Armaflex Pipe Insulation Lagging Tape 50mm x 3mm x 15m Black Foam Class O

Armaflex Pipe Insulation Lagging Tape – 50mm x 3mm x 15m, Black Foam Class O

Armaflex Lagging Tape is a self-adhesive black nitrile rubber foam tape designed to seal joints, butt ends, and irregular sections on Armacell Class O pipe insulation. It provides a continuous, professional finish on insulated pipework, preventing heat loss, condensation, and air infiltration at vulnerable connection points.

Key Benefits

• Class O fire rated – meets the same fire classification as Armaflex AF and Armaflex Class O pipe insulation
• Self-adhesive backing – peels and sticks directly to insulation surfaces; no additional adhesive required for most applications
• Closed-cell nitrile foam – low thermal conductivity and vapour resistance prevent condensation at joints
• Flexible and conformable – wraps cleanly around bends, tees, valves, and irregular fittings
• Noise reduction – foam construction dampens pipe noise and vibration
• Versatile – also suitable as draught sealing tape for doors, windows, and service penetrations
