What's in the Kit

• 1 × Armaflex EVO Self Seal Pipe Insulation Lagging — Black Nitrile Foam, Class O, 2m (your chosen pipe size and wall thickness)
• 1 × Armaflex 520 Pipe Insulation Adhesive (250ml, 500ml, or 1.0ltr — choose below)

Choosing the Right Size

Select the pipe outside diameter (OD) and insulation wall thickness to match your specification. Common domestic copper sizes: 15mm, 22mm, 28mm. For condensation control on chilled pipework, a thicker wall (19mm or 25mm) is typically required — check your design spec or ask us if unsure.

Complete the Job Right

For a fully sealed installation, add Armaflex Lagging Tape to finish butt joints and overlaps. Available separately in our store.
