Both the nipple sets and elbow sets are shipped with the left hand threaded male and female ends fully engaged. Purple color coding on both parts also help to identify the left hand sections. Also, a directional label is affixed to the coupling as illustrated.

1. To make a connection, fully remove the elbow or nipple from the coupling.
2. Align the male ends correctly, i.e., purple to purple for the left hand and silver to silver for the right hand thread, to the coupling.
3. Slowly rotate only the coupling until you feel you have thread engagement on both ends. It is very IMPORTANT that you achieve thread engagement on both male ends within one and one half turns of the coupling for the system to be correctly assembled.
4. Once the males ends are engaged with the coupling continue to rotate the coupling until tight.
5. If a pipe wrench or similar tool is to be used to secure the coupling, it is VERY HIGHLY RECOMMENDED, that a second wrench or tool be used to secure the standing (or the installed conduit) end and prevent any movement when pressure is applied to the coupling.
