Product description

Send one return line in two directions. Loc-Line Y-Fittings split a single modular hose feed into two independently aimable outlets, so you can cover both ends of the tank, run a return alongside a spray bar, or feed two reactors from one pump. Pick the 1/2" Y, the 3/4" Y, or the 3/4" x 1/2" Y reducer to match the line you are running. Like every Loc-Line part, they snap together by hand and reposition in seconds. Made in the USA.

Why Aquarists Reach for Loc-Line

  • Tool-free assembly. Ball-and-socket segments click together and pull apart by hand. No glue, clamps, or cement.
  • Aim each branch on its own. Both outlets pivot and lock independently, so you can point one across the surface and the other toward a dead spot.
  • Repositionable for life. Re-plumb as your aquascape changes. The fittings hold their shape but never permanently bond.
  • Reef and freshwater safe. Inert acetal construction will not leach into your water.
  • Made in the USA by the original modular-hose manufacturer.

FAQ

Which Y do I need?
Match the Y to the line feeding it. Running 1/2" hose, choose the 1/2" Y. Running 3/4" hose, choose the 3/4" Y. Want to feed two smaller 1/2" outlets from a single 3/4" line, choose the 3/4" x 1/2" Y reducer.

Can I aim the two outlets in different directions?
Yes. Each branch is its own jointed run, so you can point them independently and re-aim them any time.

Do I need glue or threading?
No. Loc-Line snaps together by hand and stays put under normal return-pump flow. Pull it apart whenever you want to re-plumb.

Is it safe for reef and planted tanks?
Yes. Loc-Line is molded from inert acetal that will not alter water chemistry in fresh or salt water.
