High Density NBR soft foam Rubber Pipe Insulation For HVAC System RUBBER PIPE/TUBE
AK-Flex NBR tube/pipe is a black, flexible elastomeric foam tube used to conserve energy and prevent condensation on piping applications. The tube closed cell properties create exceptional thermal and acoustic insulation, protect against moisture penetration and provide the best solution for applications within a -280°F to +221°F temperature range. It is primarily used in the HVAC/R market and comes in 6 feet or 2 meet length. It is 25/50-rated, according to ASTME-84 standards for surface burning characteristics of building materials.
