Air splitter/T-joint

Specifications

Description

An airline splitter distributes one aquarium air pump's output to more than one air stone, sponge filter or other air-driven device. A plain T connector makes a branch with one incoming line and two outgoing lines. A straight connector joins two lengths of hose without adding a branch. A gang valve combines several branches with a separate flow adjustment on each outlet. Choose a T connector for a simple split and a gang valve when several outlets need individual adjustment. Four-outlet and eight-outlet gang valves are documented examples. Match the connector to the airline size: the Pawfly fittings shown here specify 3/16 inch airline, with inside diameter explicitly identified for the T and straight connectors. The 40-piece connector pack contains 20 T fittings and 20 straight fittings; it is not a 40-outlet adjustable valve. Outlet count does not tell you how many devices your pump can supply effectively. Splitting shares the available airflow, and branches with less resistance can receive most of it. On an adjustable gang valve, close unused branches, open the branches in use, then gradually reduce the branch already bubbling until the others receive air. If the pump cannot supply all the connected devices, fitting a splitter with more outlets will not add capacity.
