A threadolet is akin to a sockolet, but it distinguishes itself by having a female threaded connection, where the branched pipe is screwed onto the fitting. This configuration results in a 90-degree branch that can accommodate either a full-size or reduced straight pipe. The body of the threadolet is made of high-quality forgings, and the material used is the same as that of the pipeline, such as carbon steel, alloy steel, stainless steel and so on.
