What is threadolet?

A threadolet (threaded outlet) is the same basic design as a “weldolet“. However the main difference is the fitting has a female threaded connection to mate to the branch connection. This makes a 90° branch and comes in full size or reducing for a straight piece of pipe. It typically is in the size range of 1/2″ to 2” and is welded over a hole either drilled or burned in the pipe.

Depending of the relative size of the olet and the main pipe run the affect can vary from no affect to causing the header to bow or warp due to the heating and cooling of the weld. A good run of thumb is to never use an olet that is larger that 1/2 the size of the main pipe run.
