Used with 4" galvanized round tube on my dust collection system where line connections were required. They were much cheaper than round galvanized duct tees and were compatible with round duct, plastic fittings and flexible hose. Much better than using loss-saving haircuts. You will also need to connect a copper wire connecting the round channels for grounding. Good work. It's easy to connect metal ducts to a plastic tee by riveting the connections and adding metal tape to seal. Provides a good solid rigid connection. PVC prices are rising so much that galvanized pipe has become an economical solution for distributing these tees.
