ITW GSE is the premier supplier of PCA hoses. The insulated PCA duct is an extremely flexible heating and air-conditioning duct constructed with wire reinforcement for durability. The PCA 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. These ducts come with zippers and velcro to easily attach additional sections forming longer duct assemblies.
