Hello! Thanks for asking about the 2 x 1 1/2 x 3/4 black malleable iron tee. No, an iron tee is not specifically a Schedule 40 fitting. The term "Schedule 40" is typically associated with PVC (Polyvinyl Chloride) or CPVC (Chlorinated Polyvinyl Chloride) pipes and fittings. Iron fittings, on the other hand, are commonly used with metal pipes, particularly cast iron pipes and steel pipes. We hope this information helps. If you still wish to purchase this fitting, just click Add to Cart and complete the form. Have a nice day!
