CPVC Duct Rain Caps Style B are preventive ductwork fittings used to protect ventilation systems from precipitation, debris, and pests. Style B CPVC rain caps are zero static pressure loss fittings used to complete the exterior vent of a ductwork system made to expel exhaust, fumes, vapors, or air that may contain dust or particulates generated by onsite activities. They are uniquely engineered to allow ventilation expulsion without significantly modifying system airflow dynamics and operating pressure. CPVC Duct Rain Caps Style B are long and slender for an aerodynamic design that reduces drag and friction from wind, offering better protection and stability during high winds.
These Style B Rain Caps are USA made and manufactured from Type IV Grade I Corzan CPVC per FM 4910 and ASTM D1784 specifications to create a long lasting, reliable product. The rain caps are mechanically durable, corrosion resistant, and compatible with a wide range of commonly used industrial and commercial chemicals. SUPERDUCT® Style B Rain Caps come in a complete range of sizes from 2″ to 12″ to match different ductwork systems and project needs. The duct fittings are Iron Pipe Size (IPS) sizing standard and come with a belled end socket connection.
