4-Way Airline Gang Valve

The 4-Way Airline Gang Valve allows a single pump outlet to be split into four independently controlled lines, making it possible to run four air-driven devices from one pump with precise individual control. This is a staple accessory for hobbyists managing small breeding racks, quarantine setups, or community tanks with multiple air-driven components.

Each of the four outlets has its own valve — typically a thumbscrew or slider — that allows flow to be increased, reduced, or stopped entirely on that line without affecting the others. This flexibility is invaluable when managing tanks or devices with different aeration needs, or when one device is temporarily removed for cleaning.

The body is typically made from durable plastic with corrosion-resistant valve components, and all outlets accept standard 4mm airline tubing. Many models include a mounting clip for attachment to tank rims or cabinet walls. Pairing with a 4–8L/min pump provides adequate pressure for all four outlets to operate simultaneously.
