Active Aqua 8-Outlet Metal Air Manifold

Individually Controllable Air Splitter, 8 Outlets

Splitting one air pump line into several outlets with plastic barbed tees works until a tee cracks or a connection loosens under pressure, and none of those give you individual control over each line. The Active Aqua Metal Air Manifold splits one air pump line into multiple individually controllable outlets, built from copper and stainless steel with double-barbed ends for a tighter tubing seal than plastic splitters typically hold.

This 8-outlet manifold splits a single air pump line into 8 independently controllable outlets, built from copper and stainless steel.

Key Features & Benefits

• Copper and stainless steel construction — holds up to sustained pressure better than plastic splitters.
• Double-barbed outlet ends — grip tubing tighter for a more secure seal at each connection.
• Individually controllable outlets — let you adjust or shut off airflow to one line without affecting the others.
• Single-inlet, multi-outlet design — splits one pump line to feed several air stones or lines at once.

Who Should Use This Manifold

Growers running one air pump across multiple air stones or reservoirs, who want individual control over each line rather than a fixed plastic splitter, are the fit for this manifold.

About Active Aqua

Active Aqua's air-distribution hardware, sold through Hydrofarm, includes this manifold line alongside the brand's single- and dual-diaphragm air pumps.

Frequently Asked Questions

How many outlets does the 8-outlet manifold have?

It splits one air pump line into 8 individually controllable outlets. Each outlet can be adjusted or shut off independently of the others.

Why metal instead of plastic?

Copper and stainless steel hold up to sustained pressure and repeated tubing changes better than plastic splitters, which are more prone to cracking over time. The double-barbed ends also grip tubing tighter than a typical plastic barb.

Can I turn off individual outlets?

Yes, each outlet on the manifold can be controlled independently, so you can shut off or reduce flow to one line without affecting the others. That's useful when you're not running every outlet at once.

What size air pump do I need for this manifold?

Match your air pump's total output to the number of outlets you plan to run on this 8-outlet manifold, since splitting one pump's air across more active lines reduces flow per line. An undersized pump feeding all 8 outlets at once will underperform at each one.

How does it connect to my air pump?

The manifold's single inlet connects to your air pump's outlet tubing, then splits that supply across its double-barbed outlets. Standard air-line tubing pushes onto each barbed end for a secure connection.
