It joins three sections of 3/8" OD nylon tubing, creating a branch in an air line without the need for clamps or wrenches. Featuring a brass body, it provides durable, leak-free connections at pressures up to 150 PSI and in temperatures from -40°F to 250°F. DOT-approved models are available for air brake applications, making this a common replacement part when adding or repairing air lines.
