This adapter fits DIRECTLY onto the back of the XTOOL F1 / F2 ULTRA, and the inlet/outlet of the xTool Inline Fan 2 (IF2), xTool Air Purifier 2 (AP2) and allows you to connect to the original white F1 hose (~2.5")

It does not connect to the XTOOL F1 ULTRA hose.

This allows you to connect the xTool F1 to the AP2 using the white flexible hose (see listing images). This also allows you to easily connect the xTool F1 Ultra to the older and smaller xTool Desktop Air Purifier.

Build your custom smoke and fume extraction system with hose adapters allowing you to transition between various size hoses.

It is more likely that you would be looking to connect the smaller F1 to the newer and larger xTool AP2 as shown in this listing. However, it may be the case that you own the older and smaller xTool Desktop Air Purifier and have recently upgraded to the xTool F1 ULTRA but didn't buy the AP2 yet. Therefore you can connect these two pieces of equipment as well.

Alternatively, if you want to connect the F1 to the xTool IF2 inline fan using the white xTool hose you can do that as well. The larger end of this adapter fits directly onto the inlet of the IF2. This application is not pictured on this listing but is simple to understand.

I would highly recommend the xTool Inline Fan 2 (IF2) if you can route the exhaust outside. Check the link below for the best price from xTool. If you wish to run 4 inch hose on the outlet of the xTool Inline Fan 2, then you can use one of my AP2/IF2 to 4 inch hose adapters to achieve that.
