Reducing tee
A threaded reducing tee creates a branch in which the nominal size of an opening defined by the product form differs from the main run. That size relationship distinguishes it from an equal tee; however, the generic title does not identify which opening is reduced, the thread arrangement, or any thread form, material, or coating. Selection must define the exact run and branch sizes and sequence, branch direction, flow distribution, local loading, sealing method, assembly clearance, and maintenance access from project drawings and specifications rather than a fixed family assumption.
