3/4" Y fitting. Black
A 3/4"Y fitting, typically black, is a modular plumbing component used in aquariums to split a single 3/4" hose into two 3/4" hoses. It allows for flexible and adjustable water flow direction within the aquarium system, often used in return lines and closed-loop systems. These fittings snap together and can be rotated to direct flow as needed.
