This forms an air-tight and leakproof three-ply mechanical seam. It is self-supporting and corrosive resistant. With its ULC-S110 and UL-181 Class 1 rating, it provides excellent strength and flexibility. It is adaptable to any heating, ventilation and air conditioning system, even with high-pressure.
