Black Left Right Schedule 40 Pipe Nipples

These right/left pipe nipples have standard right-hand threads on one side & reverse (left-hand) threads on the other. These are generally used for gas piping, when unions are not allowed. Gas fittings are specifically designed for use with gases, such as flammable propane or hazardous phosgene. These types of fittings have a reverse thread; meaning, the threads are cut in the reverse direction from all other fittings so that gas lines cannot be connected to air lines, water lines, or vent lines.
