Stepping down an HDPE line
Distribution lines usually narrow as they move away from the source, and a reducing coupler makes that step on a straight run in one fitting. Both ends grip HDPE pipe by compression, so the joint can be made up and remade with hand tools. Larger reductions are listed in other joint systems, such as the rubber ring Reducing coupler Rubber Ring Joint.
