This double valve fitting is for aquarists who service canister filters and want to stop the water flow and disconnect hoses in seconds. Both valves close the line, so water does not drip, spill, or flow back into the tank during hose changes.
Why it matters
- Two shutoff valves allow the flow to be closed and the hoses to be separated quickly, without a separate clamp or pinch.
- ABS body is corrosion-resistant, so the fitting holds up under repeated contact with aquarium water.
- Rubber gaskets seal the connections, which limits leaks at the hose joints.
- Reusable and tool-free: it installs and removes by hand and can be taken apart for every service.

What it works with
