It's used to join two sections of 3-inch black iron pipe at a right angle in natural gas, propane, fire sprinkler, water supply, and compressed air lines. The fitting is suitable for general plumbing and industrial applications; some users also adapt black pipe for custom exhaust or air intake runs on heavy-duty trucks, though it is not a vehicle-specific part.
