Brass Reducing Adapters
View Tameson's range of brass reducing adapters. A reducer nipple is a short piece of pipe with female threads on one side and male threads on the other. There are reducing adapters (male thread is smaller than the female thread) and reducing rings (male thread is larger than the female thread). These are reducing adapters, so the male thread is smaller than the female thread.
