How To Install a Spin Fitting

by | Feb 19, 2021 | How To

Today we are showing how to install a spin fitting into a tank.

When our customers order box tanks, they come in as simply a blank tank, as in, they don’t have any holes or lids with them. We will then spin weld plastic fittings into the tank for various and specific purposes. This makes them very customizable and special for each project.

Some of the functionality of these fittings will include inlets and drainage for tanks in

  • RVs
  • Boats or
  • Tiny homes

When customers require larger welded fittings or installed in a taller tank, we will often spin weld the fitting in with an extra bead of weld around the edges. We do this because often there is more head pressure due to the size of these tanks, and we want to ensure it is fully sealed, and ensure the fitting is secure.

To weld the fitting into a blank box tank first you drill out the hole a little bit larger so the fittings fit, then second, and this is particularly important, you need to get down to virgin plastic. Do this by scraping the surface in preparation for the welding.

Now you are ready to spin weld the fitting into the tank. You will use a router and simply spin weld the fitting in. You will want to keep pressure off the router until it’s at a high RPM and then allow the weight of the machine to sink it in for the final weld in.

At Clarion Tanks we have some larger spit fittings, everything from three eighths inch up to three inches in size.
