$0.00 / EACH
Robson's Duct Seal-WB is a premium indoor/outdoor, water based, fiber reinforced, non-toxic, elastomeric sealant. It is designed to save energy by sealing joint sand seams in HVAC air ducts and plenums including metal, glass fiber duct board, flexible ducts, and most plastics to prevent loss of heated or conditioned air, and entry of water or dust. Special additives make Robson's Duct Seal-WB resist slumping and cracking, allow it to stretch like rubber, and remain flexible at cold temperatures.
