Hose Barb Y Fitting – 3 Barbed Ends Wye – Ballast System

Wye fitting for joining two hoses and maintaining priority of flow direction.

This is used most often in plug and play ballast systems with aerator pumps and is much more efficient than traditional tee fittings. Ideal for combining vent and drain connections from one ballast bag together to exit through a single thru-hull fitting. Not suitable for use below the waterline.
