This fitting connects tubing of different diameters at an angle to change the direction of flow between pipes or tubing.

This fitting meetings National Sanitation Foundation (NSF) standards 14, 51, and 61 for plastic piping systems, food equipment materials, and use with drinking (potable) water.Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Quick connect tube fittings allow flexible tubing to be quickly and safely connected and disconnected. When purchasing fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).John Guest manufactures push-to-connect fittings and pipe and plastic plumbing systems.
