PVC Duct Tees
Bidding a job & need contractor pricing?
We've got you covered!
PVC duct tees are three way pipe fittings used in ductwork systems to split or combine the direction of airflow between multiple pipes. PVC duct tees provide a junction point where a main duct line can be divided into two or more branches for the distribution or collection of gaseous media. They are made specifically for use in ductwork and ventilation systems to transport air, gasses, fumes, exhausts, and waste emissions that may contain odors, dust, or other particulates to a point of release or treatment. PVC duct tees are used to complete the design and installation of PVC ductwork in industrial ventilation systems, agricultural air handling systems, and HVAC systems used in residential, commercial, and public buildings. They are also used in laboratories and manufacturing facilities due to their chemical resistance and durability.
Our PVC duct tee fittings are USA made by Harrison Machine and Plastic under the trade name Harrison SUPERDUCT®, one of the nation’s top manufacturers and brands of thermoplastic ductwork. PVC ductwork and tee fittings are to be used with air and compatible gaseous media in open air, non-pressurized applications only. They are not for use in pressure systems, with liquids, or with known incompatible chemicals. Always verify chemical compatibility prior to use.
PVC Duct Tee Sizes and Options
PVC duct tee sizes range from 3″ to 24″ in Iron Pipe Size (IPS) diameter. Large diameter duct tee fittings up to 60″ are available on request. Reducing duct tees are available to connect ductwork of different sizes and range in options from 3″ x 3″ x 2″ up to 24″ x 24″ x 20″. Our full selection in sizing and ability to meet custom size requirements demonstrates our commitment to precision, performance, and project completion.
PVC duct tee fittings come with belled socket type connection joints. For installation, use a professional quality PVC cement and primer for a secure fit. For large duct fittings above 14″, hot air welding is recommended.
