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 Pipe Insulation — Black Elastomeric Foam, 2m
Armaflex EVO is Armacell's flexible closed-cell elastomeric foam insulation for HVAC, refrigeration and process-equipment applications. The Self Seal tube is supplied pre-slit with a factory-applied pressure-sensitive adhesive closure, making retrofit installation around existing pipework faster and cleaner.
The closed-cell structure provides thermal insulation and high resistance to water-vapour diffusion, while the EVO formulation delivers low smoke development and built-in Microban® antimicrobial protection.
Key Benefits
- Self-adhesive closure: factory-applied seal for faster installation on straight pipe runs
- Reaction to fire: tubes achieve Euroclass B(L)-s2,d0 to EN 13501-1 and Class 0 to BS 476 Part 6
- Condensation control: closed-cell structure with water-vapour diffusion resistance factor μ ≥ 10,000 for the 9–25mm tube thicknesses in this listing
- Low thermal conductivity: λd ≤ 0.033 W/(m·K) at 0°C for tube thicknesses up to 25mm
- Microban® antimicrobial protection: built into the insulation material
- Flexible and lightweight: suitable for heating, chilled-water, refrigeration and air-conditioning services
Technical Specifications
- Material: Flexible elastomeric foam based on synthetic rubber (FEF), to EN 14304
- Colour: Black
- Length: 2m per tube
- Closure: Factory-applied self-adhesive longitudinal closure
- Service temperature: -50°C to +85°C for products with a self-adhesive layer
- Thermal conductivity: λd ≤ 0.033 W/(m·K) at 0°C and 0.038 W/(m·K) at 40°C for tubes up to 25mm wall thickness
- Water-vapour diffusion resistance: μ ≥ 10,000 for tube thicknesses up to 25mm
- Reaction to fire: B(L)-s2,d0 to EN 13501-1; Class 0 to BS 476 Part 6
- FM Approval: 4924 — pipe and duct insulation
- UV exposure: outdoor installations should be protected from UV radiation with a suitable covering within 3 days of installation
- Antimicrobial: Built-in Microban® antimicrobial protection
Wall Thickness Selection Guide
- 9mm wall — suitable where a thinner insulation layer meets the thermal and condensation-control requirement
- 13mm wall — widely used for domestic and commercial building-services pipework
- 19mm wall — increased thermal resistance for chilled-water, refrigeration and heating applications
- 25mm wall — higher insulation thickness for applications requiring greater thermal performance

Applications
- Chilled-water flow and return pipework
- Heating and hot-water pipework
- Refrigeration and air-conditioning services
- Fan-coil and HVAC connections
- Heat-pump primary circuits where the selected temperature range is suitable
- Process-equipment pipework
Installation
Install in accordance with the current ArmaFlex application manual. Open the pre-slit tube, position it around the pipe, remove the release film from the self-adhesive closure and press the seam firmly together along its full length.
The self-seal strip closes the longitudinal seam, but butt joints, bends, fittings and fabricated details still need to be sealed correctly using a compatible ArmaFlex adhesive. Armacell lists ArmaFlex ECO 550 and ArmaFlex 525 as certified adhesives for AF/ArmaFlex EVO; ArmaFlex 520 may also be used for tubes.
