NBR tube/pipe is a black, flexible elastomeric foam tube used to conserve energyand prevent condensation on piping applications. The tube closed cell properties createexceptional thermal and acoustic insulation, protect against moisture penetration and providethe best solution for applications within a -280°F to +221°F temperature range. It is primarilyused in the HVAC/R market and comes in 6 feet or 2 meet length. It is 25/50-rated, accordingto ASTME-84 standards for surface burning characteristics of building materials.
