Installation involves one extra consideration: the male end goes into another fitting rather than onto a pipe. So, if you’re inserting the street elbow into, for example, a ¾″ press coupling, first push the male end of the elbow into the coupling’s open end until it bottoms out. Ensure the elbow is oriented at the desired angle relative to that fitting. Then press the outer fitting (in our example, the coupling) – this action will crimp the coupling’s O-ring onto the elbow’s male end, sealing that joint. Next, take the female press end of the street elbow and insert your copper pipe into it, then press that end as usual. After these two press operations, you’ll have the street elbow firmly connected on both ends. Remember, like any press elbow, set the angle before pressing because the orientation will be locked in after crimping.
