Aqua Source 3/8″ BSP Male Tee – 12mm Air

Aqua Source 3/8″ BSP Male Tee – 12mm Air

Threaded T-Connector for Dividing Airflow into Two 12mm Pond Air Lines

The Aqua Source 3/8″ BSP Male Tee – 12mm Air is a compact air-distribution fitting designed to connect to equipment with a compatible 3/8″ BSP female threaded port and provide connections for two suitable 12mm air lines. Its T-shaped configuration makes it a practical solution for dividing an air supply into two separate directions within koi pond, garden pond, filtration-room, and aquatic aeration installations.

Many pond aeration systems require air from a pump, manifold, valve, or threaded distribution point to be delivered to more than one destination. Instead of installing several separate adaptors, the male tee provides a single connection point from which two 12mm air-line branches can be created. These branches may then be routed towards compatible air stones, diffusers, aerated bottom drains, air rings, or other parts of the pond’s aeration system.

The 3/8″ BSP male threaded connection is positioned at the base of the fitting and is designed to connect to a correctly sized female threaded outlet. The two opposing 12mm connections allow air lines to extend in separate directions from the central threaded connection. This arrangement can be especially useful when equipment is positioned between two aeration zones or when a balanced, organised air-line layout is required.

Its compact configuration makes the fitting suitable for filter houses, pump rooms, equipment cabinets, manifolds, and pond-side installations where available space may be limited. The two air-line connections can help reduce the need for additional tees further along the hose route and may allow a cleaner distribution arrangement close to the main air source.

The fitting is useful when a single threaded air outlet needs to supply two separate air lines. For example, one branch may be routed towards an air stone while the second supplies a diffuser or another aeration point. The exact layout will depend on the pond system, air-pump capacity, connected equipment, and individual installation requirements.

It can be incorporated into a completely new pond aeration system or used when modifying an existing installation. The tee may be helpful when adding another aeration branch, repositioning equipment, replacing an unsuitable adaptor, extending an air system, or reorganising air lines inside a filtration area.

By placing the branching point directly at the threaded connection, the fitting can help create a more compact installation than using a separate male adaptor followed by an additional hose tee. This may reduce the number of individual components required and provide a more direct route between the threaded outlet and the two connected air lines.

The Aqua Source Male Tee can also be combined with other compatible 12mm air-line fittings, including straight connectors, elbows, valves, hose, and threaded adaptors. This allows pond owners and professional installers to construct an air-distribution system suited to the location of the pump, filtration equipment, and individual aeration outlets.

Whether it is being used to divide an air supply between two diffusers, connect two pond aeration zones, or create a compact branching point from a threaded outlet, the Aqua Source 3/8″ BSP Male Tee – 12mm Air provides a convenient solution for managing compatible 12mm pond air lines.

When to Use

• Dividing one threaded air outlet into two 12mm air lines
• Connecting two aeration branches to compatible equipment
• Supplying air to two pond diffusers or air stones
• Creating separate air routes for different areas of a pond
• Connecting air lines to a compatible pump or manifold outlet
• Adding a second branch to an existing aeration system
• Organising air lines inside a filter house or pump room
• Replacing a combination of separate adaptors and tee fittings
• Modifying or expanding a koi pond air system
• Creating a compact branching connection near equipment

How It Works

Carefully connect the 3/8″ BSP male threaded end to a compatible female threaded port on the pump, manifold, valve, adaptor, or other suitable air-system component.

Connect compatible 12mm air line to each of the two opposing tube connections. Ensure that both air lines are inserted and secured according to the fitting and hose requirements.

When the connected air system is operating, air enters through the threaded base of the tee and is distributed towards the two attached 12mm lines. Each line can then carry air to its connected diffuser, air stone, aerated drain, or other aeration component.

Before installation, confirm that the thread type and air-line size are compatible. Start the threaded connection carefully to avoid cross-threading and do not apply unnecessary force.

The amount of airflow received by each branch will depend on the complete system layout and connected equipment. Separate compatible air-control valves may be required when individual adjustment or isolation of each branch is needed.
