ITW GSE is the premier manufacturer of PCA Hoses. The compact and insulated Flat Duct is an extremely flexible heating and air-conditioning duct. It is constructed without wire reinforcement, allowing it to be flattened and rolled when not in use for compact storage.
The Flat Duct hose is constructed of two-ply, flexible heavy duty and highly abrasion resistant vinyl coated fabric. The interior construction is non-rip nylon with moisture proof insulation between the plies.
