Orca Air Line Gate Green
Split or dial back air flow to exactly where it's needed. This Orca airline gate valve is a push-fit inline valve for standard 4 mm aquarium airline tubing. Turn it to open, close or hold anywhere in between, so one air pump can run several air stones, sponge filters or ornaments at different flow rates without extra plumbing.
Key features
- Push-fit fitting — pushes onto standard 4 mm airline tubing, no glue or clamps.
- Variable flow control — turn from fully open to fully closed, and hold anywhere in between.
- Lets one pump feed several outlets — pair with a T-piece to split air, then use a gate valve on each branch to balance the flow.
- Compact, inline fitting — sits directly in the airline with no extra bracket needed.

Suitable for, and not suitable for
Suitable for balancing air split by a T-piece across multiple air stones or sponge filters, or throttling a single air stone that's running too hard.
Not suitable for CO2 lines — this is an air valve, not rated for pressurised CO2 systems.
Care and maintenance
Rinse in fresh water if it becomes stiff or clogged with salt creep. Replace it if it no longer holds a flow setting.
Goes well with
- Orca Air Line T White — split one pump's output into two branches, then use this valve to balance the flow between them.
- Orca Small Air Stone — throttle flow to a single air stone with this valve.
- Bioscape Tropic Air Pump 500 Single w/Check Valve — the power source this valve regulates.

Common questions
What size airline does it fit?
Standard 4 mm aquarium airline tubing, the size used by most air pumps, air stones and sponge filters sold in Australia.
Can I use it on a CO2 line?
No. It's designed for low-pressure air pump lines, not pressurised CO2 systems.
Does closing it fully stop all the air?
Yes — as a gate valve it closes fully, unlike a simple flow restrictor.
Do I need one valve per outlet?
Only if you want to set each outlet's flow independently. A single outlet running straight from the pump doesn't need one unless you want to throttle it back.
