  • Description
25 mm male-theaded; 25 mm female-threaded nut end.  Includes 2 x PVC washers.  

125 mm long
Drill a 25 mm hole into your fibreglass or poly tank and fit with the application of a small bead of Sikaflex or Silicone to the washer faces.  Add a screw-on strainer on the inside of the tank to stop fingerlings going down the pipe.  We use this fitting-with-strainer as the overflow at the top of a fingerling/header tank, with the 19 mm version with a strainer and tap at the bottom.  
Below - example of a thru-tank fitting installed in a tank,
with a large strainer fitted to the inside.
