A PPR reducing elbow turns a PPR line and changes pipe size in one fitting.
It saves a separate reducer. As a result, the layout is shorter and has one joint less.
What is a PPR reducing elbow?
A PPR elbow turns a PPR pipe run, usually through 90 or 45 degrees. Plain elbows have two fusion sockets, while threaded elbows have a brass thread on one end for taps and valves.
Because each joint is fused, PPR elbows do not leak at threads or rust. Special types include reducing elbows, elbows with a wall support and double elbows.
