Aerofoam® Lap Seal Tubes

Aerofoam® Lap Seal Tube is an NBR pre-slit flexible closed cell elastomeric insulation tube with an adhesive overlap seal to prevent condensation and heat loss control. Lap Seal Tubes make the insulation installation trouble-free and cost effective, perfect if you are looking for convenience along with comfort. Maintaining traditional insulation can be extremely overpriced and complicated. The installation of Lap Seal Tubes results in ease of use for the installer due to the strong pressure sensitive adhesive (PSA). Aerofoam® Elastomeric Lap Seal Tubes have been manufactured to reduce installation time and reliance on other adhesive solutions. Aerofoam® Lap Seal Tube closed cell elastomeric thermal insulation tubes with factory applied double seal closure system are water vapor resistant, mold and mildew resistant demonstrating improved thermal performance. Aerofoam® Lap Seal Tubes are ideal for a variety of applications including welded refrigerant pipes, pipe repair and insulation replacement to name a few. Lap Seal Tubes by Aerofoam® does not require additional glue or accessories to be utilized during the installation process.
