| 90° Elbow | 45° Elbow | 180° Elbow | Tee | Cross | Reducers | Caps & Stub Ends |
The function of a elbow is to change direction or flow in a piping system. By default, there are 5 opportunities, the 45°, 90° and 180° elbows, all three in the "long radius" version, and in addition the 90° and 180° elbows both in the "short radius" version.
