

Why the heavy grade of Armaflex Class O Pipe Insulation 67mm x 25mm

On cold pipework, thin lagging can leave the outer face cold enough for water to form on it. The 25mm wall keeps that surface warmer, so the pipe stays dry. The closed cells mean the foam does not absorb moisture, which helps it keep working for years.

• For 67mm copper
• 25mm closed-cell foam
• About 117mm overall once on
• 2 metre lengths

With a finished size near 117mm, measure before you start, especially at wall openings and where pipes run together. Glue every seam and end joint, and use insulated supports at the brackets on chilled lines. A long, sharp blade gives the cleanest cut. Other bores are in pipes, hoses and insulation.

Common Questions

Why choose the heavy grade on 67mm copper?

Use the 25mm wall on chilled water and cold mains in damp or unheated areas. It gives the most condensation control listed for this size.

Is the 67mm x 25mm tube easy to handle?

It is bulky and stiff, so cut it on a bench where you can and offer it up in sections. Glue each section as you go.

What adhesive do I need for 67mm x 25mm?

Armaflex adhesive on every seam and butt joint, applied to both faces. Let it go touch dry before pressing them together.
