PCA Wire Wound Duct Velcro and Zipper

The extremely flexible insulated PCA duct for heating and cooling is constructed with wire reinforcement for strength and durability. The PCA hose is made of vinyl-coated heavy-duty, flexible, two-ply fabric that is highly abrasion-resistant. The interior construction is non-rip nylon with moisture-proof insulation between the plies. These ducts have Velcro and zippers that make it simple to join several parts together to create longer duct assemblies.
