Male Branch Tees are very similar to traditional Straight Pipe Tees where they are used to connect pipelines with another pipe of the same size at a right angle with the line. The difference is these Male Branch Tees feature a male thread on the branch allowing a female pipe thread to be connected at 90°

Hex bushings are used to reduce the size of female threads from a larger to a smaller diameter. Hex Bushings are threaded fittings that have male threads on the outside and female threads on the inside with a hex head used to tighten the fitting into the threaded opening. Merchant steel fittings are designed with Dryseal Taper Threads (NPTF) for more critical applications. NPTF Dryseal threads produce a mechanical seal by the mating and slight crushing of the threads when a wrench is applied to tighten the fittings.
