How to measure?
Measure the Outside Diameter (OD)
Pipe insulation sizes refer to the outside diameter of the pipe — not the bore (internal diameter).
Wrap a tape measure around the pipe, divide by π (3.14) to get the OD. Or use calipers across the outside of the pipe directly.

Armaflex EVO Self Seal Domestic Pipe Lagging Kit — Premium Class O Insulation for Heating & Plumbing
The premium choice for domestic heating and plumbing pipework. Armaflex EVO Self Seal is a closed-cell nitrile foam pipe insulation with a factory-applied adhesive strip — simply peel, wrap, and press for a tool-free, professional finish every time.
Each kit includes the insulation you need plus Armaflex L414 lagging tape for finishing joints and cable ties for securing the lagging — everything in one order, nothing missing on site.
Every Kit Includes
- ✅ Armaflex EVO Self Seal Pipe Insulation — Class O, Black Nitrile Foam, 2m lengths (your chosen pipe size and wall thickness)
- ✅ 1 × Armaflex L414 Lagging Tape — the correct Armaflex-branded tape for sealing butt joints and overlaps on EVO insulation
- ✅ 1 × Cable Zip Ties — Bag of 100 — for securing insulation neatly on exposed pipework
Why Choose Armaflex EVO Self Seal?
- Self-adhesive closure strip — peel, wrap and press for a fast, tool-free installation; no adhesive required
- Class O fire rated — compliant with UK Building Regulations and BS EN 13501; suitable for domestic and commercial installations
- Closed-cell nitrile foam — vapour-resistant and moisture-proof; superior performance vs polyethylene foam for heating and hot water pipework
- UV-stable black finish — suitable for exposed pipework without additional cladding
- 2m lengths — easy to handle and cut to length on site with minimal waste
Self Seal vs Standard EVO
The self seal version is ideal for heating, hot and cold water, and domestic plumbing pipework. For refrigeration, air conditioning, or chilled water pipework where condensation control is critical, use our Armaflex EVO Refrigeration & AC Kit (unslit, glued joints) instead.
Choosing Your Kit Size
Select the pipe outside diameter (OD) and insulation wall thickness, then choose your run length (2m, 4m, 6m, or 10m). Common domestic copper sizes: 15mm, 22mm, 28mm. For pipes in unheated spaces, 19mm or 25mm wall thickness is recommended.
