This is one of the new "sweeping" elbows. I like them for two reasons.


1- They are smooth walled and have a smooth radius bend. because of this a snake can be run down through them to clear out an intake hose that has become clogged with weeds.


2- I lose an entire threaded connection.


In this photo I have wrapped the threads with Teflon tape and before insertion I coated the Teflon tape with Real-Tuff pipe dope. Good pipe fitters often use both tape and dope and by doing so you can be at less risk of developing a leak.
