The Week Aqua Stainless Steel CO2 U-Bend Pipe with Check Valve does two jobs in one tidy piece. The curved 304 stainless steel pipe carries your CO2 line cleanly over the rim of the aquarium, so there is no soft tubing kinking or sagging across the glass, and the built-in quick-connect check valve helps prevent water from siphoning back down the line into your diffuser, solenoid or regulator when the CO2 shuts off.

It is made from 304 stainless steel for long-term corrosion resistance, with a polished finish that stays discreet on a rimless or rimmed tank. The check valve uses a push-to-connect quick fitting with a directional flow marking, so it installs in seconds and there is no doubt about which way it goes in the line.

Key features:

  • 304 stainless steel construction. Corrosion-resistant and built to last, with a clean polished finish
  • Tidy rim routing. The U-bend carries CO2 tubing neatly over the aquarium edge with no kinking or sagging
  • Built-in check valve. Helps prevent water backflow into your CO2 diffuser, solenoid or regulator
  • Quick-connect fitting. Push-to-connect with a directional flow marking for fast, foolproof installation
  • Fits standard 4/6 mm CO2 tubing via the barbed hose end
  • Compact and discreet. 70 mm tall with a 32 mm U-bend, suited to most tank setups

What's in the box:

  • 1 × Week Aqua Stainless Steel CO2 U-Bend Pipe with Check Valve

Installation:

  1. Hang the U-bend over the rim of your aquarium so the stainless curve sits across the glass edge and the check-valve end faces down toward your equipment.
  2. Push your CO2 tubing onto the barbed hose end, observing the directional flow marking on the check valve so gas flows toward the tank.
  3. Connect the other end of your CO2 line to your diffuser, solenoid or regulator as required.
  4. Run your CO2 and confirm bubbles are flowing in the correct direction before leaving the system unattended.
