Product Information

Full details

The AF/Armaflex Evo Nitrile Pipe Insulation is an ideal solution for professional HVAC technicians and plumbers seeking reliable condensation control and energy efficiency in pipework. Its primary benefit is a high-performance closed-cell structure combined with integrated Microban antimicrobial protection, which prevents both energy loss and bacterial growth. However, users should note that as a 2-metre length product, it requires precise measurement and specific adhesives to ensure seamless, airtight joints during installation.

Extended Product Information

FAQs

Can this product be used outdoors?

While highly durable, it is primarily intended for indoor use. If used outdoors, it must be protected with a UV-resistant coating or cladding.

Does this insulation need a protective jacket?

The material is robust enough to be left bare in most interior applications, but mechanical protection may be added in high-traffic areas.

Is the Microban protection permanent?

Yes, the Microban antimicrobial additive is integrated into the material during manufacturing and remains effective for the lifetime of the insulation.

What is the operating temperature range?

Please consult the technical datasheet for your specific batch, but it is generally designed to handle standard domestic and commercial hot/cold water temperatures.

Can I use standard duct tape to seal the joints?

No, standard duct tape is not sufficient for a vapour-tight seal. Always use the specified professional adhesive or matching Armaflex tape.

Troubleshooting

Condensation forming on the outside of the insulation

Check that all longitudinal seams are fully sealed with adhesive and that there are no gaps at the pipe joints.

Material tearing during installation

Ensure your cutting tool is very sharp. Avoid pulling or stretching the insulation excessively while wrapping it around pipes.

Adhesive not bonding correctly

Ensure the surface of the insulation is clean and dry. Apply adhesive thinly to both surfaces and wait for it to become 'tacky' before pressing firmly together.

Pros and Cons

Pros

  • Excellent resistance to microbial and mould growth
  • Highly flexible material makes it easy to install around bends
  • Effective at preventing pipe sweating and condensation
  • Durable, fibre-free composition
  • Helps lower energy consumption by reducing heat transfer

Cons

  • Requires professional-grade adhesive for secure seams
  • Rigid application requirements for complex pipe geometries
  • Fixed 2-metre lengths may result in more joints for very long runs

Setup, Compatibility & Care

To install, measure your pipe diameter carefully to ensure a snug fit. Clean the pipe surface to remove grease or debris before application. If you need to cut the material, use a sharp, thin-bladed knife to avoid tearing the foam. When bonding the longitudinal seams or butt joints, use the manufacturer-approved Armaflex adhesive to ensure a vapour-tight seal. The material is compatible with most standard copper and steel plumbing systems. For long-term care, simply wipe down the exterior with a damp cloth; the Microban protection is built into the material and does not require special cleaning agents to remain effective.
