PP Aquarium Airline Y Connector for 4 mm I.D. Tubing

Overview

• This aquarium airline Y connector joins three sections of flexible air tubing in a compact Y-shaped fitting. It can branch one airline into two, helping organize tubing layouts for aquarium aeration accessories such as air stones and air-driven sponge filters.
• The connector is made from polypropylene (PP) and has a translucent appearance. Each of its three arms features a tapered hose end and a raised retention ring designed to help hold the connected tubing in place and resist disconnection caused by air pressure. The overall length is approximately 40 mm, based on the supplied product diagram.
• All three connections are intended for tubing with a 4 mm internal diameter. This measurement identifies the tubing size, rather than the connector's measured outside diameter. The fitting provides an open three-way connection; airflow adjustment and non-return protection are separate functions provided by appropriate valves elsewhere in the air line.
