This adapter screws into a quarter-inch MPT thread, and has a smooth fitting that slides inside 1/4-inch pipes.
It is often used on pump drainage points, and can also be screwed into air bleed valves. It can be used instead of a drain plug on Waterway Hi-Flo and Executive pumps, for example, as a way to bleed air out of the pump and help prime it quickly after the hot tub has been emptied and refilled.
We recommend adding a o-ring to ensure proper sealing.
